OdS Outputs activation delay at start up: (0÷255 min) This function is enabled at the initial start up of the
instrument and inhibits any output activation for the period of time set in the parameter. (AUX and Light
can work)
AC Anti-short cycle delay: (0÷30 min) interval between the compressor stop and the following restart.
CCt Thermostat override: (0min ÷23h 50min) allows to set the length of the continuous cycle. Can be used,
for instance, when the room is filled with new products.
Con Compressor ON time with faulty probe: (0÷255 min) time during which the compressor is active in case
of faulty thermostat probe. With COn=0 compressor is always OFF.
COF Compressor OFF time with faulty probe: (0÷255 min) time during which the compressor is off in case of
faulty thermostat probe. With COF=0 compressor is always active.

DEFROST
tdF Defrost type:
rE = electrical heater (Compressor OFF)
rT = thermostat defrost. During the defrost time "MdF", the heater switches On and OFF depending on the
evaporator temperature and "dtE" value.
in = hot gas (Compressor and defrost relays ON)
EdF Defrost mode:
rtc = Real Time Clock mode. Defrost time follows Ld1÷Ld8 parameters on workdays and Sd1÷Sd8 on
holidays.
in = interval mode. The defrost starts when the time "Idf" is expired.
Sd = Smart Defrost mode. The time IdF (interval between defrosts) is increased only when the
compressor is running (even non consecutively) and only if the evaporator temperature is less than the
value in "SdF" (set point for SMARTFROST).
SdF Set point for SMARTFROST: (-30
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 (Maximum) 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.

it = temperature reading at the defrost start;
