2.1.2 Ventilation application The temperature controller is based on a supply air PI-controller for heating control with a preprogrammed set of control modes. A number of different control functions as well as analogue and digital in- and output functions can be bound to this controller. Certain functions are necessary, while others can be considered optional. The choice of which functions are to be used is free, the only restriction is the physical number of inputs and outputs of the different models.
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.

Chapter 3 Installation and wiring 3.1 Installation Corrigo can be mounted in a DIN-standard casing (minimum 9 modules), on a DIN-rail in a cabinet or, using a suitable front-mounting kit, in a cabinet door or other control panel. Ambient temperature: 0…50°C. Humidity: Max. 90 % RH, non-condensing. The picture below shows a wiring example for Corrigo E283W-3. 3.2.
3.2.2 Inputs and outputs The list of input and output functions in section 3.2.3 is a handy instrument to help you keep track of which inputs and outputs you will need to configure. Analogue inputs Analogue inputs must refer to an Agnd terminal placed in the same terminal block as the input being wired. Analogue inputs can, depending on the configuration, be used for either PT1000 temperature sensors or for 0…10 V DC analogue input signals, for example from a pressure transmitter.

Chapter 4 Commissioning General Before the Corrigo can be used, all inputs and outputs must first be configured, as well as all relevant parameters. All commissioning can be done using the Corrigo front panel display and buttons or using the external display unit E3-DSP. E tool© The best way however, is to configure the Corrigo by using E tool©. E tool© is a PC-based configuration program specially developed to simplify the commissioning of the Corrigo series.
Option 2: Read this manual in the order given below: The manual has been designed to act as a guide through the commissioning. The last chapters of the manual, not listed below, cover menus and functions that are not used during commissioning. Functional description Start by reading chapter 5. Functional description below. Some functions are essential to the working of the unit and must be included. Others are more of the nature of optional extras which can be excluded.
Manual/Auto Chapter 14. Learn to use manual control. A very useful tool for testing out and troubleshooting your system. Other functions Chapter 18. Alarm handling etc.
Chapter 5 Functional description 5.1 Temperature control General Corrigo has a choice of the following control modes: 1. Supply air control 2. Outdoor temperature compensated supply air control 3. Cascaded room temperature control 4. Cascade connected extract air temperature control 5. Outdoor temperature dependent switching between supply air control with outdoor temperature compensation and room temperature control 6.
Example: 0 % Cooling at HCOut = 30 % 100 % Cooling at HCOut = 0 % 0 % heat exch. at HCOut = 32 % 100 % heat exch. at HCOut = 50 % 0 % Heating at HCOut = 54 % 100 % Heating at HCOut = 100 % Output signal 100% 0% Controller signal 100% Cooling Heat exch. Heating 54% 50% 32% 30% 0% Heat demand In addition to these three, it is possible to connect two additional analogue output signals for control of optional sequences, Y4 extra sequence and Y5 extra sequence.
5.1.1 Control modes 1. Supply air control The supply air temperature is kept at the setpoint value by controlling the output signals for "Heating Y1", "Exchanger Y2", "Cooling Y3", "Extra sequence Y4" and “Extra sequence Y5”. A single PI control loop is used. A neutral zone can be set around the setpoint value. Example: If the setpoint is 18 °C and the neutral zone is 2 K, the cooling setpoint will be 19 °C and the heating setpoint will be 17 °C (FS=0 K).
6. Outdoor temperature dependent switching between supply air temperature control and extract air temperature control When the outdoor temperature is lower than a settable limit (winter), outdoor compensated supply air temperature control will be active, otherwise (summer) cascaded room temperature control as in control mode 4. 7. Outdoor compensated room temperature control The room temperature can be compensated when the outdoor temperature increases.
Frost protection The heater return water temperature is measured using the analogue input ”Frost prot.temp”. Low temperatures will generate an internal, proportional signal that is used to force the heating valve open thereby preventing freeze-up of the heater. The internal signal (“Internal signal”) will begin to rise as the frost protection temperature falls below “Alarm level” + “Prop. Band” in order to reach 100 % output when the signal has fallen to “Alarm level”.
