2 Introduction to Corrigo
The Corrigo series of controllers are used for ventilation control. They can be used as a stand-alone controller or integrated in a SCADA system.
There are two versions of the Corrigo with different hardware platforms: The 24 VCorrigo Ardo and the 230
V Corrigo Vido (see more in:
chapter 3.1 Display, LED:s and buttons
)
Corrigo has between 15, 20 and 28 I/O:s depending on hardware and model.
2.1 Display
The Corrigo Ardo is available with or without display. The Corrigo Vido is only available with display.
An external display can be connected to the controller to make it possible to monitor and work with the controller from another location.
The display or the external display is used to e.g. change values, set timers and monitor alarms.
2.2 Application tool and Configuration of Corrigo
Application tool is a PC-based, free configuration software tool, available at Regin's website www.
regincontrols.com
. The tool is used to configure and commission the controller .
The controller doesn't need to be connected to the computer while configuring. All settings are made in the tool and then uploaded to the controller.
An infinite number of configurations can be stored in the computer memory for later use.
A communication cable is required in order to upload the configuration to the controller. The controller must also be powered up and the application selected in order for it to be configured.
Predefined configurations can be downloaded as atf-files from Regin’s website, www.regincontrols.com
.
These atf-files can be opened in the tool and synchronized to the controller.
More information about configuration is available in:
chapter 5.3 Configuration - System
2.3 Internal web interface
When the Corrigo is connected to an external display or computer with a browser and a connection to the internet, an internal web interface will be shown. The web interface can be used to change setpoints, configure and monitor the controller.
8 (196) Corrigo manual, Rev. D
Figure 2-1 Start screen for the web interface
2.4 Comparison between the user interfaces
There are different user interfaces that can be connected to the Corrigo.
The text-displays and the touch screen ED-T43L-V are designed as an end-user interface to show current values, adjust setpoints and timer settings and to adjust settings like limits of control functions and the PIDsettings.
The complete configuration can only be done via Application tool or the web-interface.

4.1 Function overview
A number of different control functions as well as analogue and digital in- and output functions can be found in 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. Information about configuration for the different functions is found in
5 Information for the specialist - 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
✓ Extract air depending supply air temperature
With control of:
✓ Heat exchangers (liquid connected, plate or rotating)
✓ Mixing dampers
✓ Heating coil (water with or without frost protection, electric with high temperature limit switch, DX or combi coil)
✓ Cooling (water, DX with or without exchanger control)
✓ Circulation pumps
Fan control
✓ 1-, 2- or 3-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
It is possible to use either humidification or dehumidification, or to use combined humidification and dehumidification.
Timer control
For starting and stopping the unit, annual clock function. Up to 4 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 CO
2 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.
Corrigo manual, Rev. D 31 (196)
Information for the specialist - Function descriptions
Free cooling
When this function has been activated, it is used during the summer to cool the building during the night using cool outdoor air, thereby reducing the need to run chillers 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 .
Enthalpy control
Measures and compares the energy content (enthalpy) of the outdoor air and the extract air (temperature and air humidity). When this function is active, the mixing damper signal will be overridden to recirculation if the enthalpy is higher outdoors 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
There are 2 equal step controllers. Both controllers will have 4 steps and can be configured as sequential control or binary 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.

4.2 Temperature control
4.2.1
General
Corrigo has a choice of the following control modes:
1. Supply air
2. Supply air outdoor compensated
3. Room cascade
4. Extract air cascade
5. Room (summer) else outdoor compensated supply air
6. Extract air (summer) else outdoor compensated supply air
7. Room outdoor compensated
8. Extract air outdoor compensated
9. Extract air dependent supply air
The supply air temperature controller is reverse acting, i e. the output will increase for decreasing temperature. The controller is a PID-controller with settable P-band, I-time and D-time.
Figure 4-1 Application tool menu path to temperature control
In the first mode, the temperature at the supply air sensor will be constantly kept at the user setpoint value.
In the second mode, the supply air temperature setpoint is adjusted depending on the outdoor temperature.
In modes three and four the supply air is controlled as part of a cascade controller together with the room/ extract temperature controller. The room/extract temperature offset will dictate the supply air temperature setpoint.
Mode five and six vary according to the outdoor temperature: Outdoor temperature compensated supply air control, as in mode two, in winter and cascaded room control or cascaded extract air control in summer, as in modes three or four. The switch-over temperature is settable.
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). If the supply air temperature is in the neutral zone, the heating and cooling will be blocked. If the supply air temperature decreases below the setpoint –NZ/2 the heating signal will be active until setpoint is fulfilled. If the supply air temperature increases above the setpoint +NZ/2 the cooling signal will be active until setpoint is fulfilled.

Freeze protection
The heater return water temperature is measured using the analog input Freeze protection temperature 1…3 or the digital input Freeze protection guard , depending on the selection of freeze protection ( Configuration ►
Heater (Sequence A) ► Type of freeze protection ). 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 will begin to rise as the frost protection temperature falls below the Alarm limitation running mode + P-band running mode in order to reach 100 % output when the signal has fallen to Alarm level .
When the internal signal reaches 100 % or the digital input Freeze protection guard is activated, the unit is shut down, the heating output is set to completely open mode and an alarm is activated. .

