works in the reverse manner: It reduces the speed of the
supply air fan and lets the extract air fan continue operating
at the same speed�

ence detector is installed, otherwise select OFF�
3.6.11 Electric air heater (optional equipment)
Select ON as the value for Electric air heater, otherwise select
Off� Select 10 °C as the value for Outdoor air temp� This
means that the air heater will not be activated, when the
outdoor air temperature exceeds 10 °C °C� The temperature
limit can be changed�
The temperature sensor, T2, for sup-
ply air temporary decreases the fan speed
if the supply air becomes too cold. If the
supply air temperature drops below +11 °C,
the controller stops the supply air fan (this
protects against moisture condensing on
the exterior surfaces of the supply air duct).
