Warning

Please Note
Maximum time period allowed for defrosting if termination temperature is not reached.
A period after defrost max to allow the draining of any surplus water
The compressor(s) is switched on at the start of this period to allow the temperature to recover to the
normal operating point. This period also inhibits the OT alarm.
Note that if the air-off temperature is still above the OT alarm setpoint when this period expires, an
immediate OT alarm occurs; there is not a further alarm delay.
Time period before the defrost min period to allow for a pump down
This parameter allows the fans start after a drain-down period to be delayed, either by time (P-49) or
when the temperature point (P-88) is reached. This parameter uses the same probe strategy as the
defrost terminate.
Time after a drain-down period before the fans start if P-86 is set to time
Temperature at which the fans start after a drain-down period when P-86 is set to temperature.
Allows the user to set the fans on or off in defrost.
Note if the fans are set to on in defrost, they will go off for the drain-down period and then follow the P-86
rules.
Electric – Defrost heater will go off during defrost min. period, if defrost termination is achieved, and will
stay off.
Electric CIn – Defrost heater will go off during defrost min. period if defrost termination is achieved but will
then cycle on and off around the termination temperature setpoint until the end of the defrost min. period.
Gas - If gas is selected, the compressor is kept running for the duration of the defrost cycle.
Turns the defrost hold feature on and off. When switched on, the controller can be held in defrost until a
remote command from the front end starts the recovery process.
Allows user to enable/disable defrost skip. This feature allows the controller to skip defrosts. If the current
defrost terminates on temperature then the controller will skip the next scheduled defrost providing the
previous defrost terminated before the defrost skip time (P-96). Operates only when the controller is set to
local defrost scheduling.
Time factor used in defrost skip. The previous defrost has to terminate before this value expires to allow
the controller to skip a defrost.
Allows the user to set the lights mode: -

Always off

Always on

Use a local schedule P-61 to P-74)
