INTRODUCTION L-3380 ENGLISH 3 IMPORTANT PROGRAMMING NOTES TO INSTALLER AND END USER 1. If your air conditioning unit is Cool only (if it does not have a reversing valve), then you MUST select Cool Only Mode. DO NOT select Automatic Mode for a Cool Only unit. If Automatic Mode is selected and the thermostat calls for heat, the compressor will run. Since there is no reversing valve, the air conditioning unit will supply cool air when heating is desired. Cool Only units do not heat. See “Modes of Operation” on page 8 for more information on how to set the proper operating mode. 2. If your air conditioning unit has a Shaded-Pole (SP) fan motor instead of a Split-Capacitor (SC) High-Velocity (HV) fan motor, you MUST program “SP” into General Setting 8, “Fan Motor Type”, before operating the equipment. The SP units are recognizable by an overhanging blower motor. (The SC motor of an HV unit is inside the blower, and the unit has “VTD” or “HV” in the model number.) Only reprogram this General Setting if you do NOT have an HV blower. NOTE: Do not staple any sensor cables when mounting. MEMORY When the Smart Touch losses power, the operating parameters are retained for up to 2 years. When power is restored, the control resumes operating as last programmed. The Smart Touch has a battery backup. If the battery backup is removed, only time and date settings will be lost. NORMAL HEATING OR COOLING CYCLE In Automatic Mode, heating and cooling are supplied as required. If cooling is required, the system will start a cooling cycle when the cabin temperature exceeds the set point by 2°F (1.1°C) and will continue to cool until the temperature equals the set point. (See “General Setting, Set Point Temperature Differential”, on page 12 for instructions on how to reduce this variation to 1°F [0.55°C].) The cabin temperature must drop below the set point by at least 4°F (2.2°C) in order for the system to switch from cooling to heating. Similarly, if heating is required, the system will start a heating cycle when the cabin temperature is below the set point by 2°F (1.1°C) and will continue to heat until the temperature equals the set point. The cabin temperature must exceed the set point by at least 4°F (2.2°C) in order for the system to switch from heating to cooling. If you select Cool Mode, only cooling is supplied. If you select Heat Mode, only heating is supplied. The cabin temperature in either mode is maintained within 2°F (1.1°C) of set point by default. (See “General Setting, Set Point Temperature Differential”, on page 12 for instructions on how to reduce this variation to 1°F [0.55°C].) When the heating or cooling set point is satisfied, the compressor cycles off and the fan returns to low speed. The fan speed remains constant if Manual Fan Speed is selected. For more information on this feature, see “Modes of Operation” on page 8. (For CW systems only) When cooling or heating is required, the water valve will not open unless the water temperature is adequate. You can view the water temperature by pressing the Temperature indicator icon until the Water temperature is displayed. The fan remains in low speed until the adequate water temperature is available. Heat will be supplied when no heating is available only if the Optional Electric heater has been installed and programmed. Adequate cooling or heating water temperature is defined by the Water Temperature Differential setting, under CW Control Parameters. Its factory default is set at 15°F (8.3°C) differential from the ambient air temperature. REVERSING VALVE OPERATION (FOR DX SYSTEMS ONLY) The position of the reversing valve determines if the system is in Cool Mode or Heat Mode. In addition, the reversing valve is programmed to toggle in these situations: • When the system is running and heating or cooling is required, the reversing valve toggles to the opposite mode to reduce the starting surge of the compressor. • When a cooling or heating cycle is called for and if the system has been off for less than 75 seconds. • When a cycle is interrupted from the display panel by pressing the Power icon or changing the set point. Unnecessary valve toggling is limited to reduce reversing valve noise. You can totally eliminate valve toggling by programming the minimum compressor staging delay to 75 seconds or greater (see “DX Operational Setting Compressor Start Delay” on page 13 for more information). Power-On Reset, which occurs when the system is powered up, always initiates a valve toggle. NOTICE The system’s air sensor is located in the control’s display panel; therefore the display MUST be located on an interior wall at eye level. It must NOT be located in direct sunlight or inside a cabinet. If these conditions cannot be met, you must purchase the Optional Remote Air Sensor and install it in the return- air stream.

Smart Touch Cabin Control Installation & Operations Manual 4 L-3380 ENGLISH INSTALLING THE DISPLAY PANEL CHOOSING THE LOCATION Figure 3: Smart Touch Display Front Panel Before mounting the control panel, consider the location. The display panel’s built-in air sensor provides excellent room-air temperature sensing when properly located and installed. For air sensor location see Figure 3. Mount the display panel on an inside wall, slightly higher than mid-height of the cabin, in a location with freely circulating air where it can best sense average temperature. Its distance from the air conditioner must be within the 15 ft (4.5 m) length of the display cable (custom lengths available). Do not mount the display in direct sunlight, near any heat-producing appliances or in a bulkhead where temperatures radiating from behind the panel may affect performance. Do not mount the display in the supply-air stream. Do not mount the display above or below a supply-air or return-air grille. Do not mount the display behind a door, in a corner, under a stairwell or any place where there is no freely circulating air. If you cannot mount the display in a suitable location for accurately sensing room temperature, install the optional remote air sensor. MOUNTING THE DISPLAY 1. Make the cut-out for the display panel. Cut-out size is 2.900" (7.36 cm) wide by 2.165" (5.50 cm) high. 2. Plug one end of the display cable (8-pin connector) into the upper-right socket on the circuit board in the electric box and the other end into the back of the display panel. Figure 4: Smart Touch Display Mounting Dimensions (Drawing not to scale – not a template)

INSTALLING THE DISPLAY PANEL L-3380 ENGLISH 5 3. Secure the display panel to the bulkhead using the four screws provided. Do not use a screw gun and do not overtighten screws when mounting, because either method may damage the display. 4. When the display is securely mounted, mount the bezel over the display frame until it snaps into place. Figure 5: Smart Touch Display Top View Mounting Dimensions MOUNTING THE OPTIONAL SENSORS REMOTE AIR SENSOR Install the optional remote air sensor if the display cannot be mounted in a proper location for accurately sensing room temperature. Installing the remote air sensor overrides the display’s built-in sensor. The standard cable length for the remote air sensor is 7 ft (2.1 m). 1. Mount the remote air sensor in the return-air stream behind the opening of the return-air grille. 2. Plug its cable (6-pin connector) into the “ALT AIR” socket #J4 in the upper-left corner of the circuit board. OUTSIDE AIR TEMPERATURE SENSOR Install the optional outside air temperature sensor to monitor the temperature outside the cabin. Outside air sensor cables are available in various lengths. 1. Mount the sensor outside but not in direct sunlight. 2. Plug its cable into the “OAT” socket #J3. SERVICE SENSOR (FOR DX SYSTEMS ONLY) Install the optional condenser coil temperature sensor into the “SERVICE/H2O” socket #J5. Use of this sensor must be enabled by going to DX Operational Setting and then Pump Sentry feature. WATER INLET SENSOR (FOR CW SYSTEMS ONLY) When using the AH-Elite with a chilled-water air handler, plug the water-inlet sensor cable into the “SERVICE/H2O” socket #J5. Attach the sensor to the chilled-water inlet on the air handler. Ensure that the sensor makes good contact with the copper pipe. DO NOT attach to rubber hose.

6 L-3380 ENGLISH BATTERY BACKUP BATTERY BACKUP OPERATION The battery backup will last over 2 years of “powered-off time”. This means that if the Smart Touch is plugged into a control that is powered up, the battery is not being drained. Only when the AC power to the control board is powered off is the battery being drained in the Smart Touch itself. When the battery dies, is removed, or replaced, the only information that is lost is the date and time. No other information is lost. Also the screen lock PIN will be reset to its default (“1234”) when the battery gets removed or dies. This is done in case the locking PIN is forgotten and the display gets locked. All other programming parameters, calibrations, program scheduler settings, etc., are retained in flash memory forever, and do not use the battery power at all. When the battery dies, there will be no visible indication on the display during normal power up. What will happen is that upon a subsequent (AC) power down and power up, the user will immediately be prompted to set the date/time setting. This is their indication that the battery needs replacement. Note that if the battery were dead and the date/time were set correctly during a given AC power up, as long as the display has AC power, it would retain the correct date/time indefinitely. The next time AC power is removed, the date/time would again be lost and be prompted for upon the next AC power up. When the fresh battery gets installed, the next AC power up will also immediately prompt for the date/time setting. BATTERY BACKUP SPECIFICATIONS The battery backup is included from factory with the Smart Touch display Battery voltage: 3 V Battery type: CR 2032 BATTERY BACKUP INSTALLATION/REPLACEMENT Figure 6: Top View of Smart Touch Display 1. Turn off unit. 2. Unmount display from wall or panel. 3. Disconnect RJ 45 plug from the back of the display. 4. Detach battery compartment cover from the back of the display. 5. To install a new battery: a. Insert battery in battery compartment, with positive battery sign facing south or opposite to where the RJ 45 jack is. b. Once inserted, make sure metal lock is holding the battery in. 6. To remove or replace an old battery, pull down metal lock and at the same time pull out the battery.