Wiring suggestion high temp limit when using electric heating. Contactors are drawn inactivated. Note: It is important that the high temperature thermostat is hardwired to disconnect the power to the heater to ensure that the heating is shut down when the thermostat is activated even if the Corrigo should be faulty. 5.1.2.3 Water heating and electric heating The water heating is controlled by "Y1 heating", and the electric heating is controlled by the sequence "Split".
Deicing Deicing is activated either when the digital signal ”Deicing” is activated or when the value of the analogue input ”Deicing temp” falls below the de-icing limit (-3°C), or when the analogue signal ”Deicing pressure guard” rises above the set value for the current pressure. It is deactivated when the digital signal is reset, or alternatively when the analogue signal exceeds/falls below the limit value plus a settable differential.
Function to prevent the heat exchanger from freezing: A temperature sensor, exhaust air, outdoor air or extra controller sensor can be used as a prevention sensor. It is possible to set a starting temperature. This represents both the minimum time that the function should be active, the supply air fan (SAF) and extract air fan (EAF) compensation, as well as the minimum time before the next prevention cycle should begin. While the cycle is active, ”Deicing” is shown in the display and in E tool©.
5.1.4 Types of chillers Step controller Heating / DX cooling As alternative or complement to the above mentioned analogue control, heating and cooling can be activated in steps. The internal signal is then used to activate digital outputs for control of the heaters/chillers. Up to four heater outputs and three cooler outputs can be configured. There are two possible modes: Sequential control Each output step has individually settable on and off values in percent of the control signal.
DX cooling with exchanger control When running cascade control, the supply air controller setpoint is normally controlled by the room/extract air controller output signal. When DX cooling is activated, the supply air controller setpoint is lowered to five degrees (adjustable) below the setpoint given by the room/extract air controller. This prevents the DX cooling from being activated/deactivated too often.
Override of reduced speed for DX cooling Override to normal quantity of air for DX cooling when the unit runs on reduced quantity of air. The fans can be set to normal operation when cooling is required at high outdoor temperatures (e.g. >14°C, the same temperature limit as for blocking of DX cooling). 5.1.5 Support control Support control is normally used when room temperature control or extract air control has been configured. When extract air control is configured a room sensor must be installed.
If the outdoor sensor is located in the fresh air inlet duct and/or an extract air sensor is selected and ALL the start conditions are fulfilled, free cooling is activated and will run for 3 minutes to ensure that the temperature measurement when using an extract air sensor reflects the corresponding room temperature and that the outdoor temperature sensor senses the outdoor temperature even if it is placed in the fresh air inlet duct.
5.1.8 Enthalpy control Calculating the enthalpy means to calculate the energy content of the air, taking into consideration both the temperature and the air humidity. The value is given in energy per kilogram air (kJ/kg). If enthalpy control is configured, the enthalpy is calculated both indoors and outdoors. If enthalpy control is configured, enthalpy is calculated both outdoors and for the extract air.
5.1.11 Recirculation Recirculation is a function for distributing 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 (but can also be set to run) and a recirculation damper opens which allows the air to circulate through the unit. Recirculation is activated either via a digital input signal or by connecting it to "Timer output 5".
5.1.13 Extra temperature sensor The input signals ”Extra Sensor Temp 1”, ”Extra Sensor Temp 2”, ”...”, ”Extra Sensor Temp 5”, can be used to add extra temperature sensors for supervision of temperatures that are not related to any control functions. Each sensor has three alarms tied to it: High temperature, Low temperature and Sensor error. “Extra temperature sensor 1” should be used for external setpoint input. “Extra Sensor Temp 1” should be used for external setpoint input. 5.1.
If the maximum limitation is 80 % RH and the hysteresis is 20 % RH, the controller output signal will begin decreasing at 60 % RH. When halfway to 80 % RH (i.e. when at 70 % RH), half the output signal will be damped. If the humidity in the duct still reaches 80 % RH, the entire output signal will be damped. Dehumidification An analogue output is used to control a dehumidifier. The output will increase on increasing humidity. A digital output can also be used to start a dehumidifier.
