6.2 Automatic mode
The automatic mode controls the air performance of supply and extract air based on the humidity and/or VOC sensor which can
be installed in the extract air connector of the ventilation unit.
Switching of the ventilation modes with the installed central VOC sensor:
< 1,000 ppm = mode 1
1,000–1,500 ppm = mode 2
1,500–2,000 ppm = mode 3
> 2,000 ppm = mode 4
Switching of the ventilation modes with the installed central humidity sensor:
n
If the humidity exceeds the set target value, the ventilation unit will continuously operate in ventilation mode 3.
n
If the humidity drops below the set target value, the ventilation unit will adjust the airflow rates by gradual reduction.
n
If the humidity remains below the set target value over a longer period of time, the ventilation unit will switch to ventilation
mode 1.
Using the profi-air cockpit pro software or the wireless remote control, you can adjust the factory-set
humidity of 45 % r.H.
6.3 Automatic summer bypass
With the automatic summer bypass, heat
recovery is prevented in order not to addi-
tionally heat the cooler fresh air with the
extract air. This function is mainly used in
transitional seasons as well as during cool
summer nights. The bypass operates fully
automatically according to the set control
temperature.
Control temperatures
n
The fresh air temperature is the release temperature – only after the set
temperature has been exceeded, the control releases the summer bypass
open function.
n
The extract air temperature is the control temperature – only after the set
temperature has been exceeded and the fresh air temperature is lower
than the extract air temperature, the bypass opens.
Using the profi-air cockpit pro software allows you to adjust the sensitivity of the VOC sensor.
