2.5 Setting the CLOCK 2.5 Setting the CLOCK
See CLOCK for instruction on how to set
the correct time on the device. The device
uses the set time to execute the ventilation
program when in auto operation.
The following days can be chosen:
■ MON = Monday;
■ TUE = Tuesday;
■ WED = Wednesday;
■ THU = Thursday;
■ FRI = Friday;
■ SAT = Saturday;
■ SUN = Sunday.
CLOCK Back-up
The device can keep the clock running for at
least one hour without power. After that the
clock has to be set again. Before the back-
up is able to function fully, the device has to
be powered for at least 20 minutes. The set
values in the parameter menu's will always
be saved.
2.6 Setting the COMF
(Comfort temperature)
The ventilation unit strives for a comfortable
air temperature supply as possible on the
basis of a set comfort temperature.
It is best to set the comfort
temperature to the same
temperature as the room
thermostat (of the central heating
system).
See COMF for instruction on how to set
the comfort temperature.

unit is fi tted with an open fi re program.
When required the installer or maintenance
mechanic can turn this program on. If the fi re

manually.
When can de supply (IN) fan not be
turned on?
The supply (IN) fan can not only be operated

ventilation unit from freezing. If the supply
(IN) air is too cold for the ventilation unit, the
ventilation unit will switch the supply (IN) fan
automatically off. In this case the supply (IN)
fan cannot be turned on manually.
See FAN for instruction on how to switch
the fans on and off.
The following fan options can be chosen:
■ IN OFF
