Operation of the integral circulation pump as heating circuit pump for heating circuit 1
The pump speed and consequently the pump rate are
controlled subject to the outside temperature and the
switching times for heating mode or reduced mode.
The minimum and maximum speeds for heating mode
can be matched to the existing heating system at the
control unit.
