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.
The controllers are available with or without a front panel display and buttons. For all third
generation units, both with and without display, a separate, cable-connected terminal E3-DSP with
display and buttons is available.
All configuration and normal handling can be done using the display and buttons or using the
configuration tool E tool©, installed on a PC and connected via the communication cable E-cable.
2.1 News in version 3.3
•The operating system has been further improved and is now called EXOrealC.
•Support for three communication ports.
•BACnet/IP is now available as a communication protocol.
•New filter alarm: Separate filter alarms.
•Analogue filter alarm, filter pressure alarm.
•Temperature alarm for extra sensors 1-5.
•Support for 0…10V outdoor sensor and room sensor.
•Modulating recirculation air damper, Y4-Extra sequence.
•Communication with Danfoss model Frequency converters FC 101 now supported.
•Additional Modbus signals.
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 and suitable languages 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 pre-
programmed 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. The maximum
number of I/Os is 3*28 (a 2- or 3-port Corrigo with two expansion units).
The Corrigo is designed for DIN-rail mounting.
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.
•Extra, separate temperature control circuit for after-heaters, etc.
•Extra control sequences Y4 and Y5 (in addition to Y1, Y2 and Y3) for free integration
into the controller output.
With control of:
•Heat exchanger (liquid connected, plate or rotating) or mixing dampers.
•Heating coil: Water with or without frost protection or electric with high temperature limit
switch.
•Cooling: Water or DX cooling in up to 3 steps.
•Circulation pumps heating, cooling, exchanger.
Fan control
•1- or 2-speed supply air and extract air fans.
•Frequency controlled supply and extract air fans with pressure or flow control, manual
control or external control from a VAV system.
•Pressure controlled supply air fan with slave connected extract air fan (output dependent or
flow dependent) or opposite function (pressure controlled extract air fan with slave
connected supply air fan, output dependent or flow dependent).
Humidity control
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 5 timer outputs for control of
external functions such as lighting, doorlocks etc.

10 Chapter 2 About Corrigo Manual Corrigo Ventilation, revision R
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 CO2sensor.
Support control
When using the control function room control or extract air temperature control, it is possible to
utilise support-heating and/or support-cooling.
Free cooling
When this function has been activated, it is used during the summer to cool the building during the
night 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
As an alternative to the analogue control of ”Actuator heating Y1” or ”Actuator cooling Y3” step
controllers can be used for controlling heating or cooling in steps using digital control.
Change-over
In 2-pipe systems where a combination heater/cooler is operating together with a heat pump,
Change-over is a function that enables using the same pipe for both heating and cooling, depending
on which is currently required. It uses the output Y1 Heating/Y3 Cooling.

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
At the end of this chapter there are wiring diagrams showing the factory set configuration. There are
also empty wiring diagrams. Since the function of most of the inputs and outputs depends on the
programming of the unit the final wiring diagram cannot be filled in until the installer has decided
how to use the inputs/outputs. It is important to ensure that the wiring is performed correctly and in
accordance with the instructions given in this manual.

Manual Corrigo Ventilation, revision R Chapter 3 Installation and wiring 15
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.
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.
Digital inputs
Digital inputs must refer to +C on terminal 4. Digital inputs may only be wired to voltage-free
contacts. Any external voltage applied to a digital input may harm the unit. The input signal can be
set to either NO or NC.
Universal inputs
A universal input can be configured to act as either an analogue input or as a digital input.
A universal input configured as an analogue input 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.
Universal inputs configured as an analogue input must refer to an Agnd terminal placed in the same
terminal block as the input being wired.
A universal input configured as a digital input must, just like other digital inputs refer to C+ on
terminal 4. It may only be wired to voltage-free contacts.
Analogue outputs
Analogue outputs must refer to the Agnd terminal placed in the AO terminal block.
All analogue outputs can be individually set to any one of the following signals:
0…10 V DC
2…10 V DC
10…0 V DC
10…2 V DC
If the Corrigo and the actuators connected to it share the same transformer it is essential that the
same transformer-pole is used as reference for all the equipment. Failure to do so will prevent the
equipment from functioning as intended and may also lead to damages.
Digital outputs
Digital outputs should normally refer to GDO on terminal 10. GDO is internally connected to G on
terminal 1 and supplies 24 V AC or DC depending on the choice of supply voltage.
All the digital outputs are controlled by MOSFET transistors. The outputs are internally connected
with G0and can deliver max 2 A per output. However, the total power for all the DOs must not be
over 8 A.