MODES OF OPERATION OFF MODE When the control is in Off Mode, all control outputs are turned off. All settings are saved in nonvolatile memory. ON MODE When the control is in On Mode, power is supplied to the appropriate outputs and the display indicates the current state of operation. The operating and program parameters resume based on those last stored when the unit was operating. AUTOMATIC MODE When Automatic Mode is selected, the system provides both heating and cooling as required. The Auto Mode icon is shown. Cabin temperature in a given mode is maintained within 2°F (1.1°C) of set point by default. (See “General Settings, Set Point Temperature Differential” on page 12 for instructions on how to reduce this variation to 1°F [0.55°C].) If the system was most recently cooling, the cabin temperature must drop below the set point by at least 4°F (2.2°C) in order for the system to switch from cooling to heating. Similarly, if the system was most recently heating, the cabin temperature must exceed the set point by at least 4°F (2.2°C) in order for the system to switch from heating to cooling. This behavior prevents small temperature overshoots from causing the system to switch between heating and cooling when it is not necessary. COOL MODE When Cool Mode is selected, the Cooling mode icon is shown and only the cooling system operates as required. If the ambient temperature drops below the set point, the system will not automatically switch to the Heat Mode. HEAT MODE When Heat Mode is selected, the Heating mode icon is shown and only the heating system operates as required. If the ambient temperature rises above the set point, the system will not automatically switch to the Cool Mode.

OPERATION L-3380 ENGLISH 9 MOISTURE MODE Use Moisture Mode to help control humidity while you are away from the boat or away from a particular cabin. While the control is in the On Mode, press the Mode icon until the Moisture Mode icon is shown. Once Moisture Mode is enabled, the fan circulates the air for 30 minutes. During this time, the air temperature is sampled and entered into memory. After 30 minutes, a cooling cycle starts and continues until the temperature is lowered 2°F (1.1°C) or until the cooling cycle runs a maximum of one hour. Four hours after the temperature is satisfied or the cooling cycle times out, this cycle repeats. Moisture Mode will also prevent your boat or a particular cabin from dropping below a minimum temperature as a means to prevent the contents from freezing. When the temperature drops low, eliminating moisture may become less of a concern and maintaining some minimum temperature may become more important. After the 30-minute fan circulation, if the temperature is at or above the factory default setting of 50°F (10°C), a cooling cycle is started and runs as described above. However, if the temperature is below 50°F (10°C), a heating cycle will be started instead. The heating cycle will continue until the temperature reaches 50°F (10°C) or until the heating cycle runs a maximum of one hour. Four hours after the temperature is satisfied or the cooling/heating cycle times out, the entire cycle repeats, each time determining whether cooling or heating is required. See “General Settings, Humidity Mode Minimum Temperature” on page 12 for more information on how to adjust the 50°F (10°C) factory default to a different temperature that may better suit your particular requirements. The adjustment range is 40°F (4.4°C) to 75°F (23.9°C). NOTE for DX systems only: On systems configured with reverse-cycle heat, the Moisture Mode heat cycle will not be allowed to run when the ambient temperature is below 40°F (4.4°C). This is necessary to protect the condenser coil from freezing. Systems configured with electric heat will be allowed to run the Moisture Mode heat cycle regardless of the room temperature. FAN MODES Automatic Fan Mode Smart Touch has three automatic fan speeds available: High, Medium and Low. Automatic Fan Mode allows the Smart Touch to determine the required fan speed based on temperature differential. This permits a balance between the most efficient temperature control and slower, quieter fan speeds. To select Automatic Fan Mode, press and release the Fan icon until the word “Auto” above the fan speed graph is shown. Manual Fan Mode There are three manual fan speeds available: High, Medium and Low. Manual Fan Mode allows you to select and maintain a desired fan speed. When a Manual Fan speed has been selected, the speed is indicated by the Fan Speed bar graph. The bar level will increase as the speed is increased by the user. Press and release the Fan icon until the desired speed is reached. Fan-Only Mode Use the Fan-Only Mode to operate the fan for air circulation when no cooling or heating is desired. From the Off Mode press and release the Fan icon to start Low fan speed. Press and release again to select Medium fan speed. Press and release a third time to select High fan speed. Press and release a fourth time to turn off the fan or place it in Auto mode. Turning on the control will revert the fan to the Automatic Mode or the last selected manual fan setting. MAIN MENU Use the Main Menu settings to adjust operating parameters for your particular needs. Main Menu is also used to fine-tune the system for the most efficient operation within an installation. (Variables such as ducting, sensor location, and system layout affect system operation.) The control has factory default settings stored in permanent memory that can be recalled. For this see Main Menu, Control Parameters, and then Recall Defaults. Reprogrammed new settings can be saved as Memorized settings and can be recalled and saved at any time. See “Main Menu, Control Parameters, Memorize Settings, and Recall Memorized” on page 15 for details. NOTICE For DX systems only: If your air conditioning unit is Cool only (if it does not have a reversing valve) then Cool Mode MUST be selected. DO NOT set to Automatic Mode for a Cool-Only unit. If Automatic Mode is selected and the thermostat calls for heat, the compressor will run. Since there is no reversing valve, the air conditioning unit will supply cool air when heating is desired. Cool-Only units do not heat.

