Evaporator fan OFF time in normal mode (with compressor OFF): (0 to 255 min) used when
energy saving status is not active.
Evaporator fan ON time in energy saving mode (with compressor OFF) (0 to 255 min) used
when energy saving status is active.
Evaporator fan OFF time in energy saving mode (with compressor OFF): (0 to 255 min) used
when energy saving status is active.
Evaporator fan delay: (0 to 255 sec) delay before activating evaporator fan
Evaporator fan delay after closing door: (0 to 255 sec) delay before activating evaporator fan
and after closing the door
Probe selection for condenser fan: (nP; P1; P2; P3; P4) nP=no probe; Px=probe “x”. Note:
P4=Probe on Hot Key plug.
Set Point 2 regulation (for condenser fan): (-55 to 50°C; -67 to 122°F) setting of temperature
detected by evaporator probe. Above this value of temperature fans are always OFF.
Set Point 2 differential (for condenser fan): (0.1 to 25.5°C; 1 to 45°F) differential for evaporator
ventilator regulator
Condenser fan operating mode: (Cn; on; CY; oY)
• Cn = runs with the compressor and OFF during defrost
• on = continuous mode, OFF during defrost
• CY = runs with the compressor and ON during defrost
• oY = continuous mode, ON during defrost
Condenser fan activation delay: (0 to 255 sec) delay before activating condenser fan
Condenser fan deactivation delay: (0 to 255 sec) delay before deactivating condenser fan
5.1.6 Auxiliary regulator parameters - AUS
Type of control for auxiliary regulator: (Ht; CL) Ht = heating; CL = cooling.
Set Point for auxiliary regulator: (-55.0 to 150.0°C; -67 to 302°F) it defines the room temperature
set point to switch auxiliary relay.
Auxiliary regulator differential: (0.1 to 25.5°C; 1 to 45°F) differential for auxiliary output set point.
• ACH=CL, AUX Cut in is [SAA+SHY]; AUX Cut out is SAA.
• ACH=Ht, AUX Cut in is [SAA–SHY]; AUX Cut out is SAA.
Probe selection for auxiliary regulator: (nP; P1; P2; P3; P4) nP = no probe, the auxiliary relay is
switched only by the digital input; Px=probe “x”. Note: P4=Probe on Hot Key plug.
Auxiliary regulator disabled during any defrost cycle: (n; Y) n = the auxiliary relay operates
during defrost. Y = the auxiliary relay is switched off during defrost.
Base time for parameters Ato and AtF: (SEC; Min) SEC = base time is in second; Min = base
time is in minutes.
Interval of time with auxiliary output ON: 0 to 255 (base time defined in par. btA)
Interval of time with auxiliary output OFF: 0 to 255 (base time defined in par. btA)
5.1.7 Alarm configuration parameters
Probe selection for temperature alarms: (nP; P1; P2; P3; P4) nP=no probe; Px=probe “x”. Note:
P4=Probe on Hot Key plug.
Temperature alarms configuration: (Ab, rE) Ab = absolute; rE = relative.
High temperature alarm: when this temperature is reached, the alarm is enabled after the Ad
delay time.
• If ALC=Ab → ALL to 150.0°C or ALL to 302°F.
• If ALC=rE → 0.0 to 50.0°C or 0 to 90°F.
Low temperature alarm: when this temperature is reached, the alarm is enabled after the Ad
delay time.
• If ALC=Ab → -55.0°C to ALU or -67°F to ALU.
• If ALC=rE → 0.0 to 50.0°C or 0 to 90°F.
Temperature alarm differential: (0.1 to 25.0°C; 1 to 45°F) alarm differential.
Temperature alarm delay: (0 to 255 min) delay time between the detection of an alarm condition
and the relative alarm signalling.
Temperature alarm delay with open door: (0.0 to 24h00min, res. 10 min) delay time between the
detection of a temperature alarm condition and the relative alarm signalling, after starting up the
instrument.
Temperature alarm delay at start-up: (0.0 to 24h00min, res. 10 min) delay time between the
detection of a temperature alarm condition and the relative alarm signalling, after starting up the
instrument.
