The controllers are available with or without a front panel display and buttons. For units without a display and buttons, a separate, cable-connected terminal (E3-DSP) with display and buttons is available. All normal handling can be carried out using the display and buttons or by using E tool©, a software tool that runs on a computer connected to the controller with an E-CABLE model communication cable or a crossover network cable. Ventilation application, overview of functions The controller comes loaded with programs for control of a ventilation unit. The temperature controller is based on a supply air PI-controller for heating control with a pre-programmed set of control modes. A number of different control functions as well as analogue and digital input and output functions can be bound to this controller. Certain functions are necessary, while others can be considered optional. This flexibility means that what is shown in the display may differ from one unit to another, depending on which functions have been selected. Functional choices are not made in the operator level, but in the Admin access level by educated personnel with specialised knowledge. The same applies to other configuration. The program for an air handling unit contains, apart from other things, the following functions: Different temperature control modes: • Supply air temperature control, with or without outdoor temperature compensation. • Room temperature control (cascade control). • Extract air control (cascade control). • Seasonal switching between supply air temperature control and room/extract air temperature control. • Outdoor compensated room/extract air control.

guide, revision F 4 • Extra, separate temperature control circuit for after-heaters, etc. • Extra control sequences Y4 and Y5 (in addition to Y1, Y2 and Y3) for free integration into the controller output. With control of: • Heat exchanger (liquid connected, plate or rotating) or mixing dampers. • Heating coil: Water with or without frost protection or electric with high temperature limit switch. • Cooling: Water or DX cooling in up to 3 steps. • Circulation pumps for heating, exchanger and cooling. • Recirculation dampers. Fan control • 1- or 2-speed supply air and extract air fans. • Frequency controlled supply and extract air fans with pressure or flow control, manual control or external control from a VAV system. • Pressure controlled supply air fan with slave connected extract air fan (output dependent or flow dependent) or opposite function (pressure controlled extract air fan with slave connected supply air fan, output dependent or flow dependent). Humidity control Either humidification or dehumidification, or both humidification and dehumidification, can be used. Timer control For starting and stopping the unit. Up to 5 timer outputs for control of external functions such as lighting, door locks etc. Demand controlled ventilation In buildings with strongly varying occupancy the fan speeds or mixing dampers can be controlled by the air quality measured by a CO2 sensor. Support control When using the control function room control or extract air temperature control, it is possible to utilise support-heating and/or support-cooling. Free cooling When this function has been activated it is used during the summer to cool the building during the night by using cool outdoor air, thereby reducing cooling needs during the day. Free heating If the outdoor temperature is higher than the indoor temperature and there is a heating demand, the recovery damper will not open for recovery but instead open fully for outdoor air. This may occur during low night-time outdoor temperatures, when the room has been cooled considerably and the outside heat is rising faster than indoors. This function is activated at the same time as “Free cooling”.

When this function is active, the mixing damper signal will be overridden to recirculation if the outdoor enthalpy is higher than indoors. Pretreatment Damper and pump control for preheating or precooling of the outdoor air via an underground intake channel. Cooling recovery If the extract air is colder than the outdoor air and cooling is required, the heat exchanger control is reversed in order to return the cool extract air. Recirculation control Recirculation of air using a supply air fan and (optionally) extract air fan and a recirculation damper with or without temperature control. Used as a recovery function or during heating with support control during the night. Recirculation control is available as an analogue or a digital function. Step controllers Heating/Cooling As an alternative to the analogue control of ”Actuator heating Y1” or ”Actuator cooling Y3” step controllers can be used for controlling heating or cooling in steps using digital control. Change-over In 2-pipe systems where a combination heater/cooler is operating together with a heat pump, Change-over is a function that enables using the same pipe for both heating and cooling, depending on which is currently required. It uses the output Y1 Heating/Y3 Cooling.

guide, revision F 6 Display, buttons and LEDs This section is applicable to Corrigo units with display and buttons but also to the hand terminal E3-DSP. For third generation controllers, it is also possible to connect an external display to units that are equipped with a display and buttons. Display The display has 4 rows of 20 characters.

