=
interval mode
. The defrost starts when the time “
Idf
” is expired.

(defrost end based on temperature) it sets
the maximum length for defrost.
dSd Start defrost delay

sets the evaporator fan ON cycling time when the compressor is off. With Fon =0 and FoF
≠
0
the fan are always off, with Fon=0 and FoF =0 the fan are always off.
FoF Fan OFF time:
