Sensitivity of the central humidity sensor (accessories):
The sensitivity of the humidity control (response char-
acteristics) can be adjusted if a humidity sensor is
installed in the central extract air duct (header)
("Humidity sensor C105" is set to "1").
For this a setting range of "–2" (less sensitive) to "+2"
(more sensitive) is available.

When outside temperatures are low, the outdoor air
can be preheated by a geothermal heat exchanger (on
site), e.g. to protect the heat exchanger against frost.
Below the set temperature, the 3-way diverter damper
opens up the path through the geothermal heat
exchanger. Above the set temperature the outdoor air
flows directly into the ventilation unit.
Setting 1 ≙ 0.1 °C

When outside temperatures are warm, the outdoor air
can be routed through a geothermal heat exchanger
(on site), e.g. for central cooling. Above the set tem-
perature, the 3-way diverter damper opens up the path
through the geothermal heat exchanger. Below the set
temperature the outdoor air flows directly into the ven-
tilation unit uncooled.