This compensation can be made depending on supply air, extract air, room or outdoor temperature. It is possible to compensate either one or both of the fans at the same time. It is possible to set which fan should then be compensated, the supply or extract air fan. Crosswise interlock Crosswise interlock of fans can be configured, which e.g. means that if one fan stops, the other fan will also stop.
Extra compensation curve As a complement to the above outdoor compensation, there is a function called ”Extra compensation curve pressure/flow setpoint” which can be used to set a compensation based on the room, extract air, supply air or outdoor temperature. The curve has three parameter pairs which correspond to the value of the compensation at three different temperatures.
The compensation can be selected to apply to both normal and reduced speed, or for normal speed only (factory setting = both speeds). Extra compensation curve As a complement to the above outdoor compensation, there is a function called ”Extra compensation curve” which can be used to set a compensation based on the room, extract air, supply air or outdoor temperature. The curve has three parameter pairs which correspond to the value of the compensation at three different temperatures.
Frequency control EAF with SAF slave The rotational speed of the extract air fan is controlled by a pressure transmitter which is placed in the extract air duct. The supply air fan has no pressure transmitter. Instead, the supply air fan output is made to follow the extract air fan control signal. A scaling factor can be added if the supply air fan characteristics are not the same as the characteristics of the extract air fan (only pressure control of the extract air fan is possible using this function).
Minimum limit For frequency controlled fans an adjustable minimum limit can be set individually on the supply air and extract air fan control signals.
When used with 2-speed fans they will start using reduced speed when the CO2 value rises above control value one and switch to normal speed when the CO2 value reaches control value two. The fans will stop when the CO2 value falls 160 ppm below control value one. If demand controlled ventilation is activated in combination with mixing dampers, and the CO2-value rises above the setpoint value, the dampers will let in more outdoor air. The function is controlled by a PI-controller. See section 5.1.
5.4.3 Extra control for external motor External control of an external (fan) motor can be configured. The fan is started via either a digital input or a time channel. A digital output activates the (fan) motor. A digital input is available for run time indication/motor protection. Inputs and outputs Motor control 1 DI DI Motor control 1 indication DI Motor control 2 DI Motor control 2 indication DO Motor control 1 start DO Motor control 2 start 5.
In- and outputs Heating Exch. Cooling Outdoor temperature sensor AI DO DO DO Start/stop circulation pump DI DI DI Run ind/alarm, circ. pump 5.6 Damper control 5.6.1 Close-off dampers The outdoor air and exhaust air ducts close-off dampers can be controlled by digital outputs or be hard-wired to the supply air fan relays for normal and reduced speed in such a fashion that the damper is open when the supply air fan is running.
DO Outdoor air damper DO Exhaust air damper DO Fire damper DI Fire alarm DI Fire damper end switch monitoring 5.7 Extended running and External switch The digital inputs for extended running can be used to force the unit to start although the timer says the running mode should be “Off”. Normal running always takes precedence over reduced speed. "Extended Operation, Normal" takes precedence over the timer output for reduced speed.
Stop function Each alarm offers the possibility to choose whether an activated alarm should stop the controller or not. The controller can also be set to run at reduced speed during alarms. The latter option can only be configured using E tool©. Automatic restart will take place when the alarm has been acknowledged. For some alarm types such as electric heating high temperature limit and water heating frost protection it would be dangerous to not stop the unit on alarm.
Chapter 6 Starting and stopping the unit 6.1 Start conditions The unit will be started and will run when any one of the following conditions is met: 1. Timer output for normal speed or timer output for reduced speed is ON 2. The unit is started manually using the Corrigo front panel or via E3-DSP 3. Digital input for extended running is activated 4. Support control is activated and the present room temperature is higher/lower than the preset starting value (Support heating/cooling) 5.
