"dot"
Drip OFF Time
This parameter can be set to between 0 and 60 minutes and defines how long the delay is between the heater being switched
Min. 0 min
OFF and the compressor starting again.
Max. 60 min
Default 0 min
"Fdd"
Fan Delay after Defrost
Defines how long the delay is between the start of the compressor after defrost and the fan starting again.
Min. 0 s
Max. 600 s
Default 0 s
"Ftd"
Fan Start Temperature
This only applies if an evaporator temperature sensor is fitted.
Min. -25.0°C
This parameter determines at what evaporator temperature the fan will start after a defrost cycle is complete.
Max. 25.0°C
Default 25.0°C
If the time set in "Fdd" occurs before the temperature set in "Ftd", the fan will start in line with "Fdd". If the temperature set in "Ftd"
occurs first, then the fan will start in line with "Ftd". It is therefore a case of whichever parameter's setting is reached first which
determines when the fan starts.
"dFA"
Defrost Fan On
Set to "yES", the fan will constantly run during defrost cycles.
Min. no
Set to "no", the fan will not run during defrost cycles.
Max. yes
Default no
"dCt"
Defrost ON Compressor Time
If Yes: Defrost time based on actual accumulated compressor ON time"doC"
Min. no
If NO: Defrost Times based on elapsed time.
Max. yes
Default no
"doC"
Defrost by Comp. running time
Continuous compressor running can cause defrost.
Min. 0 hour
"0" = deactived
Max. 24 hour
Default 0 hour
"dEt"
Defrost start evaporator temp
Defrost will get triggered at this temperature after expiry of minimum defrost interval "dii" (adaptive defrost only).
Min. -50.0°C
Max. 0.0°C
Default -50.0°C
"ddt"
Defrost Δt
Defrost Δt compare with evaporator temperature of first cut out after
Min. 0.0 K
defrost to trigger defrost start.
Max. 30.0 K
The defrost start if evaporator temperature has decreased more the "ddt"
Default 5.0 K
"idi"
Initial Defrost Interval
The initial defrost interval determines the time for first defrost after power-up. The initial defrost is mainly intended for factory
Min. 0 hour
testing of the defrost functionality and can be set to expire after a number compressor cycles according to the setting of parameter
Max. 96 hour
Default 3 hour
idd. During normal operation, the defrost counter will be saved in memory and restored after power loss, making the initial defrost
unnecessary.
"idd"
Initial Defrost Duration
The initial defrost duration is the number of compressor cycles before the initial defrost is deactivated.
Min. 0
"0": "idi" No initial defrost.
Max. 999
Default 100
"1-998": number of compressor cycles before deactivation.
"999": initial defrost always active.
