Thermostat override: (0 to 990min; res. 10min) period during which the compressor will run continuously, irrespective of
temperature. Setting this parameter to 0 inhibit this function.
Set point for continuous cycle: (-55 to 150 °C or -67 to 302°F) it sets the set point used during the continuous cycle.
Defrost delay after fast freezing: (0 to 255min) time interval between the end of the thermostat override period and the
start of the following defrost related to it.
Interval between defrosts: (0 to 255hours) time interval between the beginning of two consecutive defrosts.
Delay start of defrost: (0 to 255min) delay between reaching the defrost interval time (as defined by parameter idF) and the
defrost actually starting. Used to stagger defrosts between multiple systems.
(Maximum) duration of defrost: (0 to 255min) time duration of defrost when only one probe is in use, or defrost time out
override when second (evaporator) probe is in use. Set it to zero to disable defrost cycles.
Defrost termination temperature: (-55 to 50°C or -67 to 122°F) sets the defrost termination temperature. Measured by the
evaporator probe.
(Maximum) length for second defrost: (0 to 255min) when P3P = 0, (not evaporator probe: timed defrost) it sets the
defrost duration, when P3P = 1 (defrost end based on temperature) it sets the maximum length for defrost.
Note: The P3 probe will be automatically set as second evaporator probe by the tC parameter.
Second termination temperature: (-55 to 50°C or -67 to 122°F) sets the temperature measured by the second evaporator
probe (P3), which causes the end of defrost.
Display during defrost:
Defrost display time out: (0 to 250min) after a defrost, the controller will revert to current temperature display when the
temperature is back down within its normal working range, or after the time set in this parameter, whichever is the sooner.
Defrost type:
Drain down time: (0 to 255min) drain down time. Runs concurrently with Fnd (Fan delay after defrost time).
First defrost after power-on:
Fan operating mode:
Fan stop temperature: (-55 to 50°C or -67 to 122°F) temperature above which the evaporator fan stops (during the normal
refrigeration cycle).
