Note: The fan 1 hold operation does not effect routine defrost operation.
P66 FAN 2 Hold Operation
Determines the evaporator fan relay energisation during ‘Hold’ mode.
‘OFF’ = Evaporator fan 2 relay is not energised in ‘Hold’.
‘CYCLE’ = Evaporator fan 2 relay cycles with condensing system relay in ‘Hold’.
‘AUTO’ = Evaporator fan 2 relay cycles with condensing system and fan hysteresis in ‘Hold’.
‘ON’ = Evaporator fan 2 relay is always energised in ‘Hold’.
Note: The fan 2 hold operation does not effect routine defrost operation.
P67 Capacity Enable
Determines if Capacity Control is enabled.
‘OFF’ = Capacity is disabled.
‘AUTO’ = Capacity is enabled in chill and hold modes in conjunction with Capacity Hysteresis.
‘ON’ = Capacity is enabled (in hold mode only).
P68 Capacity Hysteresis
The differential value at which capacity control is de-energised.
Capacity control is disabled during the chill hold cycle (Capacity Enable set to ‘Auto’) if the temperature =
program air set point + chill hysteresis + capacity hysteresis (rising from chill set point). During hold (Capacity
Enable set to ‘Auto’ or ‘On’) if the temperature = hold air set point + hold hysteresis + capacity hysteresis (rising
from hold air set point).
Range 2°C to 20°C.
P69 Defrost Type
Identifies the type of defrost cycle to be initiated either standard or manually.
OFF = Off cycle defrost. ELE = Electric defrost. GAS = Hot gas defrost.
P70 Smart Defrost Inc
DO NOT ADJUST.
P71 Defrost End Time
The length of time that the Defrost period will last before reverting to the chill or hold cycle.
Range 01minute to 60 minutes.
P72 Defrost End Temp
The coil temperature as detected by the evaporator probe at which the Defrost function will terminate before
reverting back to chill or hold mode.
Range 0°C to 10°C.
P73 Drain Time
The time period following the defrost routine (terminated by time or temperature) that is allowed for ‘melt water’ to
drain from the evaporator coil prior to the condensing system restarting.
00 = No drain down time. 01 to 30 = Drain down period in minutes.
P74 Fan delay Temp
The temperature the evaporator coil must reach following a defrost before the evaporator fan/s are allowed to re-
start.
Range -15°C to 15°C.
P75 Duty Cycle
The percentage time that the condensing system will operate in order to maintain Hold temperature in the event
of an air probe failure.
Range 0% to 100%.
P76 Comp. Rest Time
The forced rest period before the condensing system can be energised from when it was de-energised.
00 = Excludes compressor rest period. 01 to 30 = Compressor rest period in minutes.
Note: This is not a compressor start delay.
P77 HP Switch
Terminates the condensing system in the event of a high pressure developing in the refrigeration system as a
result of, to high food temperature, condenser fan failure, blocked condenser, air flow restriction etc.
Automatically re – sets when the normal working pressure is achieved.
YES = enabled. NO = disabled.
P78 Door Switch 2
Determines if a safety door switch is fitted. If enabled this will not allow any chill, defrost or UV Sanitisation
programs to be run if the door is open.
