Table 7-1 - List of Parameters
12 • XR75CX I&O Manual
n = no: compressor keeps on working
Y = yes, compressor is switched OFF until the alarm is present, in any case regulation
restarts after Ac time at minimum.
AUXILIARY RELAY
n= silencing disabled: alarm relay stays ON until alarm condition lasts
y =silencing enabled: alarm relay is switched OFF by pressing a key during an alarm
dEF, FAn: do not select it! ALr: alarm; Lig: light; AUS: Auxiliary relay; onF: always
ON with device ON; db= neutral zone; cP2 = do not select it!; dEF2: do not select it!;
HES: night blind
Set if the alarm relay is open or closed when an alarm happens.
CL= terminals 1-4 closed during an alarm
oP = terminals 1-4 open during an alarm
DIGITAL INPUTS
oP = the digital input is activated by opening the contact
CL = the digital input is activated by closing the contact
dor = door switch function
dEF = activation of a defrost cycle
oP = the digital input is activated by opening the contact
CL = the digital input is activated by closing the contact
EAL= external alarm: "EA" message is displayed
bAL= serious alarm "CA" message is displayed
PAL= pressure switch alarm, "CA" message is displayed
dor = door switch function
dEF= activation of a defrost cycle
ES = energy saving
AUS = auxiliary relay activation with oA3 = AUS
Htr = kind of action inversion (cooling – heating)
FAn = fan
HdF = Holiday defrost (enable only with RTC)
onF = to switch the controller OFF
Delay between the detection of the external alarm condition and its signaling. When i2F
= PAL: time for pressure switch function: time interval to calculate the number of the
pressure switch activation.
(0 to 255 min)
(0 to 15)
Number of activation of the pressure switch, during the did interval, before signaling
the alarm event (i2F = PAL). If the nPS activation in the did time is reached, switch
OFF and ON the device to restart normal regulation.
no = normal
Fan = fan OFF
CPr = compressor OFF
F_C = compressor and fan OFF
no = outputs not affected by the doA alarm
yES = outputs restart with the doA alarm
(-30.0°C to 30.0°C)
Sets the increasing value of the setpoint during the Energy Saving cycle.
Sets the current hour.
Sets the current minute.
Sets the current day of the week.
Set the first day of the week that follows the holiday times.
