- Triac impulse duration
F12: This represents the duration in milliseconds for the impulse applied to the triac. For induction mo-
tors, set the parameter to 2 (default). On the other hand, when using the CONVONOFF0, CONV0/10A0
modules or FCS controllers, set the parameter to 0.
- Fan management mode in defrost
F13:
This parameter sets the operating logic for the condensing fans during the defrost phase:
F13 = 0: (default) the fans are OFF.
F13 = 1: the fans are ON as in cooling mode, based on the temperature or pressure.
F13 = 2: the fans are OFF until the end defrost temperature or pressure is reached, above which they are
started at maximum speed for the time set for parameter d16. Only at the end of this time will the cycle
return to heat pump mode with the normal management of the fans.
Note: If the unit is running the Fan Defrost function (parameter d17), the fan management selected by
F13 is disabled.
