10. Operating level 2
Quick heating
Prerequisite:
− Extract air temperature sensor or room temperature sensor installed
− Damper system for quick heat-up installed
The quick heat-up function can be enabled in the "standard settings".
During system start-up and in control mode, the ACTUAL room/extract air
temperature and the SET room/extract air temperature are continuously
compared. If the actual temperature is below the set temperature by
an adjustable value (e.g. 5 K), the quick heat-up function is enabled.
This means recirculating air operation with the set maximum supply air
temperature.
Once the ACTUAL room/extract air temperature has reached the SET room/
extract air temperature (incl. adjustable offset), the unit changes back into
control mode.
If the SET room/extract air temperature (incl. offset) is not achieved, the
unit switches back into control mode after an adjustable max. runtime (e.g.
60 min).
If the quick heat-up function is enabled, this is shown on the default screen
as a special operating mode.
