6.6.3.1 Cyclical defrosting with minimum temperatures

The set point must be determined along with its differential for the activation of the defrosting

cycle.

When the anti-freeze minimum temperature condition is reached a cyclical by-pass sequence of the

recovery heat exchanger is activated to allow the exhaust air (warmer, from the room) to defrost the

recovery heat exchanger air channels as shown in the below diagram.

After the (parameter Pr03) delay the by-pass damper is activated to allow defrosting. As soon as the

exhaust air temperature is back above the accepted value the damper is deactivated and the recovery

heat exchanger starts again.

Note: If the anti-freeze probe is in alarm condition the function is disabled.
