C. OPERATING DESCRIPTION
The boiler operates at the flow temperature required to produce the domestic hot water.
The heating pump must be able to operate at a constant speed to ensure the minimum flow rate that is
required by the generator.
The domestic hot water production system has its own regulator.
A sensor QAZ 36, positioned inside the storage tank and connected to the generator, informs the boiler of
the need for domestic hot water.
