Manual Corrigo E Ventilation, revision Q About Corrigo E 7
Chapter 2 About Corrigo E
Corrigo E series comprises three model sizes: 8, 15 or 28 in-/outputs.
In each model of Corrigo E generation 2, all applications are loaded in a separate memory area. The
models have article number E...-S (where S stands for Second generation). From version 3.0, there
are models with two communication ports. By connecting one/two expansion units to port two on
these units, it is possible to increase the number of inputs and outputs. The 2-port Corrigo models
have article number E...2-S (where the number two stands for 2 ports). For more detailed
information, see chapter 17.
The controllers are available with or without front panel display and buttons. For units without front
panel display and buttons a separate, cable-connected terminal E-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.

2.2 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. 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-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 control.
Outdoor compensated supply air control.
Room temperature control (cascade control).
Extract air control (cascade control).
Outdoor temperature dependent supply air or room temperature control.
Outdoor temperature dependent supply air or extract air control.
Outdoor compensated room temperature control.
Outdoor compensated extract air control.
With control of:
Heat exchanger (Liquid connected- , plate- or rotating) or mixing dampers.
Heating coil; Water with frost protection or electric.
Chiller: Water-heated or DX in up to three steps.
Circulation pumps heating, cooling, exchanger.
Fan control
1- or 2-speed supply air fans 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). Pressure controlled extract air fan with slave
connected supply air fan (output dependent or flow dependent).
Humidity control
Either humidification or dehumidification, or both humidification and dehumidification.
Timer control
For starting and stopping the unit. Up to five timer outputs for control of external functions such as
lighting, doorlocks etc.
Demand control
In buildings with strongly varying occupancy the fan speeds or mixing dampers can be controlled
by the air quality measured by a CO2/VOC sensor.

10 About Corrigo E Manual Corrigo E Ventilation, revision Q
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. Minimum running time is settable 0…720 minutes
(factory setting 20 minutes).
Free cooling
The function 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. The function can also be activated during
daytime if the temperature so allows.
Enthalpy control for free cooling/heating
This function is used to override the mixing damper to increasing recirculation depending on the
result of the enthalpy calculation.
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. This function also activates the heating function
“Free heating” (see section titled “Free heating” below).
Free heating
If the extract air is cooler than the outdoor air and heating is required, outdoor air will primarily be
used.
Recirculation control
Recirculation of air using a supply air fan and recirculation damper, with or without temperature
control.
Pretreatment
Preheating or precooling of the intake air via an underground intake channel.
Step controllers Heating/Cooling
As an alternative to the analogue control of ”Actuator heating Y1” or ”Actuator cooling Y3”, step
controllers can be used to control heating or cooling in steps using digital control.

Chapter 3 Installation and wiring
3.1 Installation
Corrigo E 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 E28.
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.
3.2.1 Supply voltage
24 V AC ±15%, 50…60 Hz or 21…36 V DC
If Corrigo E 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.

Manual Corrigo E Ventilation, revision Q Installation and wiring 15
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 E 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.
A number of different wiring alternatives are possible depending on the type of supply voltage to
the Corrigo and the relay type.
