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

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
