6. Commissioning
Each unit is preprogrammed with a set of default
parameters. These preprogrammed settings are
stored on the main PCB and can always be restored
using parameter M99-99. Next to changing the
preprogrammed parameters on the display it is also
possible to load a new set of parameters to the
main PCB. This can be done with the special control
software “ComfoAir XL Control Center” or with
parameter M90-03.
More information about the “ComfoAir XL Control
Center” can be found in its own manual. More
information about parameter M90-03 can be found
in the chapter about using de SD card on the main
PCB.
Not all parameters can be set as default. Some
parameter settings depend on the hardware which
is installed on site. These parameters must be set
to the correct value after installing. How to set the
correct value can be found in this commissioning
chapter.
After fitting and commissioning, a number of checks
must be carried out. At the back of this document
is an installation report stating the points requiring
checking.
6.1 Air volume control (M02, M12-04)
The unit is preset with a set of air volumes for each
ventilation level. These preset air volumes can be
changed in parameter M02-01 till M02-08.
Function Parameter
Air volume Supply air 1 M02-01
Air volume Supply air 2 M02-02
Air volume Supply air 3 M02-03
Air volume Supply air 4 M02-04
Air volume Exhaust air 1 M02-05
Air volume Exhaust air 2 M02-06
Air volume Exhaust air 3 M02-07
Air volume Exhaust air 4 M02-08
The unit is preset with a maximum air volume
in parameter M04. These setting depend on
the type of fans installed. Do not change these
settings.
When two ventilation speeds are activated at the
same time the unit will run on the highest activated
ventilation speed. Regardless of the set volume of
that ventilation speed.
In order to achieve a smooth control, it is
recommended to program the ventilation levels in
linear progression. If the ventilation levels are not
programmed linearly, the fans might appear to be
running uncontrolled or even power down when
powering up was expected.
Positive sensor control
With a positive sensor control, power will go up if the
measurement is below the set point. In the event of
a higher measurement, power will go down. Most of
the pressure sensors use positive control.
0–10 V signal
Speed
Negative sensor control
With a negative sensor control, power will go up if
the measurement is higher than the set point. In the
event of a lower measurement, power will go down.
Most of the CO2 sensors use negative control.
0-10 V signal
Speed
Balanced ventilation (M12-04)
When desired the unit can maintain balanced
ventilation under all circumstances. Even when the
software requires the reduction of only one fan. If
the “balanced ventilation (frost)” option is activated
in parameter M12-04 (option 1) all fans will always
reduce or stop at the same time/rate.
The ComfoAir XL A is preset to balanced
ventilation.