OPERATION L-3380 ENGLISH 11 4. Inside Temp Calibration This setting calibrates the ambient sensor within a range of ±10°F. Adjust this parameter to display the correct room temperature reading. Note that setting increments are in °F even when the control is set to display °C. Figure 12: Smart Touch General Settings Page 2 of 7 5. Temperature Units (°F/°C/Auto) The default setting is °F. Select °C for Celsius. (Celsius readings are displayed in tenths, for example 22.2°). Auto corresponds to “automatic by line frequency”, where 60 Hz automatically sets the unit to Fahrenheit or °F, and 50 Hz automatically sets the unit to Celsius or °C. 6. Reversed Fan Speed in Heat Reverse Automatic Fan Speeds during Heating allows the user to automatically reverse the fan speed during Heat Mode. This is to improve heat output in cooler climates. The fan will speed up as the set point is approached. Lowering the fan speed when the cabin is cold increases head pressure and helps raise supply temperature. Increasing the fan speed as the set point is approached also reduces unnecessary high-pressure faults. The fan switches to low speed when the set point is satisfied and the compressor cycles off. The fan can be programmed to operate the same as in cooling by selecting the Off option, which represents normal fan operation during reverse-cycle heating. 7. Electric Heat Option (On=use electric heat, Off=use reverse-cycle heat) Reversing valve toggle (energizing of reversing valve output) will not occur prior to compressor start-ups if electric heat is on. The valve output and Electric heat relay (for legacy PPIO boards) will both be energized when DX electric heat is called for. For CW systems, On=use electric heat and/or hydronic heat, Off=use only hydronic heat. The compressor output will be energized when CW electric heat is called for. Units not equipped with reverse-cycle heat may have an electric heater added. Set to “On” for the electric heat option or “Off” to disable. When programmed for electric heat, both the electric-heater relay and the valve relay are energized. This change supports newer circuit board revisions without the electric-heater relay. Therefore, circuit boards that do not have electric-heater relays require a display with software revision A15 or newer to properly energize the valve relay. Also, since the valve-relay output only supports a maximum of 15 amps at 115V AC or 10 amps at 230V AC (circuit boards revision F and newer) of resistive load, when installing an optional electric heater that exceeds this load, it is necessary to install an additional contactor that is rated to handle the full load of the electric heater. Please consult with Dometic Customer Service or with an authorized service technician for assistance. 8. Fan Motor Type The Split Capacitor default setting is correct for air conditioning units with high-velocity blowers. Only change the setting to Shaded Pole if your unit has a Shaded Pole fan motor, recognizable by a blower-motor overhang. (The Split Capacitor motor of a high-velocity unit is inside the blower, and the unit has “VTD” or “HV” in the model number.) 9. Filter Hours Setting Reminder for air filter cleaning or replacement is determined by the number of hours of fan operation. Filter Hours Setting can be set as a reminder to clean or replace the unit’s air filter. Select the number of operating hours until the filter reminder appears. Parameter choices are between 100 hours and 2500 hours. Dometic recommends that you check the air filter at least every 500 hours of operation. The default setting is off. Once set, the timer keeps track of the total amount of run hours that the fan accumulates. Once the timer setting is reached, flashes briefly on the status icon until it is cleared. Display of the room temperature continues and the normal operation of the system is not affected. The reminder can only be cleared and the timer reset via General Setting, and then Filter Hours Setting. Figure 13: Smart Touch General Settings Page 3 of 7 10. Filter Hours Reset The Filter Hour Reset setting shows the number of filter reminder hours accumulated and allows clearing via a CLR icon. This parameter displays the current elapsed time in hours since the timer was started or reset. To clear the reminder, press the CLR icon. This resets the value to 0 and restarts the timer.

