Configuration of 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 enabled for alarm

16 - Defrosting alarms

32 - Miscellaneous

64 - Injection alarms

128 - Fuse cut out 

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 error.