DX cooling
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.

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.
If the supply air temperature falls below the setpoint given by the room/extract air controller, the heat exchanger output will be activated in order to try to maintain the supply air setpoint given by the room/ extract air controller. The output uses P-control with a P-band of half the setpoint lowering (adjustable, 2.5°
C as default). The setpoint given by the room/extract air controller cannot drop below the set min limit.
When there is no longer a cooling demand, the supply air controller setpoint will return to the value given by the room/extract air controller.
Example:
The room controller gives a supply air setpoint of 16°C. If there is a cooling demand, the supply air controller setpoint is lowered to 11°C (16 – 5) and DX cooling is activated. Should the supply air temperature fall below 16°C, the exchanger output will be activated and reach 100 % output when the supply air temperature has fallen to 13.5°C (16 - 2.5).

Blocking of DX cooling at low outdoor temperature
DX cooling can be blocked when the outdoor temperature is low. It is possible to block the four cooling steps individually or to block all DX cooling. The temperature limits are adjustable (+13°C default) and have a fixed one degree hysteresis.
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 four blocking level settings. Therefore, Blocking step 1 will apply to binary steps 1 and 2, Blocking step 2 to binary steps 3 and 4, Blocking step 3 to binary steps 5, 6 and Blocking step 4 to binary steps 7.
When four DX cooling steps are used with binary function, the cooling effect is divided into fifteen steps.
However, the controller still only has four blocking level settings. Therefore, Blocking step 1 will apply to binary steps 1-4, Blocking step 2 to binary steps 5-8, Blocking step 3 to binary steps 9-12 and Blocking step 4 to binary steps 13-15.

Blocking of DX cooling at low supply air fan speed
When DX cooling is used in conjunction with pressure controlled or flow controlled fans it is possible to block DX cooling if the supply air fan control signal falls below a preset values. For sequential control, the blocking level is individually settable for each DX cooling step.
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.

Sequence Fan setpoint compensation
The fan setpoint compensation is used to integrate the fans into the temperature control sequence for heating or cooling. The speed of the fans can be increased or decreased depending on the signal of the temperature control loop. ( Application tool ► Configuration ► Functions ► Sequence x ► Type of setpoint compensation ). The output signal of the sequence acts directly on the calculated setpoint of the fans but can also be output additionally via configured outputs. The maximum compensation is adjustable via a parameter ( Ventilation ► Temperature control ► Selected sequence ► Max fan compensation (% )).

Change-over
Change-over is a function for installations with 2-pipe systems. It makes it possible to use the same pipe for both heating and cooling, depending on whether heating or cooling is required.
Change-over functions can be used for control of reversible heat pumps or external change-over coils.
There are two different change-over functions with two different analog output signals Change-over 1 and
Change-over 2 , that is used for change-over control.
Switching between heating and cooling can be done in two ways. Open contact gives heating control and closed contact gives cooling control.
If the input has not been configured, change-over is handled by the internal controller signal. The output signal will follow the two sequence output signals Change-over sequence for heating and Change-over sequence for cooling .
If frost protection sensor has been configured, it will function in the usual way when heating is active.
However, when cooling is active, it will only be used for indicating temperature.

Step controller
Step controller heating / cooling
As an alternative or complement to analog control, heating and cooling can be activated in steps. The internal signal is then used to activate digital outputs for control of the heaters/coolers. Two step controllers with up to four step outputs can be configured in Application tool.There are two possible modes; Sequential control and Binary control .
Sequential control
Each output step has individually settable on and off values in percent of the control signal. The number of steps is equal to the number of heater/cooler groups. Minimum on and off times can be set, i.e. the minimum time the step has to be inactive or active for a change to occur. An analog output signal can also be used to fill out between the steps. The signal will go 0…100 % between the activation of each step
Binary control
The heater power outputs should be binary weighted (1:2:4:8 same for heating and cooling). The number of steps to be controlled is set in Configuration ► Functions ► Step controller 1/2 ► Number of steps . After that, the program will automatically calculate the individual activation levels. Switching differential and minimum on/off times can be set in Ventilation ► Temperature control ► Step controller 1/2 ► Min switch time, Step x start point, Step x stop point . The number of heating/cooling steps will be: 2 no. of groups -1. In binary mode, the analog output signal ( Step controller 1 / 2 ) may also be used to fill out between the steps. The signal will go 0…100
% between the activation of each step. The load connected to the analog signal should have the same size as the smallest of the binary groups. In the example below there are 4 heater groups (1:1:2:4) and the total number of heating/cooling steps is eight.