12 L-3380 ENGLISH 11. CAN Bus Unit ID This parameter selection icon is grayed out whenever the Smart Touch is not plugged into a Passport I/O board with the CAN bus daughterboard option. In other words, this parameter displays only when CAN- bus network capability is available and the Smart Touch is plugged into a networked Passport I/O power and logic board. This parameter does not display when the Smart Touch is plugged into a standard board. Each control on the same CAN-bus network must be assigned a unique Unit ID (0 -255). For example, the control that is set to 5 will respond to commands with a destination address of 5. Figure 14: Smart Touch General Settings Page 4 of 7 12. CAN Bus Group ID This parameter selection icon is grayed out whenever the Smart Touch is not plugged into a Passport I/O board with the CAN bus daughterboard option. In other words, this parameter displays only when CAN-bus network capability is available and the Smart Touch is plugged into a networked Passport I/O power and logic board. This parameter does not display when the Smart Touch is plugged into a standard board. Assign the address for the control’s CAN-bus network group (0 - 255). This number should be unique and different than any CAN-bus Unit ID. For example, all controls that are set to 100 will respond to commands with a destination address of 100 (in addition to responding to commands that target their individual Unit IDs). 13. Voltmeter Calibration This parameter allows adjustment of the line voltage reading as measured by the Smart Touch. This setting displays the voltage being read by the power and logic circuit board. It displays a live reading of the voltage and can be manipulated by pressing the Up or Down icons. Calibrating this parameter provides a more accurate voltage level when calculating low voltage. Use a reliable voltmeter as a reference when adjusting this parameter. Figure 15: Smart Touch General Settings Page 5 of 7 14. Set Point Temperature Differential This parameter is the temperature differential in Fahrenheit for all modes of operation: Automatic, Cool, or Heat. Refer to “Modes of Operation” on page 8 for more information on how this parameter affects these modes. By default, this parameter setting is 2°F (1.1°C). It can be set to either 1°F (0.55°C) or 2°F (1.1°C). Setting this parameter to 1°F (0.55°C) will result in the control maintaining the room temperature closer to the desired set point. However, this may result in more frequent shorter-duration cooling or heating cycles. In most cases, the factory default of 2°F (1.1°C) is adequate for maintaining a comfortable temperature variation around the desired set point. If you desire less variation in temperature, set this parameter to 1°F (0.55°C). 15. Humidity Mode Min Temp This parameter is the minimum room temperature in Fahrenheit for which Moisture Mode will run a cooling cycle to remove moisture from the air. If the room temperature is below this parameter setting, Moisture Mode will run a heating cycle instead. By default, this parameter is set to 50°F (10°C), and it can be adjusted between 40°F (4.4°C) to 75°F (23.9°C). Please refer to the description of “Moisture Mode” on page 9 for more information on how Moisture Mode functions and utilizes this parameter. Figure 16: Smart Touch Outside Temperature Indicator 16. Auto Fan Speed Temp Differential This setting sets the incremental differential (with cumulative steps) between the ambient temperature and the set point temperature at which the fan speed will increment to the next speed. Note that there is 1°F hysteresis in the auto fan speed differential to prevent the speed from changing if the room temperature changes by a fractional degree causing speed fluctuations. Also General Settings Reversed Fan Speeds in Heat, and Set Point Temperature Differential, both have an effect on the operation of the auto fan speed.

