Parameter Definitions
REGULATION
Hy Intervention differential for set point: (0,1 ÷ 12,0 /0,1°C/1°F), always positive. Compressor cut IN is Set Point
Plus Differential (Hy). Compressor cut OUT is when the temperature reaches the set point.
AC Anti-short cycle delay: (0÷30 min) minimum interval between the compressor stop and the following
restart.
1c2 Second compressor setting: (enabled only if OAC=C2)
The fourth relay work as second compressor if OAC=Co2.
Second compressor operates on set + OAS. (whit set= set loaded during the current phase). It starts oAt min.
after the first compressor
The following table shows how it works:

rPO Thermostat probe calibration (-12,0 ÷ 12,0; res. 0,1 °C /1°F)
EPP Evaporator probe presence (not present in the XB350C): (no / YES) no: not present (timed defrost); YES:
present (end defrost )
EPO Evaporator probe calibration (not present in the XB350C): (-12,0 ÷ 12,0; res. 0,1 °C /1°F)
iPP Insert probe presence (no / YES) no: not present; YES: present.
iPO Insert probe calibration (-12,0 ÷ 12,0; res. 0,1 °C /1°F)
CFTemperature measurement unit: °C =Celsius; °F =Fahrenheit
rES Resolution (for °C): in: integer; de: with decimal point
PAU Time of stand by: (0 ÷ 60min) after this time the controller restart the cycle
PFt Maximum acceptable duration of power failure: (0 ÷ 250 min) if power failure duration is less than PFt,
the cycle restarts from the same point at which it was stopped otherwise the cycle restarts from the beginning of
the current phase.
iPd Temperature difference for the automatic recognition of the insert probe: (0 ÷ 30; ris.1 °C/1°F) if the
difference of temperature between the insert probe and the thermostat probe is less than iPd, the selected cycle
is made by time.
iPt Time delay for the automatic recognition of the insert probe: (0÷255sec, with 0 only timed cycles are done)
time between the start of a cycle and the comparison of the temperature of the thermostat probe and the insert
probe to recognising if the insert probe is used.
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
diC Digital input operating mode (EAL, bAL, dor)
EAL: external alarm; bAL: serious alarm; dor: door open function
diP: digital input polarity: (OP÷CL)select if the digital input is activated by opening or closing the contact. OP=
opening; CL=closing
did: digital input delay (0÷255 min) delay between digital input activation and his signalling for configurable or
door opened alarm.
NOTE: with diC=EAL did has to be different from zero.
