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
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.