OPERATION L-3380 ENGLISH 13 Figure 17: Smart Touch General Settings Page 6 of 7 17. Supply Air Temp Limit Enabling this parameter has no effect unless General Setting Electric Heat Option is also enabled (set to “On”). Use of this parameter requires that the OAT sensor is placed in the supply air stream immediately downstream of the blower discharge. This setting is the maximum the supply air discharge temperature will allow. Heat mode will be shut down if the temperature of this sensor exceeds the programmed setpoint. Heat mode will be restored once a 10°F hysteresis has been satisfied. Heat mode will also be restored if power is cycled to the control and the OAT sensor temperature is less than the setting but still within the hysteresis. There is no fault indication when this condition occurs and no lock-out. The discharge temperature can be displayed by pressing the temperature icon until the temperature title shows Outside (same as viewing the Outside Air Temperature). 18. DX/CW Mode Selection Choosing “Set by Jumper” preserves the status of the Passport I/O operation where if the “Cut for Chill” jumper on the main PPIO board is not cut, the Smart Touch will operate in DX mode, and if the jumper is cut, the Smart Touch will operate in CW mode. The other choices for this parameter allow the jumper to be overridden, if desired. Figure 18: Smart Touch General Settings Page 7 of 7 19. Inside Temp Sensor Selection If the alternate air temperature sensor is plugged into the Passport I/O main board, it is used as the inside temperature, and if it is not plugged in, the built-in display temperature sensor is used for inside temperature. This parameter allows this behavior to be overridden if desired. 20. Fan Operational Mode The fan can be set to run continuously whenever the system is turned on, or it can be set to cycle on and off in conjunction with the cooling or heating cycles. 21. Dual Temp Set Points When Off, there is only one common set point, which is adjustable and used for both heating and cooling. When On, two separate set points are settable and used, one for cooling and one for heating. DX Operational Settings 1. Compressor Start Delay The compressor staging delay is for installations where more than one system operates from the same power source. Setting different staging delays allows compressors to start at different times when power is interrupted. Stage the units at least 5 seconds apart. Minimum delay is 5 seconds and maximum is 135 seconds. 2. Failsafe To protect the equipment, certain fault conditions trigger a lockout: The control shuts down and will not restart until the fault is repaired. The lockout condition depends on a combination of the failsafe level you have programmed as well as the type of fault detected. There are 4 different Failsafe levels to choose from. a. Faults Not Detected - This level provides minimal failsafe protection and is not recommended. Only the “Air Sensor Failure” fault is detected and displayed. The control shuts down and will not restart until the fault is repaired. When the fault is repaired the control restarts after a 2-minute delay. b. Faults Detected But Not Displayed - This level provides the failsafe actions of Faults Not Detected, plus all other faults are detected but not displayed. The system shuts down for 2 minutes or until the fault is cleared, whichever is longer. The system restarts when the fault is cleared. c. Faults Detected and Displayed - This level provides the failsafe actions of the previous two levels, plus all faults are displayed. The system shuts down for 2 minutes or until the fault is cleared, whichever is longer. The system restarts when the fault is cleared. d. Faults Detected and Displayed with Lockout - This level provides the failsafe actions of previous 3 levels, plus the system will lockout after four consecutive High Pressure Fault, Low Pressure Fault, or High Water Temperature in Condenser Coil faults, and you can clear the lockout. The system shuts down for 2 minutes or until the fault is cleared, whichever is longer. To clear the lockout, press the Power icon once to Off Mode and press it again to On Mode.

14 L-3380 ENGLISH Figure 19: Smart Touch DX Settings Page 1 of 2 3. Low Voltage Monitor The Smart Touch has a built-in voltmeter circuit that monitors the AC input voltage. Depending on whether the input power supply is 115V AC or 230V AC, this parameter can be set to “Off”, 75-120V AC of 115V AC input power, or 175-240V AC of 230V AC input power. The factory default setting is Off. When this parameter is set to 75-120 or 175-240V AC, the Smart Touch checks the AC input voltage prior to each cooling or heating cycle and prevents the compressor from starting if the voltage is less than the one set. This provides extra protection for the compressor and components within the system during low voltage (brownout) conditions. If this low voltage condition occurs, the fault code Low AC Voltage appears in the Status icon in the Main display. The fault will continue until the AC input voltage rises above selected voltage value, at which time the Low AC Voltage fault code clears automatically and the cooling or heating cycle will commence. After the compressor is started, the low voltage monitor continues to check the AC input voltage. If it drops below the specified setting and remains below for 5 minutes, the system will shut down and the Low AC Voltage fault will be displayed. The system will remain shut down until the voltage goes back above the specified setting. Once the voltage is restored, after the normal fault recovery delay, the system will be restarted. As with all faults, system lockout (sustained shutdown) will occur after the fourth consecutive Low AC Voltage fault. See Fault Handling, History & Run Hours for further details on system lockout. 