DEFROST
tdF Defrost type: rE = electrical heater (Compressor OFF)
in = hot gas (Compressor and defrost relays ON)
EdF Defrost mode: in = interval mode. The defrost starts when the time "Idf" is expired.

compressor is running (even non consecutively).
SdF Set point for SMARTFROST: (-30
IdF counting (interval between defrosts) in SMARTFROST mode.
dtE Defrost termination temperature: (-50,0÷110,0°C; -58÷230°F) (Enabled only when the
evaporator probe is present) sets the temperature measured by the evaporator probe which
causes the end of defrost.
IdF Interval between defrosts: (1÷120h) Determines the time interval between the beginning of two
defrost cycles.
MdF Duration of defrost: (0÷255 min) When P2P = n, no evaporator probe, it sets the defrost
duration, when P2P = y, defrost end based on temperature, it sets the maximum length for
defrost.

rt = real temperature; it = temperature reading at the defrost start;
Set = set point; dEF = "dEF" label;
dAd Defrost display time out: (0

water drops that might have formed due to defrost.
