In case of malfunction with the code on grey background, the unit still operates. However, make sure to have it inspected and repaired as soon as possible.
Prevent of frost the heat-exchanger
•
If electrical pre-heating is present:
-
electrical pre-heating coil will prevent frosting of the heat-exchanger, modulating once the fresh air temperature goes below the threshold value set at 0°C, in case of heater
malfunction or not sufficient flow for its startup, a differential pressure switch will shutdown the unit until the defrosting.
•
If electrical pre-heating coil is not present:
-
a differential pressure switch will prevent frosting of heat exchanger, shutting down the unit once the frosting starts.
