2 of 36 Display and DIP Switches Lock / Unlock (DIP Switch #1) Use the Lock / Unlock DIP switch to lock or unlock the Access Level of the 161. • • To unlock the Access Level, set the DIP switch to the unlocked (left) position. • • To lock the Access Level, set the DIP switch to the locked (right) position. Once locked, a padlock is displayed in the lower right corner of the display and the Access Level cannot be changed. Note: The tN4 System Control’s Lock / Unlock DIP switch overrides the Lock / Unlock DIP switch on the 161. Set the tN4 System Control’s Lock / Unlock DIP switch to the Unlock position before Access Levels can be changed on the setpoint control. tN4 System Control (DIP Switch #2) A tN4 System Control is a control, not a thermostat, that the Setpoint Control 161 connects to through the tN4 bus. All tN4 compatible Outdoor Reset Modules are tN4 System Controls.

© 2007 D 161 - 08/07 The Access Level restricts the number of Menus, Items and Adjustments that can be accessed by the user. The Access Level setting is found in the Miscellaneous (MISC) menu. Select the appropriate access level for the people who work with the setpoint control on a regular basis. The 161 has five Access Levels: • • Advanced (ADV): access to all settings • • Installer (InST): settings required for installation • • User (USEr): for property owners • • Limited (LTD): limited temperature adjustment • • Secure (SEC): for commercial and public installations In the Limited access level, the temperature can only be adjusted by +/-3°F (1.5°C) from the temperature setting entered prior to entering the Limited access level. In the Secure access level, all settings, including the temperature, cannot be changed. For more information, see the Miscellaneous (MISC) Menu section. In the following menu tables, the access level the item is visible in is shown in the access column. To adjust the Access Level: 1. Set the Unlock / Lock DIP switch to the unlock position. If a tN4 System Control is connected to the 161, the Unlock / Lock DIP switch on the tN4 System Control must be set to the unlock position. 2. Use the Menu button to select the MISC menu. 3. Use the Item button to select the Access item. 4. Use the Up and Down button to select the required Access Level.

After navigating menus, the display reverts back to the default item after 60 seconds of button inactivity. Application Overview The Setpoint Control 161 is designed to support four different applications. The items shown in the VIEW and ADJUST Menu change depending on the Application Mode. Set the application mode as follows: 1) Setpoint 2) Hot Tub 3) DHW Tank 4) Floor The VIEW and ADJUST menus list which of the four application items are visible based upon the mode column. The TIME, SCENE, SCHD (Schedule) and MISC (Miscellaneous) menus are the same for the four application modes.

6 of 36 Mode 4 Floor Relay 1 Pulse Width Modulation (PWM) Operation PWM operates by centering the throttling range around the target setpoint temperature. PWM is best suited for large heating loads that do not change rapidly in temperature such as radiant floors. Heating Operation When the temperature is at the setpoint, Relay 1 is on for 50% of a cycle and off for 50% of a cycle. When the temperature is 1/2 of the throttling range below the setpoint, Relay 1 is on for 100% of a cycle. When the temperature is 1/2 of the throttling range above the setpoint, Relay 1 is off for 100% of a cycle. For ranges within the throttling range, Relay 1’s on time increases linearly as temperature falls. The throttling range is fixed at 3°F (1.5°C). The cycle length is either the same as the tN4 system control, or when a tN4 system control is not present, the cycle length is fixed at 15 minutes. Mode 3 DHW Tank Relay 1 On / Off Differential Operation The On / Off Differential operates by centering a differential range around the target setpoint temperature. On / Off differentials are best suited to heating loads that quickly change temperature. Heating Operation When heating, the setpoint control turns on Relay 1 when the temperature falls to 1/2 of the differential below the setpoint and turns off Relay 1 once the temperature reaches 1/2 of the differential above the setpoint.

© 2007 D 161 - 08/07 Application Mode 1 is a generic setpoint control operation using an on/off differential for heating. The sensor is required to be located at the temperature control point. The setpoint control can have an occupied temperature setting. The setpoint load is not heated during the unoccupied or away periods. Application Mode 2 is designed specifically to heat hot tubs using an on/off differential. A sensor must be located in a temperature well on the recirculation pipe. The hot tub can have an occupied temperature setting. Sequence of Operation Application Mode 1 - On / Off Setpoint SECTION A Load Application Mode 2 - Hot Tub SECTION B Relay 1 Operation Relay 1 operates using an on/off differential to maintain the load at the Occupied temperature. During the Unoccupied period, Relay 1 is operated to maintain 10°F (5.5°C) less than the Occupied temperature setting. During the Away scene, Relay 1 is operated to maintain the Hot Tub at 50°F (10.0°C). Relay 1 Operation Relay 1 operates using an on/off differential to maintain the load at the Occupied temperature. Relay 1 does not operate during the Unoccupied or Away periods. Setting the Setpoint Off The setpoint temperature can be set to Off. When set to Off, Relay 1 will not turn on. If the heating area is outdoors, or the heating system has the potential to freeze, it is recommended that the setpoint always be set to a temperature and not set to Off. The setpoint can be set to Off if the heating system can be drained or the pump should remain off. The setpoint control power should never be shut off, otherwise an error message will appear on the rest of the tN4 system.
