when the compressor is OFF, resulting in counting the accumulated durations during which the compressor has been ON. The
defrost will start when the timer value exceeds the value of Defrost Start Time (if enabled).
Cnt: Continuous Timer = The defrost start timer will count only when the compressor is ON and resets to zero whenever the
compressor is OFF. The defrost will start when the timer value exceeds the value of Defrost Start Time (if enabled).
Defrost Start Time
The duration between the nish of a defrost cycle and the start of the next one, if not started due to temperature.
Defrost Duration
The duration of a defrost cycle, if not ended due to temperature.
Minimum Defrost Duration
The minimum allowable time for a defrost cycle. The Defrost cycle will not end until this time has elapsed regardless of whether
Defrost End Time or Defrost End Temperature has been met.
Minimum Duration Between Defrost Cycles
The minimum allowable time between the nish of one defrost cycle and the start of the next defrost cycle. The next defrost
cycle will not start until this time has elapsed regardless of whether Defrost Start Time or Defrost Start Temperature has been
met.
Defrost Start Temperature
The temperature that a defrost cycle will be initiated, assuming the FCAx3 has satised the “minimum Duration Between
Defrost Cycles” value. This will only be respected if the defrost probe is not faulty.
Defrost End Temperature
The temperature at which the defrost cycle will terminate, assuming the FCAx3 has been in defrost for longer than the
“minimum Defrost Duration” value. This will only be respected if the defrost probe is not faulty.
Enable Temperature Defrost During First Pull-Down
Select if the FCAx3 goes into defrost when rst powered up.
No: Defrost ON start-up is disabled. FCAx3 will only enter defrost according to other set defrost parameters.
Yes: Defrost will initiate once the FCAx3 is powered up.
Pre-Defrost Relays Off Delay
The duration between defrost start parameters being satised (temperature or time) and the FCAx3 entering defrost mode.
During this time the compressor will turn OFF and the outputs will act accordingly to the compressor OFF conguration.
Drip Down Relays Off Delay
The duration after the defrost end parameters have been satised before the FCAx3 will enter Drip Down Recovery Mode. Dur-
ing this period the compressor and outputs will be OFF.
Post Drip Down Recover Time Delay
The duration for the FCAx3 to remain in Drip Down Recover mode before Resuming normal operation. During Drip Down Re-
cover the compressor will turn ON and the other outputs will operate accordingly to the conguration.
Post Drip Down Recover Temperature Override
The temperature at which post drip down recover mode will terminate, if not ended due to time.
Enable Defrost Emergency Mode (when defrost probe is faulty)
Select whether the emergency defrost is active.
No = Emergency defrost is disabled. FCAx3 will resume respecting set defrost parameters.
Yes = Emergency defrost is enabled. FCAx3 will respect the below parameters.
Emergency Mode Defrost Start Time
The duration between the start of a defrost and the start of the next defrost when the defrost probe is faulty.
Emergency Mode Defrost End Time
