5.2 Supply air temperature control
The supply air temperature is regulated by changing the
temperature efficiency, with an integrated air heater or
with an air cooler, which is sold as an accessory.
In Eco mode the ventilation unit works with the best
possible temperature efficiency. It must be noted here
that the higher the extract air temperature, the greater
the direct effect will be on the supply air temperature.
The supply air temperature can be adjusted if necessary
by warmer supply air.
In Comfort mode the supply air temperature is kept
even with the help of partially passing heat recovery, i.e.
by controlling the temperature efficiency. It must be not-
ed here that the unit is not able to produce supply air
that is cooler than the outdoor air.
The control mode for the supply air is selected from the
temperature control settings. The default mode is Eco.
The temperature setpoint can be adjusted using the
control panel, weekly program, operating mode selec-
tion or based on room temperature.
Automatic summer night cooling recognizes the
need for cooling. The function lowers the supply air
temperature setting and bypasses the heat exchanger
for best cooling performance. The unit can't produce
cooler supply air than the outside air.
The unit can be equipped with an optional cooling coil,
which allows active cooling of the supply air.
5.2.1 Temperature control settings
The user can change the temperature setting from
the main menu. The preset value of the temperature
setting refers to the supply air temperature that the unit
attempts to reach. If room temperature regulation is
selected, the setting value determines the setpoint value
for the room temperature.
Supply temperature control settings can be accessed
from the Settings/(1234)/Heating / Cooling/Supply tem-
perature control menu.

If control method Room air is selected min and max val-
ues for heating and cooling (if external cooling device*
is installed) periods can be set. The room temperature
control method aims to control room temperature by
controlling supply air temperature between min and
max values.
The Room temperature setpoint and lowered setpoints
for Away and Travelling modes can be set. The heat
exchanger Control mode can be selected.
NOTE! The Automatic summer night cooling can lower
supply air temperature setpoint.
5.2.2 Temperature measurement
The supply and room temperature measurements can be
fine tuned from settings menu (Settings/(1234)/Heating /
Cooling/Sensors / Controls).
If SET module is attached supply, room, outside or water
radiator temperature sensor inputs can be selected.
