Probe selection for second temperature alarm: (nP; P1; P2; P3; P4) nP=no probe; Px=probe
“x”. Note: P4=Probe on Hot Key plug.
Pre-alarm threshold for second temperature alarm (absolute value): (-55.0 to 150.0°C; -67 to
302°F)
Second high temperature pre-alarm differential: (0.1 to 25.0°C; 1 to 45°F)
Second high temperature pre-alarm delay: (0 to 255 min; 255 = not used) delay time between
the detection of a condenser pre-alarm condition and the relative alarm signalling.
Second low temperature alarm: (-55.0 to 150.0°C; -67 to 302°F)
Second high temperature alarm: (-55.0 to 150.0°C; -67 to 302°F)
Second temperature alarm differential: (0.1 to 25.0°C; 1 to 45°F)
Second temperature alarm delay: (0 to 255 min; 255 = not used) delay time between the
detection of a condenser alarm condition and the relative alarm signalling.
Second temperature alarm delay at start-up: (0.0 to 24h00min, res. 10 min)
Compressor off due to second low temperature alarm: (n; Y) n = no, the compressor continues
to work; Y = yes, the compressor is switched off while the alarm is ON; in any case, the regulation
restarts after AC time at minimum.
Compressor off due to second high temperature alarm: (n; Y) n = no, the compressor
continues to work; Y = yes, the compressor is switched off while the alarm is ON; in any case, the
regulation restarts after AC time at minimum.
Differential for anti-freezing control: (-12.0 to 12.0°C; -21.0 to 21.0°F) the regulation stops if
T<SET+SAF
Alarm relay deactivation: (n; Y) n = no, it is not possible to deactivate neither the buzzer nor any
digital output set as an alarm; Y = yes, it is possible to deactivate both the buzzer and the digital
output set as an alarm.
5.1.8 Digital and analogue output configuration parameters - out
Relay output oAx configuration: (nu; CP1; dEF; FAn; ALr; LiG; AUS; db; onF; HES; Cnd;
CP2; dF2; HEt) nu=not used; CP1=compressor; dEF=defrost; FAn=ventilators; ALr=alarm;
LiG=light; AUS=auxiliary relay; onF=always ON with instrument ON; db=neutral zone;
HES=night blinds; Cnd=condenser fan; CP2=second compressor; dF2=second defrost;
HEt=heater control.
Alarm relay polarity: (oP; CL) oP = alarm activated by closing the contact; CL = alarm
activated by opening the contact
5.1.9 Digital input configuration parameters - inP
Base time for digital inputs: (SEC; Min) SEC = seconds; Min = minutes. Delay in activating the
function linked to the digital inputs.
Digital input 1 polarity: (oP; CL) oP = activated by closing the contact; CL = activated by opening
the contact.
Digital input 1 configuration: (nu; dor; dEF; AUS; ES; EAL; bAL; PAL; FAn; HdF; onF; LiG; CC;
EMt)
• nu=not used
• dor = door switch function
• dEF = defrost activation
• AUS = auxiliary output
• ES = energy saving mode activation
• EAL = external warning alarm
• bAL = external lock alarm
• PAL = external pressure alarm
• FAn = evaporator fan control
• HdF = holiday defrost
• onF = ON/OFF status change
• LiG = light output control
• CC = continuous cycle mode
• EMt = Motion sensor X-MOD
• MAP = change parameter map (between C1 and C2)
Digital inputs 1 alarm delay (base time depends on par. ibt): (0 to 255) delay between the
detection of an external event and the activation of the relative function.
Digital input 2 polarity: (oP; CL) oP = activated by closing the contact; CL = activated by opening
the contact.