Support control
Support control is normally used when room temperature control or extract air control has been configured.
Extract air control
When extract air control is configured a room sensor must be installed.
Support control Heating or Support control Cooling will run if support control is configured, the running mode is in Off-state (timer control OFF and not in extended running) and if conditions call for support control (see below). Minimum run time is settable 0 to 720 minutes (FS= 20 minutes) ( Ventilation ► Demand control ► Support control ► Min time for support control ).
Supply air temperature control
Support control can also be configured when supply air temperature control is used, if a room sensor is installed. The controller uses the configured min. (FS=15°C) and max. (FS=30°C) limitation values as support control setpoints ( Ventilation ► Demand control ► Support control ). The values can be changed in
Ventilation ► Actual/Setpoint ► Supply air controller ► Min limit supply air, Max limit supply air.

62 (196) Corrigo manual, Rev. D
Information for the specialist - Function descriptions
Support control can also be configured to start only with the supply air fan. In this mode, the extract air fan is not active. This requires a digital output to be configured, which controls the recirculation damper to open completely so the supply air fan can circulate the air to and from the room. The digital output is called
Recirculation air damper ( Configuration ► Digital Outputs ).
Active support control for sequence
It’s also possible to configure the output value when support control is active (same settings as for recirculation) for each sequence. The sequence output can be configured to 0%, 100% or Auto (modulating

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 ( Ventilation ► Demand control ► Support control ). 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%). Support control heating stops when the room temperature rises to the stop value and the minimum run time has been exceeded or the running mode changes to On .
For each sequence it’s also possible to configure the output value when support control heating is active. The sequence output can be configured to 0%, 100% or Auto (modulating 0-100%) (See section
for more details).
Support control cooling
Demand for support control cooling is when the room temperature is higher than the start value which is settable 20 to 50°C ( Ventilation ► Demand control ► Support control ). The fans will run at the preset speed, the heater and the heat exchanger (cool recovery is active) are shut down (0 %) and the cooling is controlled by the supply air temperature controller with the configured minimum limitation (FS=12°C) as setpoint.
Support control cooling stops when the temperature falls below the stop value and the minimum run time has been exceeded or the running mode changes to On .
For each sequence It’s also possible to configure the output value when support control cooling is active. The sequence output can be configured to 0%, 100% or Auto (modulating 0-100%) (See section
for more details).

4.3.9
Free cooling
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.
Free cooling requires an outdoor sensor or an intake temperature sensor and either a room sensor or an extract air sensor. If both outdoor sensor and intake sensor is configured it uses the outdoor sensor for the function.
Free cooling is only activated when all the start conditions below are fulfilled:
✓ Less than four days have passed since the unit was last in running mode.
✓ The outdoor temperature during the previous running period exceeded a set limit (22°C).
✓ It is between 00:00 and 07:00 in the day (settable).
✓ The timer outputs for Normal speed , Extended running, Normal and External switch are Off .
✓ A timer channel will be On sometime during the next 24 hours.
✓ The outdoor temperature is a settable difference (FS=2°C) lower than the room/extract temperature
( Ventilation ► Demand control ► Free cooling ► Start when extract-outdoor > (°C) ).
If an intake sensor is used 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 (settable) to ensure that the temperature measurement when using an extract air sensor reflects the corresponding room temperature, and that the intake temperature sensor senses the outdoor temperature even if it is placed in the fresh air inlet duct. If an outdoor sensor and a room sensor is selected, the unit will not start free cooling as long as all the temperatures are not within the start and stop temperature intervals.
After three minutes (settable), the stop conditions will be controlled.
Stop conditions:
✓ Outdoor temp above the set max. value (18°C) or below the set min. value (condensation risk, 10°C).
✓ The room temp/extract air temp. is below the set stop value (18°C).
✓ Difference between extract/room and outdoor temperature rises above the settable difference (FS=2°
C) - a hysteresis of 0.5 °C.
✓ The timer outputs for Normal speed , Extended running, Normal or External switch are On .
✓ It is past 07:00 in the day.
If any stop condition is fulfilled after three minutes, the unit will stop again. Otherwise, operation will continue until a stop condition is fulfilled.
If the unit is stopped due to outdoor temperature is outside the temperature intervals the unit will start again after 60 min (settable), it will not start again if room/extract air temp has reached below the stop value.
When free cooling is active, the fans run at normal speed or the set value for pressure/flow control. An offset can also be entered for the fan setpoints during free cooling. The digital output Free cooling indication is active. All sequence A to J outputs are shut down. After free cooling has been active, the heating output is blocked at start up for 60 minutes (configurable time).