guide, revision F 8 The menu system Navigating the menus The choice of access level/user access determines which menus are shown. The display to the left is normally shown at start-up and is located at the basic level of the menu tree. The appearance of the start display may vary since there are 5 types to choose from during configuration. The text in the first row can also be changed using E tool©. Sp and Av are setpoint and actual value for the supply air controller. This also applies when using cascaded room temperature or extract air temperature control. Actual value = The current measured temperature. Setpoint value = The desired configured temperature. Pressing ARROW DOWN will move you through the menu choices at this, the lowest level. ARROW UP will move you back through the choices. Which menus are shown depends on which access level you are using (see the section Access rights for more information about logging on to higher levels). The basic access level, the level normally active when you have not logged on, only shows a limited number of menus and submenus: Running mode Here, you can view and set the unit’s running mode, as well as view selected control functions and alarm events. Temperature, Air control and Humidity control Here, relevant values and setpoint values are displayed. Setpoints can only be changed if you have Operator access or higher. Time settings Here, the time, date and set running times are shown. Values can only be changed if you have Operator access or higher. Access rights Here, you can log on to a higher level, log off to the basic level and change the password. A user with Normal access, the basic level, can view a limited selection of menus. The unit’s running mode can be changed and alarms acknowledged. If you have Operator access, you can access more information and change other operation parameters like setpoints and time functions. To get to the next menu level, use ARROW UP and ARROW DOWN to place the display marker opposite the menu you wish to access and press ARROW RIGHT. If you have sufficient log on privileges the display will change to the menu you have chosen. At each level there may be several new menus through which you may move using the ARROW UP and ARROW DOWN buttons.

To go to a previous menu level, press ARROW LEFT. Change parameters In some menus there are parameters that can be set. This is indicated by the yellow LED with  flashing. A quick blinking (2 times/s) indicates that the parameter can be changed using the present user access. A slower blinking (1 time/s) indicates that a higher user access is required to change the parameter. To change a parameter, first press the OK button. If you need a higher user access than you have to change the parameter, a log on menu will be displayed, see below. Otherwise, a cursor will appear at the first settable value. If you wish to change the value, do so by pressing the ARROW UP and ARROW DOWN buttons. In numbers containing several digits you can move between the digits using the ARROW LEFT/RIGHT buttons. When the desired value is displayed press OK. If there are further settable values displayed the cursor will automatically move to the next one. To pass a value without changing it, press RIGHT. To abort a change and return to the initial setting, press and hold the C-button until the cursor disappears. Collected here are a number of menus showing running mode, selected functions, alarm events and status of inputs and outputs. Running mode Running mode unit The unit’s running mode can be changed without logging on. The running mode can be set to Auto, Off, Manual reduced run or Manual normal run. The Auto mode should normally be used. Off can be used to stop the unit for service and similar. Manual normal run or Manual reduced run will start the unit even if the timer says that the running mode should be “Off”. If the running mode is set to Off, Manual normal run or Manual reduced run, a C alarm is activated: Running mode Manual. The alarm automatically resets when the running mode is set to Auto again. Running mode Selected functions Alarm events Input/Output Running mode Auto

guide, revision F 10 Shows the accumulated running times for the fans. Selected functions In these menus, you can see how some of the most important functions have been configured. Changes cannot be made. Heater, exchanger and cooling type. If one of the functions is not used, it will be shown as ”Not used”. This function is used during the summer to cool the building night-time using cool outdoor air, thereby reducing the need for cooling during the day and saving energy. Support control is used for adjusting the room temperature outside of the normal running time. If there is a heating or cooling demand in the room, the unit will start and the temperature will be adjusted. The fire function determines the settings for the fire dampers and the unit’s running mode when a fire alarm is activated. Frost protection is normally always used in water heating systems. The cooling recovery function starts the heat exchanger in order to return cooling from the extract air when the extract air is colder than the outdoor air and cooling is required. An analogue input can be configured for an external setpoint device e.g. TG-R4/PT1000.

