Main function
The control is a weather compensator with an outdoor tem-
perature sensor that is fitted in the open air.
The control is connected to the outdoor temperature sensor
and the heat generator. The control controls the heating
installation and other connected components, e.g. the do-
mestic hot water generation for a connected domestic hot
water cylinder or the ventilation of a connected ventilation
unit.
3.2.1
Heating
The outdoor temperature sensor measures the outdoor tem-
perature and forwards the values to the control. When the
outside temperature is low, the controller increases the flow
temperature of the heating installation. If the outdoor temper-
ature increases, the control reduces the flow temperature.
The control responds to the fluctuations in the outdoor tem-
perature and uses the flow temperature to ensure that the
room temperature remains at the required temperature.
3.2.2
Cooling
The room temperature sensor measures the room temperat-
ure and sends the data to the controller. If the room temper-
ature is higher than the desired temperature that is set, the
controller switches cooling on.
3.2.3
Ventilation
Using a controlled exchange of air, the ventilation unit en-
sures that the living rooms are ventilated and aerated. The
control controls the air volume flow via the ventilation levels
that are set.
