Chapter 1 About the manual This manual covers all the models in the Corrigo series used with the ventilation application. This revision covers program revisions from 3.3. More information More information about Corrigo can be found in: Corrigo ventilation user guide – A simplified manual Manual E tool© – Manual on how to configure the controllers using the PC software E tool©, available in Swedish, English, German and French.
Chapter 2 About Corrigo The Corrigo series comprises three model sizes: 8, 15 or 28 in-/outputs. In each third generation model Corrigo, all applications are loaded in a separate memory area. The models have article number E...-3 (where 3 stands for third generation). A new feature in version 3.3 are models with three communication ports. The 3 port Corrigo models have article number E...3-3 (where the initial “3” stands for 3 ports). For more detailed information, see chapter 16.
2.2 Application choice On delivery, the main memory in the Corrigo is empty. All the application programs that can be run in the Corrigo are located in a separate memory area. On the first start-up, the controller will start a special program for downloading a suitable application to the main memory. For certain customised models, an application has already been selected when the product is delivered. If so, the selected application will be started immediately.

2.2.2 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 Wiring 3.2.1 Supply voltage 24 V AC ±15%, 50…60 Hz or 21…36 V DC If Corrigo and its connected actuators share the same transformer, it is essential that the same transformer pole is used as reference for all the equipment. The equipment may otherwise not function as intended and may also suffer damages. 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.
All the digital outputs are controlled by MOSFET transistors. The outputs are internally connected with G0 and can deliver max 2 A per output. However, the total power for all the DOs must not be over 8 A. A number of different wiring alternatives are possible depending on the type of supply voltage to the Corrigo and the relay type.

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. Very useful 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 anologue 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. For example, if the setpoint is 18°C and the neutral zone is 2K, the setpoint for cooling will be 19°C and the setpoint for heating will be 17°C (FI = 0K).
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”.
Contactors 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". Split (see the section Split of optional temp sequence) must always be set to "Heating".
Deicing De-icing is activated either when the digital input signal ”De-icing exchanger” is activated or when the value of the analogue input ”Deicing temp” falls below the deicing limit (-3°C). It is deactivated when the digital input is reset or the analogue input rises above the limit value plus a settable differential.If a differential pressure switch is used in addition to the heat exchanger, the digital input ”Deicing thermostat exchanger” is also used.
CO2 If demand controlled ventilation (see 5.4.2) 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. Factory settings: P-band 100ppm and I-time 100 seconds. These values can only be changed in E tool©. CO2/VOC control can be used on ”Y2 exchanger” or ”Y4 extra sequence”. The control is selectable for use on Y2, Y4 or on both outputs.
1 Y1 = 1 2 1 1 4 2 1 Step controllers and Change-over The digital output signals "Heating/cooling step 1", "Heating/cooling step 2" and "Heating/cooling step 3" are used for step controllers during change-over control (see section 5.1.12). They have the same functions as other step controller outputs, but are set to either heating or cooling depending on whether heating or cooling is required.
When two DX cooling steps are used with binary function, the cooling effect is divided into three steps. The desired blocking level can be set individually for each of these steps. When three DX cooling steps are used with binary function, the cooling effect is divided into seven steps. However, the controller still only has three blocking level settings. Therefore, Blocking step 1 will apply to binary steps 1 and 2, Blocking step 2 to binary steps 3 and 4, and Blocking step 3 to binary steps 5, 6 and 7.
Support control heating Demand for support control heating is when the room temperature is lower than the start value which is settable 0 to 30°C. The fans will run at the preset speed, the heater and the heat exchanger are controlled by the supply air temperature controller with the configured max limitation for the supply air (FS=30°C) as setpoint and the cooling is shut off (0%).
In- and outputs Outdoor temperature sensor or Intake temperature AI AI Room sensor or Extract air sensor DO Free cooling operation 5.1.7 Cooling recovery If the cooling recovery has been configured, there is a cooling requirement and the extract air temperature is a settable amount lower than the outdoor temperature, cooling recovery can be activated. When cooling recovery is activated the heat exchanger signal will be reversed to give increasing recovery on increasing cooling demand.
5.1.9 Heat exchanger efficiency monitoring General The function calculates the heat exchanger temperature efficiency in percent when the output signal to the exchanger is higher than 5 % and the outdoor temperature is lower than 10°C. When the control signal is lower than 5 % or the outdoor temperature is higher than 10°C the display will show 0 %.
The recirculation setpoint can be configured as constant or offset. Constant means that the recirculation setpoint will be used. Offset is based on an offset from the supply air setpoint. To lower the temperature, it is possible to configure free cooling to be used during recirculation, if the conditions for free cooling are fulfilled. Then, the recirculation damper closes, the supply and extract air dampers open and the extract air fan starts (the supply air fan also starts, if it is not already running).
The extra controller can also be used for humidity control. The cooling battery will be used for dehumidification if the room/extract air humidity is too high. The function uses the sensor “Extra unit temp” and is placed immediately after the cooling battery. The function also requires use of a room humidity or extract air humidity sensor. Example: If the room humidity exceeds the setpoint for the function, the cooling battery will be controlled by the external controller. The heater is controlled normally.
Digital humidity signal A digital output signal, "Dehumidification/Humidification", can be used for on/off control of humidifiers/dehumidifiers. The output signal has an activation value and a deactivation value which are connected to the humidity controller output. The signal is activated when the humidity controller output rises above the set activation value and is deactivated when the humidity controller output drops below the set deactivation value.
The extract air fan and the supply air fan have individual start and stop delays which are normally set so that the extract air fan is started before the supply air fan. If there are not enough digital outputs for individual control, both fans will have to be started using the signal for the supply air fan, and the delay be created using an external time relay. 5.4.

The value from the pressure transmitter is recalculated to a volume flow using the formula below and the fans will be controlled to give a constant flow.

The rotational speed is selected by setting a fixed output signal (0 – 100%). Values for normal and reduced speed can be configured for each fan.
Frequency control EAF with flow control SAF 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 is controlled by the extract air duct flow in order to achieve a balanced ventilation. A pressure transmitter placed in the extract air fan cone (“Extra SAF Pressure”) provides a measurement of the current extract air flow.
When the function is activated and combined with pressure controlled fans and the CO 2 value rises above control value one the fans will start at reduced speed, if they are not already running. Should the CO2 value continue to rise the fan speed will also increase until the CO 2 value reaches control value two at which point the fans will be running at normal speed. The fans will stop when the CO 2 value falls 160 ppm below control value one.
The function has a settable minimum running time. In- and outputs CO2 sensors AI 5.4.3 Extra control for external motor External control of an external (fan) motor can be configured. The fan is started either via a digital input or via a time channel. A digital output activates the (fan) motor. A digital input is available for run time indication/motor protection.

In- and outputs Outdoor air damper DO 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”.
Alarm priorities Alarms can be given different priority levels, A-alarm, B-alarm, C-alarm or not active. Digital outputs can be bound to act as alarm outputs for A-alarms or B/C-alarms or both A- and B/C alarms. The digital outputs can be inverted, so that an inoperative alarm gives a high output and vice versa. A- and B-alarms must be acknowledged to reset. C-alarms automatically reset as soon as there is no longer a cause for 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.

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 -5.0°C 0.0°C 5.0°C comp setp = 23.0°C = 22.0°C = 20.0°C 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.

Chapter 11 Air control Pressure control SAF and EAF Pressure control can be set in pascal (Pa) or in inch water gauge (in.wg). A factor (x100) is used in the program and displays when the unit is set to in.wg. 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 %.
