The water law of the heating circuit is programmed on the NAVISTEM B3000 with a weekly heating
programme.
The AGU 2.550 interfaces built into the boiler are used to control the two three-way regulating valves of
the heating networks.
The boiler operates in variable flow temperature according to the outdoor temperature measured by the
exterior sensor QAC 34, without a low temperature limit.
The production of domestic hot water is controlled by the NAVISTEM B3000 using the QAZ 36 sensor in
the tank.