guide, revision F 12 Temperature Here you can view all actual and setpoint values for temperature control. The menu is visible to all users, regardless of log on level. However, to make changes you need at least Operator authority. Only menus for activated functions will be shown. Setpoint Supply air temperature control Here, actual and setpoint values are shown, as well as the outdoor temperature if a outdoor sensor has been configured. This is a read-only menu. No settings can be made here. Submenu: Setpoint. Setpoint Outdoor temperature compensated Supply air control Here, actual and setpoint values are shown, as well as the outdoor temperature if a outdoor sensor has been configured. This is a read-only menu. No settings can be made here. Submenus: Setpoint In control modes Supply air control/Room control and Supply air control/Extract air control , the setpoint relationship is used when supply air control is active. Use the eight breakpoints to generate a setpoint / outdoor temperature relationship. In-between-values are calculated using straight lines between breakpoints. Setpoints for temperatures lower than the lowest breakpoint and higher than the highest breakpoint are calculated by extending the line between the two last breakpoints at either end.

guide, revision F 14 This function operates according to the assumption that one may accept a slightly higher indoor temperature when it is warm outside and vice versa, providing an excellent opportunity for conserving energy. Support control heating/Support control cooling Support control is normally used when room temperature control or extract air control has been configured, to prevent a too large offset in temperature when the unit is “Off”. “Support control Heating” or “Support control Cooling” will run if support control is configured, the running mode is "Off" (timer control OFF and not in extended running) and if conditions call for support control. Minimum run time is settable 0 to 720 minutes (FS= 20 minutes). Frost protection temperature Relevant value for the water temperature at the frost protection sensor. Frost protection can be set to function either on Y1, Y4 or on both. The function only supports a single sensor.

If the temperature at the de-icing sensor drops below the setpoint value, the de-icing function is started. It is stopped when the temperature has risen above the setpoint plus the set differential. Heat exchanger efficiency monitoring The function calculates the heat exchanger temperature efficiency in % when the output signal to the exchanger is higher than 5 % and the outdoor temperature is lower than 10°C. The function requires an extract air sensor, an exhaust air sensor and an outdoor sensor or an efficiency sensor, extract air sensor and outdoor sensor. When the control signal is lower than 5% or the outdoor temperature is higher than 10°C the display will show 0%. Recirculation The first of the three below menus can be found under Configuration in the controller. The fourth menu is located under Temperature. Recirculation is a function for mixing the air in the room using the supply air fan. The function can be used even when there is no heating or cooling demand. When using recirculation control, the extract air fan stops and a recirculation damper opens which allows the air to circulate through the unit. It is selectable whether or not the extract air fan should run during recirculation.

guide, revision F 16 During recirculation, offset SAF makes it possible to add to the supply air fan an offset to the setpoint during normal operation. If pressure control has been configured, the offset is set in Pa. If flow control has been configured, it is set in m3/h. If manual control has been configured, the offset is set in %. If you have selected the Offset function, which is a deviation from the regular supply air setpoint, you will instead be given the option to change this offset value here. Extra controller unit An independent temperature control circuit for control of for example after-heaters. The circuit can be configured to either heating or cooling.

Humidity sensor room Humidity control can be configured as either Humidification or Dehumidification or as combined Humidification/Dehumidification. Humidity sensor duct A duct humidity sensor is only used for maximum limitation function. Time settings General Corrigo has a year-base clock function. This means that a week-schedule with holiday periods for a full year can be set. The clock has an automatic summertime/wintertime change-over. Individual schedules for each week-day plus a separate holiday setting. Up to 24 individual holiday periods can be configured. A holiday period can be anything from one day up to 365 days. Holiday schedules take precedence over other schedules. Each day has up to two individual running periods. For two-speed fans and pressure controlled fans there are daily individual schedules for normal speed and reduced speed, each with up to two running periods. Up to 5 digital outputs can be used as timer controlled outputs. Each with individual week- schedules with two activation periods per day. These outputs can be used to control lighting, door locks etc. Only outputs which have been configured will be shown. Timer output 5 can be used to control a recirculation function. Time/Date This menu shows and permits the setting of time and date. Time is shown in 24-hour format. Date is shown in the format YY-MM-DD.

