Pa. 10 / 15
Fnc Fan operating mode: 0 = cycles on / off with the compressor, OFF during defrost; 1 = continuous mode, OFF
during defrost; 2 = cycles on / off with the compressor, ON during defrost; 3 = continuous mode, ON during defrost;
4 = fan relay is used as 2
nd
compressor output
FSt Fan stop temperature: (-50÷150°C) Temperature above which the evaporator fan stops ( during the normal
refrigeration cycle )
Fnd Fan delay after defrost: (0 ÷ 250 min) The time interval between end of defrost and evaporator fans starting.
Runs concurrently with Fdt ( Drain time ). Always keep Fnd longer that Fdt.
Ot Thermostat probe calibration: ( -12.0 ÷ 12.0°C ) Adjustment for thermostat probe offset.
OE Evaporator probe calibration: (-12.0 ÷ 12.0°C) Adjustment for evaporator probe offset.
rES Display resolution : 0 = With decimal point, 1 = Without decimal point
CF Temperature measurement unit: 0 = Celsius; 1 = Fahrenheit.
Warning : If you alter the setting of parameter rES ( decimal point on / off ) re-check the settings of all temperature
related parameters – Set Point, HY, LS, US, ALU, ALL, dtE, FSt, Ot & OE, as they can be effected
COn Compressor ON time with faulty probe (0 ÷ 250 min) Emergency control if the thermostat probe fails.
This is the compressor “ON” time.
COF Compressor OFF time with faulty probe (0 ÷ 250 min) Emergency control if the thermostat probe fails.
This is the compressor “OFF” time.
tbA Alarm muting : 0 = Alarm relay remains active when alarm buzzer is muted. 1 = Alarm relay is cancelled
when alarm buzzer is muted.
dic Digital input operating mode: configures the digital input function:
0 = Starts a defrost;
1 = Input from a door switch (see parameter odc)
2 = Activates the auxiliary relay;
3 = Starts Energy Saving; (Control Point becomes Set Point +/- value in HES)
4 = Remote On/OFF. (puts the controller into standby)
5 = Generic external alarm (normal regulation continues)
6 = Serious external alarm (regulation is stopped)
diP Configurable digital input polarity:
0 : the digital input is activated by closing the circuit
1 : the digital input is activated by opening the circuit
did Time interval/delay for digital input alarm:(0
÷
255 min.) it defines the time delay between the detection and the
subsequent signalling of the alarm.
odc Compressor and fan status when open door:
0 = normal; 1 = Fan OFF; 2= Compressor OFF; 3 = Compressor and fan OFF.
oAc: Auxiliry relay configuration (0 = Alarm; 1 = Dead Band; 2 = Auxiliary)
AoP Alarm relay polarity: 0 = 13-14 closed with alarm; 1 = 13-14 open with alarm
doA: Door open alarm delay (0÷250min)
dot: Temperature alarm exclusion with door open (0÷250min)
rrd Regulation restart with door open (0=no; 1 = yes) If yes, regulation will restart when “door open” alarms
HES Temperature increase during the Energy Saving cycle : (-30,0°C
÷
30,0°C / -54÷54°F) sets the increasing
value of the set point during the Energy Saving cycle.
