Configuration of the alarm relay
The alarm relay will be activated upon an alarm signal from the following groups:
1 - High temperature alarms
2 - Low temperature alarms
4 - Sensor error
8 - Digital input is activated for alarm
16 - Defrost alarms
32 - Miscellaneous
The groups that are to activate the alarm relay must be set by using a numerical value
which is the sum of the groups that must be activated.
(E.g. a value of 5 will activate all high temperature alarms and all sensor errors. 0 will cancel
the relay function)

Forced control
If you need to force-control an output, you should set r12 to -1 (manual mode). You should then select the relevant relay function, e.g. u58. Go
to the function by pressing the middle button. Select On.
