CORRIGO VENTILATION 3.6 MANU

Manual Corrigo Ventilation, revision V Chapter 5 Functional description 53
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 E 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".
Unfortunately it is not possible to remove the display text concerning the stop function for these alarm
types. This since the available program space demands that all alarms are treated in the same way in
the display.
Note: For alarms that have been set to "Inactive", the extra stop function should also be set to
"Inactive", or unexpected malfunctions may occur.
Alarm text
The alarm text that should be shown in the display when there is an alarm can be changed using E

External alarms
There are 11 possible external alarms. One digital input called ”External Alarm” and 10 digital inputs
called ”Extra alarm”.
Fire function
Fire dampers are normally closed and configured to open if a fire takes place. However, it is possible
to instead configure them to be normally open, as well as to configure the controller operating mode
at a fire alarm. The following options are available: “Stopped", “Continuous run", “Run via normal
start/stop conditions”, “Only extract air fan in operation” or “Only supply air fan, 100 % heating and
alarm block”. “Alarm block” here means that all alarms will be blocked.
It is possible to configure which speed the fans should have when in fire mode – however, this is not
possible when the fire function has been set to “Run via normal start/stop conditions”. Setting the fan
speed to -1 % will deactivate the fan speed selection.
Fire alarm priority is for the unit to not stop for any other alarm (e.g. frost protection) when it has
been configured for continued operation during fire alarms. However, the digital input ”external
switch” will still stop the unit. See chapter 17.15 for more information.