4. De-Ice Cycle The de-icing cycle prevents ice buildup on the evaporator coil during extended periods of cooling operation. Installation variables such as grille sizes, length of ducting, insulation, and ambient temperatures determine the run time required to achieve set point. Factors that substantially increase run time include operating the system with hatches and doors open and programming an unrealistic set point (e.g. 65°F/18.3°C). Such situations can cause the evaporator to form ice on warm humid days. De-icing is accomplished by closely monitoring the room air temperature in 10-minute intervals during a cooling cycle. Depending on the parameter value and the change in room temperature during these monitoring intervals, the control performs various actions to prevent ice from forming or to melt ice that has already formed. This is accomplished by short compressor shutdown periods combined with a one- speed increase in fan speed and by periodic Heat Mode cycles with the fan turned off. The parameter setting for the de-icing feature depends on whether you are using the optional alternate air-temperature sensor or the display’s built- in room air-temperature sensor. Installation of an optional alternate air temperature sensor (located in the return air path) greatly increases the effectiveness of the de-icing feature, and this option should be considered whenever the display sensor cannot read the room temperature accurately. • If using an optional alternate air temperature sensor, set this parameter to Enable with 5°F/3°C Sensor Differential to turn the de-icing feature on, or to Off to disable. • If using the display’s built-in room air temperature sensor, this feature has 2 selectable behavior modes. Both modes attempt to compensate for any temperature discrepancy the display sensor experiences. (Although discrepancy is not typical, installation variables such as where the display is placed inside the room – near an open door or in direct sunlight – can affect how accurately it reads the actual room temperature.) Set this parameter to or Enable with 5°F/3°C Sensor Differential to assume the display sensor may be reading the room temperature as much as 5°F (2.8°C) greater than the actual evaporator temperature (standard). For more extreme installations, set this parameter to Enable with 7°F/4°C Sensor Differential to assume the display sensor may be reading the room temperature as much as 7°F (3.9°C) greater than the actual evaporator temperature. The setting of the second option should only be used if the selection of the first option does not prevent evaporator ice from forming. 5. Pump Sentry Smart Touch can be equipped with an optional temperature sensor that is used to monitor the condenser coil temperature. The sensor is plugged into the “SERVICE/H20” sensor jack. The Pump Sentry setting can be programmed for a temperature between 100 and 150°F (37.8 and 65.6°C), depending on seawater temperature and the system type. (Note that setting increments are in °F even when the control is set to display °C.) Connect the water sensor to the condenser coil outlet and insulate it. When the coil temperature rises above the programmed value, the pump and compressor are shut down and “Pump Sentry Fault” flashes in the display. 6. Pump Operate Mode Cycle pump with Compressor to increase pump life and conserve electricity. The pump can be programmed to cycle on and off with the compressor. The pump can also be programmed to operate continuously whenever power is applied. To program the pump for continuous operation, set the setting to Continuous.

OPERATION L-3380 ENGLISH 15 Figure 20: Smart Touch DX Settings Page 2 of 2 7. Low Pressure Detection When selecting “Set by Jumper”, if the “Enable LP” jumper on the main PPIO board is not cut, the low pressure switch will be disabled, and if the jumper is cut the low pressure switch will be enabled. Choosing “Disabled (Use Caution)” will force the Smart Touch to ignore the low pressure switch, treating it as disabled even if the jumper is cut. This should only be done when advised by Dometic Customer Service. As with all faults, system lockout (sustained shutdown) will occur after the fourth consecutive Low Pressure fault. CW Operational Settings Figure 21: Smart Touch CW Settings Ambient Air to Water Temperature Differential 1. Water Valve Force Open This parameter opens the water valve to bleed air from the system. “On” forces the valve open for 4 hours while the Smart Touch control is turned off. If Cool mode is activated or if AC power is interrupted to the control’s electric box during this 4-hour period, this valve override feature is canceled. You can return the valve to normal operation at any time by changing the setting back to “Off”. 2. Water Temp Differential This parameter sets the temperature differential between ambient air temperature and hydronic water temperature that controls the water valve. For example, selecting 10°F opens the valve when water temperature is 10 degrees less than ambient in cooling mode and 10°F greater than ambient in the heating mode. Careful selection of the temperature differential can fully utilize the ship’s heating and cooling resources. For example, while in cooling mode and using a 10 degree value, the valve will open to allow some cooling while the hydronic system is coming down to temperature. See the following figure for a graphical explanation of this parameter.

