Start-up time for signal reliability
Should only be changed by trained staff.
Stability factor for superheat control.

Forced closing. AKV valve shut in pos. ON
Fan
Fan stop on compressor cut out
Delayed fan stop when compressor is cut out
Safety function. The fan stops if the S5 tem-
perature reaches this value
Miscellaneous
Delay of output signal after start-up
Define digital input signal (DI:
OFF=not used, 1=Door alarm, 2=defrost start,
3=Night operation, 4=External start/stop, 5 =
Coordinated defrost with cable connections,
6 = door function
Network address (range = 0-60)
ON/OFF switch (service-pin message)
Access code
Used sensor type for S3, S4 and S5 (Pt / PTC)
Set supply voltage frequency
Define digitalt output signal (DO:
0=not used
Coordinated defrost with cable connections:
1=Master, 2= Slave

Manual control of outputs:
OFF=No override
1: Compressor reay is ON (railheat relay = ON)
2: Defrost relay is ON
3: Fan relay is ON
4: Alarm relay is OFF (Railheat relay = on)
5: DO output is ON
6: AKV output is ON
7: Light relay is ON (Railheat relay = on)
When manual control is terminated, the set-
ting must be changed to OFF

value
Inject-ON definition
When the ON input is cut out refrigeration is
stopped.
Here you define how the fan relay and the
alarm function are to act:
1 = Fan relay = ON, alarm monitoring active
2 = Fan relay = OFF, alarm monitoring active
3 = Fan relay = OFF, no alarm monitoring
4 = Fan relay = ON, no alarm monitoring
5 to 8= as 1 to 4, but without connection to
terminal 40-41.

If you need to return to the factory-set values, it can be done in this way:
- Cut out the supply voltage to the controller
- Keep both buttons depressed at the same time as you reconnect the supply voltage