When the control signal is lower than 5 % or the outdoor temperature is higher than 10°C the display will show 0 %.
If an intake sensor is configured it will use that for the outdoor temperature.
The heat exchanger efficiency is calculated using the following formula:

4.3.14 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 Extra time channel 4
(Application tool ► Time control). If a timer output for Low/Normal/High speed is activated during recirculation via Extra time channel 4 , Low/Normal/High speed gets priority. If a timer output for Low/
Normal/High speed is activated during recirculation activated by a digital input, recirculation gets priority.
Corrigo manual, Rev. D 67 (196)
Information for the specialist - Function descriptions
Either a digital output ( Recirculation damper ) or an analog output sequence A to J can be used as an on/off output signal.
Recirculation control can be configured as either air circulation ( temperature control inactive ) or air circulation with temperature control. (Only heating, only cooling or both heating and cooling). Recirculation control has its own setpoint. However, the other settings are the same as for normal operation, i. e. if normal operation has been configured as room control, room control will also be used during recirculation.
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, see
. Then, when 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. If the free cooling function is not configured for recirculation control and you want to cool down the supply air via a low recirculation setpoint, the cooling battery will be used.
A max. room temperature can be configured for recirculation control under Ventilation ► Demand control ►
Recirculation . If the room temperature rises above the set value, recirculation will be stopped. When the room temperature has fallen 1 K below the set max limit, recirculation will start again if the start conditions are still fulfilled.
When running frequency controlled fans and using recirculation control you can, depending on the type of fan control, configure a special pressure/flow offset for the setpoint or a manual output signal for the supply air fan ( Ventilation ► Fan control ► Fans ► Offset ... fan when recirculation) .
It’s also possible to configure the output value when recirculation is active for each sequence. The sequence output can be configured to 0%, 100% or modulating 0-100%.

4.4 Fan control
4.4.1
General
The variable speed of the fan is controlled via a frequency converter.
Variable speed control uses an analog output per fan or Modbus communication for controlling a frequency converter. There is one setpoint for each fan for normal, low and high speed. Pressure or air flow control can be used, the offset is in the configured unit (pressure/flow/percent).
Variable speed fans can also be configured to be run with fixed output values (0-100%).
Timer outputs
The fans are normally controlled by the timer channels for slow, normal and high speed but can also be started via a digital input or communication.
Slow, normal and high speed
The units will always start directly with the desired speed.
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 will be created using an external time relay.
Speed limits
For both supply air and extract air fans the max and min speed limit will be applied to the output. If the user sets the speed value manually or if the ventilation system stops, this will override the set fan speed limits.
Fan control types
There are different types of fan control. The control type is selected in Application tool ► Configuration ►
Functions ► Function activation ► Fan control type. See
below for a description of the different types.
Table 4-48 Fan control types
Pressure
Flow
Control of the fan speed using pressure transmitters.
Instead of giving a pressure setpoint value, it is possible to use an airflow volume value in m 3 /h. The value from the pressure transmitter is recalculated to a volume flow and the fans will be controlled to give a constant flow.
Manual
External
Use the manual setting if you want to manually set the speed of the fan
Use the external setting if you have an external device that controls the fan speed, e.g. 0…10 V device.
Supply air pressure and extract air fan slave The speed of the supply air fan is controlled by a pressure transmitter which is placed in the supply air duct. The extract air fan does not have a pressure transmitter, instead you let the output for the extract air fan follow the control signal for the supply air fan. A scaling factor can be added if the characteristics of the extract air fan are not the same as the characteristics of the supply air fan. (Only pressure control of the supply air fan is possible using this function.)
Supply air pressure with extract air flow slave The speed of the supply air fan is controlled by a pressure transmitter which is placed in the supply air duct. The extract air fan is controlled by the supply air flow, in order to achieve a balanced ventilation. A pressure transmitter which is placed in the supply air fan cone ("SAF flow") gives a measured value of the present supply air flow. A corresponding pressure transmitter is placed in the extract air fan cone and gives a measured value of the extract air flow.
The supply air flow is the setpoint used for control of the extract air fan. A scaling factor can be added if the extract air fan does not have the same characteristics as the supply air fan.
70 (196) Corrigo manual, Rev. D

Table 4-48 Fan control types (continued)
Extract air pressure with supply air fan slave The 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).
Extract air fan pressure with supply air flow slave
The 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 (“EAF flow”) provides a measurement of the current extract air flow. A corresponding pressure transmitter is placed in the supply air fan cone, providing a measurement of the supply air flow.
The supply air fan is controlled using the extract air flow as a setpoint. A scaling factor can be added if the supply air fan does not have the same characteristics as the extract air fan.

Compensation curve
When running pressure/flow control or manual frequency control, it is possible to for the pressure/flow or output to be compensated. By using compensation, the fan can be run at low speed more of the time. The fan speed will increase only when necessary, thus saving energy.
This compensation can be made depending on any analog input such as supply air, extract air, room, outdoor temperature, humidity, CO
2 etc. There are three equal compensation functions.
It is possible to compensate either one or both fans at the same time. It is possible to set which fan that should be compensated, the supply or extract air fan.
There are three compensation functions called Fan compensation curve 1…3 which can be used to set a compensation based on the configured analog input signal (temperature, pressure, flow humidity, CO
2
). 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 fans or one fan, to low, normal, high or all speeds or only when defrosting.
When configuring in Application tool, you select the following settings for the compensation curve:

Timer outputs
The fans are normally controlled by the timer channels for low, normal and high speed but can also be started via digital input or communication. (Application tool ► Time control)
Fan levels
A frequency controlled fan is the only type of fan that works with the Corrigo. The fan can be set to Low,
Normal or High speed. The selection of the fan speed defines which IOs and time channels will be active in the application.
The fans will always start directly with the desired speed.
There are four different fan speed levels to choose from in Application tool:
✓ Normal
✓ Low - Normal
✓ Normal - High
✓ Low - Normal - High
Variable speed control uses an analogue output per fan or Modbus communication for controlling a frequency converter.
For more information about frequency converters, see
Appendix F Frequency converters and EC controllers for heat exchangers
The fans are normally controlled by the timer channels for slow, normal and high speed but can also be started via digital input or communication.
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 will be created using an external time relay.

