Boiler pump alarms

The boiler pump status, if connected will influence only the start procedures of this macro.

If you need pump alarms to stop the boiler, you have to add an extra pump macro and connect the pump alarm output “CommAlarm” to the input “PumpAlarm” of this macro.

The default value of the pump status input is 999, which means that the end-switch is not connected.

You can connect the digital input of the pump status input without receiving a mismatch alarm.

The alarm reset depends on the parameter SYS-06, which will reset the alarm manually by default.

In case of manual reset, the alarm must be reset via the input “Reset” by pushing the reset button.

When a pump alarm occurs the boiler will switch off but the pump output will be stay on to avoid repeated on- off switching in case of automatic reset. The alarm is sent to the heating control strategy, in order to enable the next boiler.
