AC2 Compressor OFF with high
temperature alarm of condenser
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
tbA Alarm relay silencing (with
oA3=ALr)
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
oA3 Fourth relay configuration (1-4) 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
AOP Alarm relay polarity 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
i1P Digital input polarity (18-20) oP = the digital input is activated by opening the contact
CL = the digital input is activated by closing the contact
i1F Digital input configuration (18-
20)
dor = door switch function
dEF = activation of a defrost cycle
i2P 2nd digital input polarity (18-
19)
oP = the digital input is activated by opening the contact
CL = the digital input is activated by closing the contact
i2F 2nd digital input configuration
(18-19)
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
did (0 to 255 min) with i2F= EAL
or i2F = bAL digital input
alarm delay (18-20)
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.
doA Door open signaling delay (0 to 255 min)
nPS Pressure switch number (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.
Odc Compressor status when open
door
no = normal
Fan = fan OFF
CPr = compressor OFF
F_C = compressor and fan OFF
rrd Outputs restart after doA alarm no = outputs not affected by the doA alarm
yES = outputs restart with the doA alarm
HES Temperature increase during
the Energy Saving cycle
(-30.0°C to 30.0°C)
Sets the increasing value of the setpoint during the Energy Saving cycle.
TO SET CURRENT TIME AND WEEKLY HOLIDAYS (ONLY FOR MODELS WITH RTC)
Hur Current hour (0 to 23 hr) Sets the current hour.
Min Current minute (0 to 59 min) Sets the current minute.
dAY Current day (Sun to SAt) Sets the current day of the week.
Hd1 First weekly holiday (Sun to
not used)