Fan control types
Pressure
During pressure control, two separate analog output signals are used for supply and extract air and two separate analogue input signals for supply and extract air for pressure transmitters. The fan speeds are controlled via frequency converters, thereby maintaining constant pressure. The pressure transmitter inputs are scalable using Min input (V) and Max input (V).
A digital output signal is normally used for each fan ( Supply air fan start/step 1 and Extract air fan start/step 1 ) for sending a start signal to the frequency converters. The start signal is activated as long as the fan is expected to be running and the control signal is > 0%.
For the supply and extract air fans, there is one individually settable value for normal speed, for low and high speed. Changing between the speed setpoint values is done using the timer channels or using digital input signals ( Extended Operation low/normal/high speed ).

Flow
Instead of giving a pressure setpoint value, it is possible to use an airflow volume value in m 3 /h. 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.
Flow = K * ΔP X
K and X are settable constants depending on the fan size.
Δ P is the differential pressure over the fan in Pa.
Each fan has its own set of parameters.
X is normally 0.5 indicating that the flow is proportional to the square root of the differential pressure.

Manual
Manual control of the fan is set in Ventilation ► Manual/Auto .
Frequency controlled fans can be controlled at a fixed rotational speed. The rotational speed is selected by setting a fixed output signal (0 – 100%). There is one individual setpoint value for normal speed, for low speed and high speed.
Fans that are run with a fixed output signal can also be compensated (see the section above). In this mode, pressure sensors are not needed.
External
This signal can be used to control the SAF and EAF flow setpoints from an external VAV system if the
”Frequency control external” fan type is used.
If this signal is configured as an analog input signal, the flow setpoint for the SAF and EAF will be controlled in normal speed.
The signal can be configured by using scaling: Min volt input (Vmin)/Min flow and Max volt input (Vmax)/
Max flow. The configuration is done in Configuration ► Analog inputs ► External control supply air fan and
External control extract air fan
Supply air pressure and extract air fan slave
The rotational speed of the supply air fan is controlled by a pressure transmitter which is placed in the supply air duct. The extract air fan does not have a pressure transmitter, instead you let the output for the extract air fan follow the control signal for the supply air fan. A scaling factor can be added if the characteristics of the extract air fan are not the same as the characteristics of the supply air fan.
The extract air fan will start directly at 50% after the start delay. Then the heating of the exchanger will work for this operating mode as well. When the supply air fan starts, the extract air fan will be slave controlled by the supply air flow.
Corrigo manual, Rev. D 77 (196)
Information for the specialist - Function descriptions
Supply air pressure with extract air flow slave
The rotational speed of the supply air fan is controlled by a pressure transmitter which is placed in the supply air duct. The extract air fan is controlled by the supply air flow, in order to achieve a balanced ventilation. A pressure transmitter which is placed in the supply air fan cone ( SAF flow ) gives a measured value of the present supply air flow. A corresponding pressure transmitter is placed in the extract air fan cone and gives a measured value of the extract air flow.
The supply air flow is the setpoint used for control of the extract air fan. A scaling factor can be added if the extract air fan does not have the same characteristics as the supply air fan. The scaling factor is found in
Ventilation ► Fan control ► Slave factor
Extract air pressure with supply air fan 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). The scaling factor is found in Ventilation ► Fan control ► Slave factor .
Extract air fan pressure with supply air flow 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 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 ( EAF flow ) provides a measurement of the current extract air flow. A corresponding pressure transmitter is placed in the supply air fan cone, providing a measurement of the supply air flow.
The supply air fan is controlled using the extract air flow as a setpoint. A scaling factor can be added if the supply air fan does not have the same characteristics as the extract air fan. The scaling factor is found in

Step controlled fans
It is possible to control the speed of the fans via digital outputs if the type of fan control is set to Manual or
External ( Configuration ► Functions ► Function activation ► Fan control type ).
Fans with up to 3 speeds can be controlled by this function ( Configuration ► Functions ► Fan control ► Step control of fans) . The function converts the control signal of the fan to start/stop signals for the step outputs.
Switch points and hysteresis are settable parameters ( Configuration ► Functions ► Fan control ► Switch point step 1-2 SAF / 2-3 SAF / 1-2 EAF / 2-3 EAF (%), Hysteresis (% )). The switch between the steps of the fans is delayed by a timer Speed change delay (s) (FS = 10s) ( Ventilation ► Fan control ► Supply air fan/Extract air fan ). When increasing the speed, the fan must run at the lower speed for the set delay time before the next higher speed is activated. If the speed is reduced, the output of the higher stage is switched off and the lower stage is switched on after the delay time has expired. Only the output of the selected speed is active.

