Set Point 2 regulation (for condenser fan): (-55 to 50°C; -67 to 122°F) setting of temperature
St2
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
HY2
ventilator regulator
Condenser fan operating mode: (Cn; on; CY; oY)
•
Cn = runs with the compressor and OFF during defrost
•
FCC on = continuous mode, OFF during defrost
•
CY = runs with the compressor and ON during defrost
•
oY = continuous mode, ON during defrost
Fd3 Condenser fan activation delay: (0 to 255 sec) delay before activating condenser fan
Fd4 Condenser fan deactivation delay: (0 to 255 sec) delay before deactivating condenser fan

5.1.6 Auxiliary regulator parameters - AUS

ACH 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
SAA
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.
•
SHY 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
ArP
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
Sdd
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
btA
time is in minutes.
Ato Interval of time with auxiliary output ON: 0 to 255 (base time defined in par. btA)
AtF 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:
ALP
P4=Probe on Hot Key plug.
ALC 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.
ALU
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.
ALL
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.
•
AFH 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
ALd
and the relative alarm signalling.
Temperature alarm delay when door open: (0.0 to 24h00min, res. 10 min) delay time between
dot 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
dAo detection of a temperature alarm condition and the relative alarm signalling, after starting up the
instrument.
Probe selection for second temperature alarm: (nP; P1; P2; P3; P4) nP=no probe; Px=probe
AP2
"x". Note: P4=Probe on Hot Key plug.
