Possible change
4B:1 External demand.
4B:2 External blocking.
51:1 System with low loss header:
When there is heat demand, the
boiler circuit pump will only be
started if the burner is running.
Circulation pump is switched off
when run-on time expires.
51:2 System with heating water buffer
DHW tank:
When there is a heat demand, the
internal circulation pump will only
be started when the burner is
operational.