Kitchen function
Kitchen function is an additional function for external controlled fans; Fan control type = External . The function will stop the unit if the external control signal is lower than a settable limit. A potentiometer which is connected to an analog input can start and stop the air handling unit in addition to control the speed of the fans.
The following settings need to be done to get the function activated:
✓ Fan control type = External ( Configuration ► Functions ► Function activation ► Fan control type )
✓ Kitchen function = Yes ( Configuration ► Functions ► Fan control ► Kitchen function )
✓ Analog input: External control supply air fan and External control extract fan ( Configuration ► Analog inputs ) configured to the same physical input
Different speeds of the fans can be achieved by differently adjusted curves for the two analog inputs. ( Configuration ► Analog inputs ► External control xxx fan ► Min/Max input (V), Min/Max signal(%) ).
The unit will stop if the voltage at the input External control supply air fan falls below the Min input (V). It starts again if the signal rises above the Min input (V) + a fix hysteresis of 0,1V.

Demand controlled ventilation
In applications with varying occupancy the fan speeds or mixing dampers can be controlled by the air quality as measured by a CO
2 sensor.
With the CO
2 function it’s possible to start and stop the fans, compensate the fan speed and in combination with mixing damper let in more outdoor air depending on the CO
2 value.
When the function is activated with start/stop function and the CO
2 value rises above a settable start value
(default: 800 ppm) the fans will start at configured speed (default: normal speed), if they are not already running. Should the CO
2 value continue to rise, the fan speed can increase if compensation with CO
2 value
Corrigo manual, Rev. D 79 (196)
Information for the specialist - Function descriptions
is configured (See function Fan compensation curve 1 in Application tool ). The fans will stop when the CO
2 value falls a settable hysteresis (default: 160 ppm) below the start value.
If demand controlled ventilation is activated in combination with mixing dampers and the CO
2
-value rises above the setpoint value, the dampers controlled by a sequence with CO
2 function will be overtaken by the
CO
2 controller and let in more outdoor air. The function is controlled by a PI-controller.
The function has a settable minimum running time.

Control of dampers and pump for preheated or pre-cooled outdoor air via an underground intake channel.
The digital output Pretreatment is set to preheating when the unit is started and the outdoor temperature is below the set heating start limit (default 8°C) or to precooling when the outdoor temperature is above the set cooling start limit (default 19°C).
If the outdoor temperature exceeds the set heating start limit by more than 1°C, preheating will be stopped, as well as if the outdoor temperature falls below the cooling start limit by 1°C.
If a sensor is configured in the intake duct this temperature will be compared with the outdoor temperature.
If the temperature in the intake duct does not exceed the outdoor temperature by more than 1°C
(adjustable) 5 minutes (adjustable) after start-up when using preheating, preheating will be stopped. The same conditions apply to precooling, i.e. if the intake temperature is not more than 1°C (adjustable) cooler than the outdoor temperature, precooling will be stopped.
Corrigo manual, Rev. D 85 (196)
Information for the specialist - Function descriptions
Pretreatment always starts at start-up of the unit, if the outdoor temperature so permits. If pretreatment is stopped due to a small difference between the intake temperature and the outdoor temperature, pretreatment will be blocked for 6 hours. Then pretreatment will start (if the outdoor temperature so permits) and run for at least 5 minutes (adjustable)

4.8 Humidity control
Humidity control can be configured as Humidification, Dehumidification or both Humidification and
Dehumidification.
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.
4.8.1
Humidification
An analog output is used to control a humidifier. The output will increase on decreasing humidity. A digital output can also be used to start a humidifier.
Maximum limitation function using duct humidity sensor:
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.
4.8.2
Dehumidification
An analogue output ( Humidity control ) is used to control a dehumidifier. The output will increase on increasing humidity. A digital output can also be used to start a dehumidifier.
86 (196) Corrigo manual, Rev. D
Information for the specialist - Function descriptions
4.8.3
Humidification / Dehumidification
An analogue output ( Humidity control ) is used to control a humidifier. The output will increase on decreasing humidity.
For dehumidification it’s configurable which sequence that should be activated for dehumidification through condensation. The parameter for configuration is at Configuration ► Functions ► Humidity control ► Select sequence for dehumidify . The output will increase on increasing humidity. This signal overrides the cooling signal from the temperature controller so the output can be activated for dehumidification even if the temperature controller demand is zero.
cooler is placed first in the air stream so that the exchanger and heater can be used to reheat the air after dehumidification.
4.8.4
Digital humidity signal
A digital output signal, Humidity control start , 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.
Setpoints are found in Ventilation ► Humidity control
If a start signal is needed for a cooling unit or a magnetic valve for DX dehumidification, the digital output signal for the configured sequence Sequence x pump should be used. In this case, the pump stop delay should be set to 0 s ( Ventilation ► Temperature control ► Sequence x ► Pump stop delay ).