6.3 Start sequence Start of the unit will run according to the following sequence: 1. If the controller is configured for water heating and has an outdoor temperature sensor and the outdoor temperature is below +3ºC the heating valve is opened and the heating circulation pump is started. 2. If the controller is configured with a heat exchanger and has an outdoor temperature sensor and the outdoor temperature is below +15ºC the heat exchanger will be run at 100% capacity for a pre-set time. 3.
Chapter 7 Display, LEDs and buttons This section is applicable to Corrigo units with display and buttons but also to the hand terminal E3DSP which can be connected to Corrigo units without display and buttons. Room units are available with or without display, or as a touch display (see instructions and product sheets for ED-RU..., ED-RU-D... and ED-TCV). 7.1 Display The display has four rows of 20 characters and is backlit.
Regulator vent. sys 2008-11-20 13:30 System: Running Sp: 18.0 Act: 18.2°C Pressing DOWN will move you through the menu choices at this, the lowest level. UP will move you back through the choices. Which menus are shown depends on which access level you are using (see chapter eight for more information about logging on to higher levels).
Chapter 8 Access rights Running mode Temperature Time settings Access rights There are four different access levels. The Admin level has the highest access, while the Service, Operator and basic “no-log on” level have the lowest. The choice of access level determines which menus are shown, as well as which parameters can be changed in the displayed menus. Admin level gives full read/write access to all settings and parameters in all menus.
8.3 Change password As default Corrigo comes with the following passwords for the different levels: Admin Service Operator Normal 1111 2222 3333 5555 You can only change the password for log on levels lower or equal to the presently active level, i.e. if you are logged in as Admin you can change all passwords, but as Operator you can only change the Operator and Normal passwords. There is no point in changing the Basic password since access to that level is granted automatically to all users.
Chapter 9 Running mode Running mode Temperature Time settings Access rights Collected here are a number of menus showing running mode, selected functions, alarm events and status of inputs and outputs.

Chapter 10 Temperature Running mode Temperature Time settings Access rights 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. The below menus are available, providing the corresponding input has been activated. Setpoints are available with a separate value for reduced speed. This is achieved using a temperature offset when the unit runs in reduced speed.
Outdoor comp setp 10.0°C = 18.0°C 15.0°C = 18.0°C 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. Example: At the lower end the setpoint is increasing by 1°C for every 5 °C lowering of the outdoor temperature. So the setpoint at –23°C would be 25°C + .6x 1.0°C = 25.6°C. Setpoint.

Chapter 11 Air control Pressure control SAF and EAF Pressure control can be entered in pascal (Pa) or inch water gauge (in.wg.). A factor (x100) is used in both the program and display when the unit “in.wg.” has been selected. When using pressure or flow controlled fans, the setpoint can be temperature compensated. The compensation has the default value 0 Pa, i.e. no compensation is added. The compensation is linear between the setting points. The compensation can be positive or negative.

Two humidity sensors can be connected, a room sensor for control and an optional duct sensor for maximum limiting. The limit sensor can be omitted. The humidity control is handled by a PI-controller. The humidity sensors must give 0…10 V DC for 0…100 % RH. Humidity sensor room Humidity room Actual: 51.9% RH Setp: 50.
Chapter 13 Time settings Running mode Temperature Time settings Access rights 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.
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 both days must be entered. Normal speed Monday Per 1: 07:00 – 16:00 Per 2: 22:00 - 24:00 Normal speed Tuesday Per 1: 00:00 – 09:00 Per 2: 00:00 - 00:00 13.3 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.
13.6 Holidays Up to 24 separate holiday periods for a full year can be set. A holiday period can be any number of consecutive days from 1…365. The dates are in the format: MM:DD. When the present date falls within a holiday period, the scheduler will use the settings for the weekday “Holiday”.
Chapter 14 Manual / Auto General In this menu the running mode of all the configured output signals and a number of control functions can be manually controlled. This is a very handy feature which simplifies the checking of individual functions in the Corrigo. The running mode for the whole unit is set in the menu "Running mode". See section 9.1. The supply air controller's output signal can be manually set (Manual/Auto) to any value between 0 and 100 %.
