NO = No safety door switch fitted. YES = Safety door switch fitted.
Note: Usually fitted to the evaporator fan door on Modular Blast Chillers.
P79
Door Switch 1
Determines if a door switch is fitted or not, and consequently dictates Evaporator Fan operation, UV Sanitisation
operation and door alarm activation’s. Also used to initiate the controller from the energy saving mode.
NO = No door switch fitted. YES = Door switch fitted.
P80 Door Stop
The delay period between the door being opened and the condensing unit stopping (only active if the ‘Door
Switch’ is set to ‘YES’).
00 minutes = Condensing unit stops instantaneously. 01 to 30 minutes = Delay before unit stops.
P81 Door Alarm Delay
The delay following the ‘Door Stop’ period before the door open alarm sounds. Therefore if the ‘Door Stop’ is set
for 1 minute, and the ‘Door Alarm’ is set to 5 minutes, the door alarm will sound 6 minutes after the door was
opened. (Only active if ‘Door Switch’ = YES).
00 minutes = //instantaneous door alarm. 01 to 30 minutes = Delay before alarm sounds.
P82 High Alarm Temp
The temperature at which the alarm will sound to warn that the measured air temperature value is too high. The
alarm sounding is dependent upon the selected program and the stage of the cycle. I.e. during a chill cycle if the
measured temperature is greater than or equal to program air set point temperature + chill hysteresis + high
alarm temperature value (after the appropriate alarm delay period) the alarm will sound. Similarly if the measured
hold temperature is greater than or equal to program hold set point + hold hysteresis + high alarm temperature
value the alarm will sound.
Range 1°C to 50°C.
P83 High Alarm Delay
The delay period between a temperature alarm condition occurring.
00 minutes = Instantaneous audible alarm. 01 to 120 minutes = period of delay.
P84 Alarm Time
The length of time, which the alarm will sound for an end of program cycle alarm or any other alarm warning prior
to automatically muting.
00 minutes No alarm. 01 to 120 minutes = Alarm energised period.
P85 Alarm Repeat Interval
The length of time between an acknowledged alarm being automatically muted and the alarm sounder being re-
energised.
00 minutes = No alarm reminder. 01 to 480 minutes = Alarm reminder period.
P86 Alarm Buzzer
Enables or disables the board alarm buzzer.
NO = Alarm disabled. YES = Alarm enabled.
P87 Air Probe Offset
Allows the value of the Air Probes to be offset allowing the product temperature to be accurately measured.
Range -15°C to +15°C
P88 Coil Probe Offset
Allows the value of the Evaporator Coil Probe to be offset allowing the coil temperature to be accurately
measured.
Range -15°C to +15°C.
P89 Food 1 Offset
Allows the value of Food Probe 1 to be offset allowing for the product temperature to be accurately measured.
Range -15°C to +15°C.
P90 Food 2 Enable
Determines whether a second Food Probe is fitted.
NO = No second food probe fitted. YES = Second food probe fitted.
P91 Food 2 Offset
Allows the value of Food Probe 2 to be offset allowing for the product temperature to be accurately measured.
Range -15°C to +15°C.
P92 Food 3 Enable
Determines whether a third Food Probe is fitted.