4.9 Filter monitoring
Turn on filter monitoring in Configuration ► Functions ► Function activation .
Analog filter guards may be made air flow dependent. This means that a higher pressure drop is permitted across a filter at a higher air flow. For this purpose, X and Y coordinates are used to set the linear function that should be followed at a pressure drop alarm. They can also be accessed through the alarm settings in the display. FS = X1:0 m 3 /h, Y1:10 Pa : X2:2000 m 3 /h, Y2:150 Pa.
If a constant pressure drop alarm level is wanted, Y1 and Y2 should be set to the same value. In cases where flow control is not used, the first pressure value applies to pressure drop alarms (Y1).

Information for the specialist - Function descriptions
4.12 SFP, Specific Fan Power
When the frequency controlled fans are connected via Modbus and also supply information on motor output, the Corrigo is capable of calculating SFP using the following formula:
SFP = Total effect from all fans / Supply air fan flow (in m 3 /s)
If both SAF and EAF flow transmitters are connected the controller uses the highest value. If only the SAF flow is connected that is used. If no flow sensor is connected it uses the highest calculated flow from the SAF pressure transmitter or EAF pressure transmitter.
Power loss as a percentage of the frequency converter can be added for calculating the total output. If, for instance, power loss is 5 %, the total output will be as follows:
Total output = (Supply air fan output + Extract air fan output) x 1.05
A daily and a monthly average (always 30 days) are also computed and presented. SFP for the average values is calculated only when the unit is running
The SFP values are displayed in Ventilation ► Energy consumption ► SFP
4.13 Extra controller
An independent temperature control circuit for control of for example a separate zone. The circuit can be configured to heating or cooling. It has an analog input signal for temperature sensors and an analog output signal 0…10 V. There is also a digital output signal which is activated when the analog output signal is above
1 V and deactivated when the analog signal is below 0.1 V. The circuit can be configured to be active all the time or to be active only when the unit is running or when defrosting.
An alarm will be triggered if Extra controller is in manual position or if a sensor error occurs.
The extra controller can also be controlled by freeze protection.
Type of freeze protection: Freeze protection temp 1-3.

Description More information
The speed of the supply air fan is controlled by a pressure transmitter which is placed in the supply air duct. The extract air fan is controlled by the supply air flow, in order to achieve a balanced ventilation. A pressure transmitter which is placed in the supply air fan cone (SAF flow) gives a measured value of the present supply air flow. A corresponding pressure transmitter is placed in the extract air fan cone and gives a measured value of the extract air flow.
The supply air flow is the setpoint used for control of the extract air fan. A scaling factor can be added if the extract air fan does not have the same characteristics as the supply air fan.

Fan levels
A frequency controlled fan is the only type of fan that works with the Corrigo. The fan can be set to Low,
Normal or High speed. The selection of the fan speed defines which IOs and time channels will be active in the application.
The fans will always start directly with the desired speed.
There are four different fan speed levels to choose from in Application tool:
✓ Normal
✓ Low - Normal
✓ Normal - High
✓ Low - Normal- High
Variable speed control uses an analogue output per fan or Modbus communication for controlling a frequency converter.
For more information about frequency converters, see
Appendix F Frequency converters and EC controllers for heat exchangers
110 (196) Corrigo manual, Rev. D
Information for the specialist - Configuration
The fans are normally controlled by the timer channels for slow, normal and high speed but can also be started via digital input or communication.
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 will be created using an external time relay.
Fan compensation
When running pressure/flow control or manual frequency control, it is also possible to for the pressure/flow or output to be temperature compensated.
This compensation can be made depending on any analogue input such as supply air, extract air, room, outdoor temperature, humidity, CO
2 and so on. There are three equal compensation functions available.
It is possible to compensate either one or both of the fans at the same time and it is possible to set which fan should then be compensated, the supply fan or the extract air fan.
Read more about fan compensation in
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.
Support control can also be configured to start only with the supply air fan. In this mode, the extract air fan is not active. This requires a digital output to be configured, which controls the recirculation damper to open completely so the supply air fan can circulate the air to and from the room.

Free cooling
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.
Free cooling requires an outdoor sensor or an intake temperature sensor and either a room sensor or an extract air sensor. If both an outdoor sensor and an intake sensor is configured it uses the outdoor sensor for the function.
Free cooling is only activated when all the start conditions below are fulfilled.
✓ Less than four days have passed since the unit was last in running mode.
✓ The outdoor temperature during the previous running period exceeded a set limit (22°C).
✓ It is between 00:00 and 07:00:00 in the day (settable).
✓ The timer outputs for Normal speed, Extended running, Normal and External switch are Off .
✓ A timer channel will be On sometime during the next 24 hours.
If an intake sensor is used 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 (settable) to ensure that the temperature measurement when using an extract air sensor reflects the corresponding room temperature and that the intake temperature sensor senses the outdoor temperature even if it is placed in the fresh air inlet duct. If an outdoor sensor and a room sensor is selected, the unit will not start free cooling as long as all the temperatures are not within the start and stop temperature intervals.

