C23 ALRM Alarm mode:

0: No Alarms generated, no control action on event
    1: No Alarms generated, but disable boiler on event
    2: Generate LOKA/B Lockout Alarm and disable boiler
    on fault
    3: Generate GENA/B General Alarm but do not disable boiler          on fault
    4: Generate STOP alarm if input ‘a’ in alarm condition
    (input ‘b’ operates as General alarm)

0

0 to 4
