dtY Defrost type selection (timed , electric, hot gas off cycle). Range 0 to 3.
0 = Timed defrost.
1 = Electric defrost.
2 = Hot gas defrost.
3 = Off cycle.
dt: Drain down time. After the defrost has been completed the compressor and evaporator fan stay off for the
duration of the fan delay period. Range 0 to 250 minutes.
dSt: Defrost termination temperature. The temperature at which the defrost relay is de-energised.
Range -50°C to +150°C
Fans rE3 menu. FAn
Fdt: Fan delay time. Time in minutes to delay the evaporator start after a defrost. Range 0 to 15 minutes.
FCO: Evaporator fan/s runs continuously. Allows selection of the fans to cycle with the compressor or to run
continuously. Range Y for fan/s to run continuously or N for fan/s to cycle with the compressor.
dFd: fan/s stops during defrost. Allows for the option of the fan/s to run during defrost or to stop during defrost.
Range N to run during defrost or Y to stop during defrost.
Fod: Fan/s OFF when door opened. Allows selection of the fan/s to run or not when the door is opened.
Range on for fan/s to run during door openings, no for fan/s to stop during door openings.
Fst: Fan/s stop temperature. Allows the setting of the temperature that fan/s will be stopped at. The fan/s will
remain off as long as the value read by the defrost probe (placed on the evaporator) is higher than the set
temperature value.
Room Light rE4 menu. LUc
No parameters.
Temperature Alarms rE5 menu. ALP
LAL: Low temperature alarm. In the event of the air temperature dropping below the low temperature set point
the alarm will sound and the alarm relay will be energised. The alarm set point is the value from the air
temperature set point. Warning: the LAL parameter must be set to a negative value. Range HAL -50°C
HAL: High temperature alarm. In the event of the air temperature going higher than the high temperature set
point the alarm will sound and the alarm relay will be energised. The alarm set point is the value from the
air temperature set point.
AFd: alarm differential. Range -12°C to +12°C.
PAO: Alarm delay after start up. Temperature alarms are overridden, in hours, when the unit is switched
on. Range 0 to 10 hours.
dAo: Alarm delay after defrost. Temperature alarms are overridden, in minutes, after defrost.
Range 0 to 250 minutes.
OAO: Alarm delay after opening. Temperature alarms are overridden, in hours, after door closure.
Range 0 to 10 hours.
Pressure Alarms rE6 menu. PP
PEI: Time period for pressure trips. Time interval during which the number of times the high pressure trip is
activated for an alarm condition to occur and the subsequent stopping of the compressor.
Range 1 to 99 minutes.
Pen: Number of high-pressure trips.
Number of high-pressure trips during the time as set in PEI for an alarm condition to be activated with the
subsequent stopping of the compressor.
Range 0 to 15.
Condensing Temperature Alarms rE7 menu. ALP
AL: Maximum condensing temperature alarm setpoint.
In the event of the Condenser temperature going higher than the condenser temperature set point the
alarm will sound and the alarm relay will be energised.
Range 0°C to 99°C.
Afd: Alarm Differential.
Allowable temperature rise between alarm activation and de-activation.
Range -12°C to +12°C
