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 two others will be managed by the RVS 63 integrated into an outside case at
the boiler.
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.
