PARAMETER LIST
REGULATION
Hy
Differential: (0,1÷25,5°C; 1÷45°F): Intervention differential for set point, always positive. Compressor
Cut IN is Set Point Plus Differential (Hy). Compressor Cut OUT is when the temperature reaches the set
point.
LS
Minimum set point limit: (-50,0°C
point.
US
Maximum set point limit: (SET
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.
DISPLAY
CF
Temperature measurement unit: °C = Celsius; °F = Fahrenheit . When the measurement unit is
changed the SET point and the values of the regulation parameters have to be modified
rES Resolution (for °C): (in = 1°C; de = 0,1°C) allows decimal point display.
de = 0,1°C; in = 1 °C
Lod Local display : select which probe is displayed by the instrument:
P1 = Thermostat probe; P2 = Evaporator probe; P3 = auxiliary probe
1r2 = difference between P1 and P2 (P1-P2)
Red Remote display : select which probe is displayed by the remote display (XW-REP)
P1 = Thermostat probe; P2 = Evaporator probe; P3 = auxiliary probe
1r2 = difference between P1 and P2 (P1-P2)
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 = Smartfrost 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.
