dEF la- b el)
(0 to 255 min) S ets the maximum time between the end of defrost and the
restarting of the real room t emperature display.
(0 to 120 min) T ime interval between reaching defrost termination
temperature and the restoring of the c ontrollers normal operation. This time
allows the evaporator to eliminate water drops t h at might have formed due
to defrost.
(y = immediately; n = after the IdF time)
(0 to 23.5 hr) T ime interval between the end of the fast freezing cycle and the
following defrost related t o it.
FANS
C-n = runs with the compressor, OFF during defrost O-n = continuous mode,
OFF during defrost C -y = runs with the compressor, ON during defrost
O-y = continuous mode, ON during defrost
(0 to 255 min) Interval between end of defrost and evaporator fans start
(0 to 59°C; FCt = 0 function disabled) I f the difference in temperature
between the evaporator and the room probes is more t han the value of the
FCt parameter, the fans are switched ON.
(-50 to 50°C/ 122°F) Setting of temperature, detected by the evaporator
probe, above which fans are always OFF.
(0 to 15 min) With Fnc=C_n or C_y, (fan activated in parallel with
compressor). Sets the evaporator f an ON cycling time when the compressor is
OFF. When Fon=0 and FoF not equal to 0, the fans are always OFF, with
Fon=0 and FoF=0, the fans are always OFF.
(0 to 15 min) W ith Fnc=C_n or C_y, (fan activated in parallel with compressor).
Sets the evaporator f an OFF cycling time when the compressor is OFF. When
Fon=0 and FoF not equal to 0, the fans are always OFF, when Fon=0 and
FoF=0, the fans are always OFF.
nP = no probe P 1 = thermostat probe P2 = evaporator probe
configurable probe P 4 = probe on Hot Key plug
Ht = heating C L = cooling
(-100 to 150.0°C; -148 to 302°F) Defines the room temperature setpoint to
switch auxiliary relay.
(0.1 to 25.5°C/ 1 to 255°F) I ntervention differential for auxiliary output
setpoint. When ACH = CL, AUX Cut in is SAA + SHy; AUX Cut out is SAA
W hen ACH = Ht , AUX Cut in is SAA - SHy; AUX Cut out is SAA
nP = no probe, the auxiliary relay is switched only by the digital input
Probe 1 (thermostat probe) P2 = Probe 2 (evaporator probe)
Probe 3 (display probe) P4 = Probe 4
n = the auxiliary relay operates during defrost

ALARMS
nP = no probe, the temperature alarms are disabled P 1 = Probe 1
(thermostat probe) P2 = Probe 2 (evaporator probe) P3 = Probe 3 (display
probe) P4 = Fourth probe
(Ab; rE) Ab = absolute temperature: alarm temperature is given by the ALL or
ALU values. rE = temperature alarms are referred to the setpoint.
Temperature alarm is enabled when t he temperature exceeds the SEt + ALU or
SEt - ALL values.
(SEt to 150°C; SEt to 302°F) W hen this temperature is reached, the alarm is
enabled, after the ALd delay time.
(-100 to SEt; -148°C to 230°F) W hen this temperature is reached, the alarm is
enabled, after the ALd delay time.
(0.1 to 25.5°C; 1 to 45°F) I ntervention differential for recovery of
temperature alarm. It is also used for the restart o f the fan when the FSt
temperature is reached.
(0 to 255 min) T ime interval between the detection of an alarm condition
and alarm signaling.
(from 0.0 min to 23.5 hr) T ime interval between the detection of the
temperature alarm condition after device p ower ON and alarm signaling.
CONDENSER TEMPERATURE ALARM
nP = no probe P1 = thermostat probe P2 = evaporator probe P 3 =
configurable probe P 4 = probe on Hot Key plug
(-100 to 150°C) When this temperature is reached, the LA2 alarm is signaled,
possibly after the Ad2 de l ay.
(-100 to 150°C) W hen this temperature is reached, the HA2 alarm is signaled,
possibly after the Ad2 de l ay.
(0.1 to 25.5°C; 1 to 45°F)
(0 to 255 min) T ime interval between the detection of the condenser alarm
condition and alarm signal i ng.
(from 0.0 min to 23.5 hr, res. 10 min)
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.
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 O N with device ON; db= neutral zone; cP2 = do not select it!; dEF2: do
not select it!; H ES: 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
input is activated by closing the contact
dor = door switch function d EF = 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 b AL= serious alarm "CA"
message is displayed P AL= pressure switch alarm, "CA" message is displayed
d or = 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) o nF = 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 p ressure switch activation.
(0 to 255 min)
(0 to 15) Number of activation of the pressure switch, during the did interval,
before signaling t he alarm event (i2F = PAL). If the nPS activation in the did
time is reached, switch O FF and ON the device to restart normal regulation.
