PARAMETERS
REGULATION
HY
Differential in standard mode: (0.1 to 25°C; 1 to 45°F) differential for set point used in normal
mode. Compressor Cut IN is SET+HY. Compressor Cut OUT is when the temperature reaches
the set point SET.
HE
Differential in energy saving mode: (0.1 to 25°C; 1 to 45°F) differential for set point used in
energy saving mode. Compressor Cut IN is SET_ES+HE. Compressor Cut OUT is when the
temperature reaches the set point SET_ES.
LS

US
Maximum SET POINT: (SET to 99°C; SET to 99°F) set the maximum value for set point.
ot
First probe calibration: (-9.9 to 9.9°C; -17 to 17°F) allows to adjust possible offset of the first
probe.
P2
Evaporator probe presence: (n; Y) n=not present; Y=probe configured as present.
oE
Second probe calibration: (-9.9 to 9.9°C; -17 to 17°F) allows to adjust possible offset of the
second probe.
P3
Third probe presence: (n; Y) n=not present; Y=probe configured as present.
F3
Third probe calibration: (-9.9 to 9.9°C; -17 to 17°F) allows to adjust possible offset of the
second probe.
od
Outputs activation delay at start up: (0 to 99 min) this function is enabled at the initial start-
up of the instrument and inhibits any output activation for the period set in the parameter.
AC
Anti-short cycle delay: (0 to 99 min) minimum interval between the compressor stop and the
following restart.
CY
Compressor ON time with faulty probe: (0 to 99min) time during which the compressor is
active in case of faulty thermostat probe. With CY=0 compressor is always OFF.
Cn
Compressor OFF time with faulty probe: (0 to 99min) time during which the compressor is
OFF in case of faulty thermostat probe. With Cn=0 compressor is always active.
DISPLAY
CF
Measurement unit: (°C; °F) °C=Celsius; °F=Fahrenheit. WARNING: When the
measurement unit is changed the SET point and the values of the parameters Hy, LS, US, oE,

fan are always off, with Fn=0 and FF=0 the fan are always off.
FF
Fan OFF time: (0 to 15 min) with FC=Cn or CY, (fan activated in parallel with compressor). It

fan are always off, with Fn=0 and FF=0 the fan are always off.

CA
Temperature alarms configuration: (Ab; rE) Ab = absolute temperature: alarm temperature

the alarm is enabled, after the Ad delay time.
AL
Minimum temperature alarm: (-55°C to AU; -67°F to AU) when this temperature is reached
