Defrost Start
When defrost mode is set to “Local”, this is the start time for the 1
st
defrost
Defrost Number
When defrost mode is set to “Local”, this is the number of defrosts per day equally spaced
from the start time.
No Defrost Time
If the controller misses a defrost command for any reason, a defrost will initiate after this
time has elapsed from the last defrost. Normally set to 2 hours over the normal defrost
period.
Def. term. temp.
The defrost will terminate when the temperature of the air off probe(s) reaches this value.
Defrost min time
Minimum time that a defrost will use. Defrost can’t terminate until this time has elapsed. If
termination temperature is reached during this period the controller will not continue the
refrigeration cycle until the end of the defrost min period.
Defrost max time
Time period after defrost minimum that defrosts are allowed to terminate.
Drain down time
A period after defrost period to allow the draining of any surplus water.
Recovery time
The valve 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.
