About Corrigo E
Corrigo E is a series of pre-programmed, configurable controllers for different applications.
The Corrigo E series comprises three model sizes: 8, 15 or 28 in-/outputs.
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 normal handling can be done using the display and buttons or from a connected computer
running Corrigo E tool and using EXOline for communication.
Ventilation application, overview of functions
The controller is loaded with programs for controlling a ventilation unit. The temperature
controller is based on a supply air PI-controller for heating control with a pre-programmed
set of control modes. To this controller can be bound a number of different control functions
and analogue and digital input and output functions. Certain functions are necessary, others
can be seen as functional options. This flexibility means that what is shown in the display
may differ from one unit to another, depending on which functions have been selected.
Functional choices are not made in the operator level, but in the Service or System levels by
educated personnel with specialised knowledge. The same applies to other 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 controller)
Exhaust air temperature control (cascade controller).
Seasonal switching between supply air temperature control and room/extract air temperature
control.
Extra, separate temperature control circuit for after-heaters etc.
Corrigo E Ventilation User Guide, revision A

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, up to 3 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).
Humidity control
Either humidification or dehumidification or both humidification and dehumidification can
be used.
Timer control
For starting and stopping the unit. Up to 5 timer outputs for control of external functions
such as lighting, doorlocks 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 CO2/VOC 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.
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.
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 recirculation damper, with or without
temperature control.
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.

Sp: 18.0 Act: 18.2°C
The start display, the display normally shown, is at the
basic level of the menu tree. The appearance of the
start display may vary since there are 5 types to choose
from during configuration. The text in the first row can
also be changed via E tool.
Sp and Av are Setpoint and Actual value for the supply air controller. This also applies when
using cascade connected room temperature or extract air temperature control.
Actual value = The current measured temperature.
Setpoint value = The desired configured temperature.
Pressing ARROW DOWN will move you through the menu choices at this, the lowest level.
ARROW UP will move you back through the choices.
Which menus are shown depends on which access level you are using (see the section
Access rights for more information about logging on to higher levels).
The basic access level, the level normally active when you have not logged on, only shows a
limited number of menus and submenus:
Running mode
Here, you can view and set the unit’s running mode, as well as view selected control
functions and alarm events.
Temperature, Air control and Humidity control
Here, relevant values and setpoint values are displayed. Setpoints can only be changed if you
have Operator access or higher.
Time settings
Here, the time, date and set running times are shown. Values can only be changed if you
have Operator access or higher.

Use the eight breakpoints to generate a setpoint /
outdoor temperature relationship.
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.
For example: At the lower end the setpoint is increasing by 1°C for every 5 °C lowering of
the outdoor temperature. So the setpoint at –23°C would be 25°C + .6x 1.0°C = 25.6°C.

exhaust air sensor and an outdoor sensor.
When the control signal is lower than 98% or the outdoor temperature is higher than 10°C
the display will show 0%.
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 and a recirculation damper opens which allows
the air to circulate through the unit.

and the alarm class (A, B or C alarm).

If there are multiple alarms, this is indicated by up /
down arrow symbols at the right-hand edge of the
display.
Use the UP and DOWN buttons to access the other
alarms.
At the left end of the bottom display line the alarm status is shown. For active,
unacknowledged alarms the space is blank. For alarms that have reset the text: “Reset” is
shown, Acknowledged, still active or blocked alarms are indicated by Acknowledged or
Blocked.
Alarms are acknowledged by pressing the OK button. You are then given the choice of
acknowledging the alarm or blocking the alarm.
Acknowledged alarms will remain on the alarm list until the alarm input signal resets.
Blocked alarms remain on the alarm list until the alarm has reset and the block has been
removed. New alarms of the same type will not be activated as long as the block remains.
Since blocking alarms can be potentially hazardous, you need a high log on authority to
block alarms.
Class A and B alarms will activate alarm output(s) if these have been configured.
Class C alarms do not activate the alarm output(s).
Class C alarms are removed from the alarm list when the alarm input resets even if the alarm
has not been acknowledged.
Free text

is displayed. The text can be used to show information concerning the commissioning
company, name and phone number to service personnel etc. The easiest way to enter text is
to use E tool, but the buttons can also be used. Up to 4 lines of 20 characters can be entered.
Revision numbers
If RIGHT is pressed twice when the start-menu is shown, a menu showing the program
revision number and ID number is displayed.

Language
If RIGHT is pressed three times when the start-menu is shown, a menu is displayed in which
the language can be changed.
The different language files are stored in the application memory and are downloaded to the
work memory. If a Corrigo via E tool has been reloaded with a newer program revision than
the factory revision, the controller will not allow language files to be downloaded from the
application memory. This is because there is a risk that the language files are not compatible
with the new revision. Therefore, you are limited to the two languages you have downloaded
using E tool.
Indication LEDs
Status indication can be found in the upper left corner of the controller. For controllers with
display, the alarm indication and change mode LEDs are located in the keypad area.

Changing the battery
Corrigo has an internal battery to ensure the operation of the memory and real-time clock in
the event of a power failure.
When the alarm ”Internal Battery” is activated and the battery LED lights up red, the battery
has become too weak and needs to be changed. Nonetheless, due to a backup capacitor, the
controller will function at least 10 minutes without power supply.
Since changing the battery requires knowledge of proper ESD protection, as well as
dismantling and opening of the unit, this should be handled by skilled service personnel.
