Fd: post dripping off (active both when F0=0 and F0=1)
The fans, after the defrost, can be stopped for a further period (in minutes) defined by the value of Fd. This is useful to allow the
evaporator to return to operating temperature after the defrost, thus avoiding forcing 'hot' air into the refrigerator. In the case of
management by fan controller, the time Fd does not need to be selected, in that the controller makes the fans start again when the
evaporator reaches operating temperature. If the fan controller is active (F0=1), assigning Fd a value other than zero means the
fans stay off for a time equal to the value of Fd, irrespective of the temperature of the evaporator.
Def.: Fd= 1 minute post-dripping stop. Available on: PJ32C.
