Drip-off time
Here you set the time that is to elapse from a defrost and until the compressor is to
start again. (The time when water drips off the evaporator).
d06
DripOff time
Delay of fan start after defrost
Here you set the time that is to elapse from compressor start after a defrost and until
the fan may start again. (The time when water is “tied” to the evaporator).
d07
FanStartDel
Fan start temperature
The fan may also be started a little earlier than mentioned under “Delay of fan start
after defrost”, if the defrost sensor S5 registers a lower value than the one set here.
d08
FanStartTemp
Fan cut in during defrost
Here you can set whether fan is to operate during defrost.
0: Stopped (Runs during pump down)
1: Running (stopped during "fan delay")
2: Running during pump down and defrost. After that stopped
d09
FanDuringDef
Defrost sensor
Here you define the defrost sensor.
0: None, defrost is based on time
1: S5
2: S4
3: Sx. For application 1 to 8 and 10 defrosting is stopped when both S5 and S6 have
reached the set temperature. For application 9 defrosting is stopped individu

d10
DefStopSens.
Pumpdown delay
Set the time where the evaporator is emptied of refrigerant prior to the defrost.
d16
Pump dwn del.
Drain delay (only in connection with hotgas)
Set the time where the evaporator is emptied of condensed refrigerant after the
defrost.
d17
Drain del
Defrost on demand – aggregate refrigeration time
Set here is the refrigeration time allowed without defrosts. If the time is passed, a
defrost will be started.
With setting = 0 the function is cut out.
d18
MaxTherRunT
Delay on stop of heating in the drip tray
The time applies from the time the defrost stops by time or temperature to the time
the heating element in the drip tray needs to be disconnected.
d20
Drip Tray del
Adaptive defrosting
An adaptive defrosting is an extra defrost in addition to the scheduled defrosts. Here
the adaptive defrost is set for when it can start a defrost if the need arises:
0: Never
1: Only alarm on ice over
2: It may only start during day operation
3: It may start both during day and night operation
4: It can only start during night operations
d21
AD mode
Restart of adaptive defrosting
The function starts a defrost and when it is complete, the tuning function restarts so
that the evaporator’s data can be registered.
MUST ONLY BE ACTIVATED DURING STANDARD OPERATION.
d22
AD reset
If you wish to see the temperature at the defrost sensor, push the controller’s lower
-
most button. (May be changed to another function in o92.)
Defrost temp.
If you wish to start an extra defrost, push the controller’s lowermost button for four
seconds.
You can stop an ongoing defrost in the same way
Def Start
Here you can start a manual defrost
Hold After Def
Shows ON when the controller is
operating with coordinated defrost.
Disable def.
Defrost in progress can be stopped
Defrost State
Status on defrost
1= pump down / defrost
Parameter for cooling function
Integration time
Expert setting for injection function
The value should only be changed by specially trained staff.
n05
Tn sec
Max. value for the superheat reference
n09
Max SH
Min. value for the superheat reference
n10
Min SH
MOP temperature
If no MOP function is required, select pos. OFF
n11
MOP temp
(A value of 15 corresponds to OFF)
Temperatureglide (only when using of S1-temperature sensor)
If a zeotrope refrigerant is used, a value for temperature glide must be set.
