FAN Evaporator fans
The fans can be turned off in the following situations:
l when the solenoid valve is deactivated (parameter F2);
l during defrosts (parameter F3).
During the dripping time (parameter dd > 0) the fans are off, and during the post- dripping time
(parameter Fd > 0), the evaporator fans are on or off depending on the value of parameter Fpd.
This is useful to allow the evaporator to return to temperature after defrosting, thus avoiding blowing
warm hot and moist air into the refrigerated environment.
The evaporator fans can be forced on during control (parameter F2) and during defrosts (parameter F3).
