Diagram 1 (boiler sensor)
Diagram 1 allows operating a heating system where there is also a boiler for DHW production. The boiler can be connected to other
heat production units, such as solar panels.
With this diagram, the stove operates to bring the boiler to the set temperature; when the set water temperature is reached, the three-
way valve changes position and the thermo-stove begins to exchange heat in the heating system. From now on, the boiler is operated
by an external thermostat or by the internal H2O set (as in diagram 0). The thermo-stove reheats the boiler once the boiler water
temperature has fallen below the set-point value or when the flow switch (if connected) detects DHW being used.
If the thermo-stove is in ECO STOP mode or in WATER STAND-BY mode, a request by the Boiler of flow meter is added to diagram
0 standard start-up conditions.
