The boiler operates in variable flow temperature according to the outdoor temperature measured by the
exterior sensor QAC 34.
The heating water law is programmed on the NAVISTEM B3100, with or without a low temperature limit
and with a weekly programme.
The heating pump must be able to operate at a constant speed to ensure the minimum flow rate that is
required by the generator.
If the installation is equipped with thermostatic taps on the emitters, the bypass between the outward and
return lines of the network is essential. It is equipped with a differential valve that allows for the free flow of
the heating pump when the thermostatic taps close.
