Supervision of faults

The main pump (main twin pump) can be monitored with an overload input each and/or
a flow switch each (... Extra configuration > Boiler sequence manager > Inputs).
The parameters for the pump or twin pump fault inputs are fixed and cannot be
changed.
The fault status signal delay for the flow switch is 60 seconds.
The setting parameters for the main twin pump can be found on menu ... Settings > Boiler
sequence manager > Twin pump. For more detailed information about the functionality of
the twin pump, refer to chapter 5 "General functions, fundamentals".