32 L-3380 ENGLISH MAINTENANCE SYSTEM COMPONENTS REVERSING VALVE (FOR DX SYSTEMS ONLY) Reverse-cycle (cooling and heating) units have a reversing valve that must be energized periodically to keep the internal parts moving freely. To do this, switch the air conditioner unit into Heat Mode for a few seconds once a month. SEAWATER STRAINER (FOR DX SYSTEMS ONLY) Ensure your pump receives adequate seawater flow by regularly cleaning the strainer basket. Periodically check the overboard discharge for a steady stream of water. Check seawater intake speed scoop for obstructions. Make sure hoses are not looped, kinked or crushed. CONDENSER COIL (FOR DX SYSTEMS ONLY) A marine-growth-fouled coil reduces efficiency, raising total system pressure and decreasing its ability to produce cold air. 1. With the system turned off at the circuit breaker on the ship’s panel, disconnect the inlet and outlet connections of the condenser coil. 2. Use chemical-resistant hoses (white PVC 5/8" I.D., etc.) to connect the inlet of the condenser coil to the outlet of a chemical resistant, submersible pump (P-500 pump, etc.) and let the hose connected to the coil outlet flow freely into the container mentioned below. 3. Place a strainer or piece of screen over the inlet of the pump and submerse the pump into a container filled with a 5% solution of muriatic or hydrochloric acid and fresh water or use a premixed over-the-counter solution. Use as large a container as possible to hold the solution (5-25 gal [19-95 liters]). 4. Power the pump and circulate the solution through the condenser coil for 15-45 minutes depending upon the size of the coils and the extent of the contamination. Visual inspection of the solution in the container should indicate when the contamination removal has stopped. 5. Circulate fresh water through the coil to flush any residual acid from the system. 6. Restart the system and check operational parameters to ensure thorough cleaning has taken place. Additional cleaning may be necessary with extreme contamination. RETURN-AIR FILTER Check the return-air filter about once a month and clean as necessary. To clean the filter, remove it from the unit, rinse with water, air dry and reinstall. WINTERIZATION (FOR DX SYSTEMS ONLY) There are several methods of winterization, some of which work better than others. Any method that causes the antifreeze solution to flow downward is the method of choice. By this means, the antifreeze solution displaces any trapped water and eliminates the possibility of it freezing in hidden areas. Choose the method that works best for you. In the following methods, the first two use a 50/50 nonpolluting biodegradable antifreeze/water solution: • Pump antifreeze solution into the overboard thru-hull fitting, and discharge through the intake thru-hull fitting. • Use the seawater pump to pump antifreeze solution through the system and discharge through the overboard thru-hull fitting: Close seacock, remove hose from strainer discharge, raise hose above pump (so pump does not lose its prime) and pour in antifreeze solution. Pump solution through system. The strainer and hose to seacock need to be drained of water. • Use pressurized air injected at the overboard discharge fitting to force system water through the seawater intake fitting, thus expelling any trapped water from the system. NOTE: For the purpose of protecting the environment, dispose of any contaminated acid solutions in accordance with federal, state and/or local regulations. CAUTION Avoid spilling or splashing the solution. Follow all warnings and recommendations given by the manufacturer of any acids or premixed solutions.

Installation and application of Dometic components is not warranted by Dometic, because Dometic has no control or authority over the selection, location, application, or installation of these components. SECTION III - COVERAGE PERIOD What is the period of coverage? (See Table of Warranty Periods) All Dometic components bear a data plate on which there are model and serial numbers. The serial number is date coded. To determine whether or not any Dometic component is in warranty, proceed as follows: 1. Determine the manufacture date of the component from the serial number on the data plate. If you are not familiar with the date code, write or call the Dometic Customer Service Department to obtain the manufacture date. The hours of the Customer Service Department are 8:00 a.m. - 5:00 p.m. (USA, Eastern Standard Time Zone) Monday through Friday excluding holidays. 2. It is possible that there might exist a considerable time lag between the date a component is manufactured and the date it is put in service. In such instances, the date of manufacture could indicate that the item is out of warranty. However, based on the date the equipment is first put in service, the item may still be covered by the Dometic warranty as described in Section I. For proof of date put in service, Dometic will require a copy of the bill of sale of the Dometic equipment from the installer or new boat dealer to the original owner. SECTION IV - GETTING SERVICE How do you get service? Please read the following Warranty Procedure: If the failure of a Dometic component is determined to be covered under the Dometic warranty and the time in service is determined to be within the warranty time limit, the owner has the following three options: 1. Preferred option: Have a Dometic authorized Servicing Dealer, perform the work needed. The customer needs to call Dometic Customer Service Department for a recommendation as to the closest dealer. If the customer already knows an authorized servicing dealer, the dealer should be contacted directly. 2. Second option: If the customer contacts Dometic Service Department for a Servicing Dealer and Dometic has no one in that particular area, Dometic will authorize the use of a local service company and Dometic will work with the local company to assist in any way possible. 3. Third option: The customer may send his equipment back to the factory to have the repair work done. Dometic will make every effort to return the equipment to the customer within a three week time period. If the claim represents a legitimate warranty problem, Dometic will pay the freight both ways. Dometic prefers option one first, option two second, and option three only if one and two are not available. The customer may contact the Dometic Service Departments at (804) 746-1313 (Virginia plant) or (954) 973-2477 (Florida plant) Monday through Friday, 8:00am - 5:00pm. After hours (evenings and weekends) technical support is offered through Dometic’s 24/7 Hotline at (888) 440-4494.
