There are three possible selections to activate the Error Relay (alarm) contact:
• On Lockout, Blocking and Warning : the error relay is activated at a non-volatile lock-out (e.g. CH Flow NTC defect), at a
blocking error (self-resetting errors) (e.g. Gas-pressure switch not closed ), or at a warning (e.g. low water pressure warning).
• On Lock-out and blocking : the error relay is activated at a non-volatile lock-out or a blocking error.
• On Lockout : the error relay is activated at a non-volatile lock-out only.
The selection depends on the alarm feedback requirement from the customer.