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 Extra time channel 4 (
Application tool - Time control). If timer output for Low/Normal/High speed is activated during recirculation via Extra time channel 4 , Low/Normal/High speed gets priority. If timer output for Low/Normal/
High speed is activated during recirculation activated by a digital input, recirculation gets priority.
Either a digital output (Recirculation damper) or an analogue output sequence (A toJ) can be used as an on/ off output signal.
Recirculation control can be configured as either air circulation (temperature control inactive) or air circulation with temperature control. (Only heating, only cooling or both heating and cooling). Recirculation control has its own setpoint. However, the other settings are the same as for normal operation, i. e. if normal operation has been configured as room control, room control will also be used during recirculation.

Information for the specialist - Configuration
The digital output Pretreatment is set to preheating when the unit is started and the outdoor temperature is below the set heating start limit or to precooling when the outdoor temperature is above the set cooling start limit. If the outdoor temperature exceeds the set heating start limit by more than 1°C, preheating will be aborted, as well as if the outdoor temperature falls below the cooling start limit by 1°C.

Extra controller
An extra controller can be used as an independent temperature control circuit for control of for example separate zones. The circuit can be configured to heating or cooling. It has an analog input signal for temperature sensors and an analogue output signal (0…10 V). There is also a digital output signal which is activated when the analogue output signal is above 1 V and deactivated when the analogue signal is below
0.1 V. The circuit can be configured to be active all the time or to be active only when the unit is running or when defrosting.

Humidification + Dehumidification An analogue output ( Humidity ) is used to control a humidifier. The output will increase on decreasing humidity.
For dehumidification it’s configurable which sequence that should be activated for dehumidification through condensation. The output will increase on increasing humidity. This signal overrides the cooling signal from the temperature controller so the output can be activated for dehumidification even if the temperature controller demand is zero.

Filter monitoring
Turn on filter monitoring to monitor the flow through the filter. Analog filter guards may be made air flow dependent. This means that a higher pressure drop is permitted across a filter at a higher air flow.

Starting order heating/cooling
Setting of the order of the sequences is made in Configuration ► Functions ► Sequence heating/cooling.
It is possible to define a specific start order for the different sequences for heating and cooling demand.
The selectable number, 1…10, defines the start order of the sequences. If two sequences have the same start order they will work in parallel.
Start order heating shows only sequences which can work as a heating sequence, such as:
✓ Heater
✓ Exchanger
✓ Damper
✓ Fan setpoint compensation
Start order cooling shows only sequences which can work as a cooling sequence, such as:
✓ Cooler
✓ Exchanger
✓ Damper
✓ Fan setpoint compensation
The following picture (
5-9 ) shows the default settings of the configured sequences A=Heater, B=Exchanger
and C=Cooler, where the Exchanger (SEQ. B) starts first in heating mode followed by the Heater (SEQ. A).
In cooling mode, the Exchanger (SEQ. B) starts first followed by the Cooler (SEQ. C).

Sequence settings
These settings are used the define the start of the sequences when the unit starts. There are two different modes to start the unit:
✓ Normal start up
✓ Warm (Heat) start up
Normal start up:
The sequence control starts at 100% for the heating sequence which is selected at the parameter At start up begin temperature control at 100% in . The default setting is Heating 1 , which means it starts at 100% for heating sequence 1 which is the exchanger in the default configuration.
Corrigo manual, Rev. D 119 (196)
Information for the specialist - Configuration
Warm start up:
If the outdoor temperature is lower than the settable limit Warm start up if outdoor temperature < (°C) the unit will start in the warm start mode. A second sequence will start at 100% in this mode if the unit starts. The default setting is Heating 2 , which means it starts at 100% for the heating sequence 2 which is the heater in the default configuration

Support control
Set if the extract fan will be running or not during 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.
Support control can also be configured to start only with the supply air fan. In this mode, the extract air fan is not active. This requires a digital output to be configured, which controls the recirculation damper to open completely so the supply air fan can circulate the air to and from the room.

5.12.2 Alarm configuration
The alarm configuration menu permits configuration of the priority for all alarms. A complete alarm list with default settings and actions, can be found in
Appendix D Alarm list . It contains all the default alarm texts and
priorities.
Priority
Alarms can be given different priority levels A-alarm , B-alarm and 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.
The alarm priority that is shown in the display in the event of an alarm can only be changed using
Application tool.
Alarm text
The alarm text that is shown in the display in the event of an alarm can be changed using Application tool or the web interface.
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 Application 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. Therefore, for such alarm types, the program will always reset the stop function to Active even if the operator should choose Inactive .
Corrigo manual, Rev. D 153 (196)
