Enable Defrost Function
Select whether defrost is active.
No = Defrost is disabled. All defrost parameters become de-active and the FCAx3 will not go into defrost.
Yes = Defrost is enabled. FCAx3 will act according to the set parameters.
Compressor Operation On During Defrost
Select if the compressor is ON during defrost mode.
No = Compressor will turn OFF (if ON) and remain OFF during defrost.
Yes = Compressor will turn ON (if OFF) and remain ON during defrost (for Hot Gas defrost).
Defrost Temperature Probe
Select the temperature probe used to determine the defrost by temperature function.
None = Defrost will start and end with time only.
Probe 1 = Regulating probe connected to P1.
Probe 2 = Probe connected to P2. Only available if 2 is selected from “Number of Temperature Probes”.
Enable Immediate Defrost at Power Up
Select whether defrost is entered immediately when the FCAx3 is powered ON.
No = FCAx3 will operate normally on power-up according to set parameters and will only enter defrost when other defrost
conditions are satised.
Yes = Defrost starts on power-up depending on the Immediate Defrost Enable Temperature.
Immediate Defrost Enable Temperature
The maximum temperature sensed by the defrost probe at power-up for defrost to be entered. If set to N/A, the FCAx3
will enter defrost mode at power-up regardless of the defrost temperature.
Note: Immediate defrost will not terminate with defrost end temperature, it will ONLY be terminated when defrost duration has
been satised. If the defrost duration is set to N/A, immediate defrost will terminate after 10 minutes.
Note: Immediate defrost is intended for production tests only and not for eld operation. Ensure this is disabled for eld units.
Inhibit Defrost until First Pull-down Event
Select whether defrost is enabled during the rst pull-down event. The First pull-down event nishes when the compressor
cycles OFF for the rst time due to the temperature dropping below the cut-out value.
No = Defrost is enabled. Defrost can take place during the rst pull-down event if dened defrost conditions are met.
Yes = Defrost is disabled. Defrost will not take place until the rst pull-down event has nished.
Inhibit Defrost Temperature (using Regulation Probe)
The regulation temperature sensed after a power-up event, below which defrost will not be inhibited anymore.
Duration Defrost is inhibited
The duration of the rst pull-down event and therefore the period of defrost will be inhibited. After this time the FCAx3
will resume normal operation and defrost will be enabled as per the set parameters.
Defrost Enable Temperature
Select whether defrost is disabled depending on the regulation probe temperature.
No = Defrost is enabled regardless of the regulation probe and will be initiated by the set parameters.
Yes = Defrost will be disabled if the regulation temperature is above the set temperature even if other defrost parameters are
satised. If the regulation temperature is below the set value, defrost will be initiated as normal.
Absolute Temperature (using Regulation Probe)
The maximum regulation temperature before the defrost function is disabled.
Degrees Above Cut-in (using Regulation Probe)
The temperature differential between the cut-in temperature and the regulation temperature that the defrost function
will be disabled.
Defrost Start Timer Type
Select the type of timer to start a defrost cycle.
rEL: Real-Time = The defrost start time will continuously count regardless of whether the compressor is ON or OFF and the
defrost will start when the timer value exceeds the value of Defrost Start Time (if enabled).
aCC: Accumulated Time = The defrost start timer will count only when the compressor is ON and stops counting (not resetting)