guide, revision F 22 Timer Normal speed There are 8 separate setting menus, one for each weekday and one extra for holidays. Holiday schedules take precedence over other schedules. For 24 hour running, set a period to 0:00 – 24:00. To inactivate a period, set the time to 00:00 – 00:00. If both periods of a day are set to 0:00 – 0:00, the unit will not run at normal speed that day. If you want to run the unit from one day to another, e.g. from Mon 22:00 to Tue 09:00, the desired running time for the various days must be entered individually. First Mon 22:00 – 24:00.... ...then Tue 00:00 – 09:00. Timer reduced speed These settings will be ignored if single speed fans are configured. Should periods for normal speed and periods for reduced speed overlap, normal speed takes precedence. Structure and function is otherwise identical with Timer Normal speed. Extended running Digital inputs can be used to force the unit to start although the timer says the running mode should be “Off”. For 2-speed fans and pressure/flow controlled fans, inputs for normal speed and reduced speed can normally be used. The unit will run for the set time. If the running time is set to 0 the unit will only run as long as the digital input is closed. Extra timer outputs 1…5 Up to 5 digital outputs can be used as timer controlled outputs. Only outputs which have been configured will be shown. Each with individual week-schedules with two activation periods per day. Each timer output has 8 separate setting menus, one for each weekday and one extra for holidays. Holiday schedules take precedence over other schedules. If the function Recirculation has been configured, Timer output 5 can be used for controlling start/stop of the Recirculation function.

The LED will continue to flash as long as there are unacknowledged alarms. Alarms are logged in the alarm list. The list shows type of alarm, date and time for the alarm and the alarm class (A, B or C alarm). To access the alarm list, press the alarm button, the front panel button with the red button- top. If there are multiple alarms, this is indicated by up / down arrow symbols at the right-hand edge of the display. Use the UP and DOWN buttons to access the other alarms. At the left end of the bottom display line the alarm status is shown. For active, unacknowledged alarms the space is blank. Alarms that have been reset will be indicated by the text Acknowledged. Still active or blocked alarms are indicated by the text Acknowledged or Blocked. Alarms are acknowledged by pressing the OK button. You are then given the choice of acknowledging the alarm or blocking the alarm. Acknowledged alarms will remain on the alarm list until the alarm input signal resets. Blocked alarms remain on the alarm list until the alarm has reset and the block has been removed. New alarms of the same type will not be activated as long as the block remains. Since blocking alarms can be potentially hazardous, you need a high log on authority to block alarms. Class A and B alarms will activate alarm output(s) if these have been configured. Class C alarms do not activate the alarm output(s). Class C alarms are removed from the alarm list when the alarm input resets even if the alarm has not been acknowledged. Free text If RIGHT is pressed once when the start menu is shown, a menu is shown in which it is possible to enter any text of your choice. This text can be used to show information concerning the commissioning company, name and phone number to service personnel etc. The easiest way to enter text is to use E tool©, but the buttons can also be used. Up to 4 lines of 20 characters each can be entered.

guide, revision F 26 Language If RIGHT is pressed three times when the start menu is shown, a menu is displayed in which the language can be changed. The different language files are stored in the application memory and are downloaded to the work memory. If a Corrigo has been reloaded with a program revision newer than the factory revision using E tool©, the controller will not allow language files to be downloaded from the application memory. This is because there is a risk that the language files are not compatible with the new revision. Therefore, you are limited to the two languages you have downloaded using E tool©. Indication LEDs Status indication can be found in the upper left corner of the controller. For controllers with display, the alarm indication and change mode LEDs are located in the keypad area. Status indication Changing the battery Corrigo has an internal battery to ensure the operation of the memory and real-time clock in the event of a power failure. When the alarm ”Internal Battery” is activated and the battery LED lights up red, the battery has become too weak and needs to be changed. Nonetheless, due to a backup capacitor, the controller will function at least 10 minutes without power supply. Since changing the battery requires knowledge of proper ESD protection, as well as dismantling and opening of the unit, this should be handled by skilled service personnel.
