Brief description:
The CH pump (11) and the DHW pump (12) can start their operation only after
the boiler exceeds the
CH pump start temp.
(by default 40
°
C). The thermostatic valve (28) closes
at the initial stages of heating, when the water getting into the boiler is cold. This causes the
boiler water to flow in a short cycle: boiler (1)
–
throttle valve (29) - thermostatic valve (28)
–
pump (11). The thermostatic valve (28) opens after the temperature returning to the boiler
increases, directing the boiler water to the central heating system. When the temperature
measured by sensor (8) drops below the preset DHW temperature, the DHW pump (12) is
enabled. The DHW pump (12) will be disabled after the DHW tank (15) is filled, i.e. when the
temperature on sensor (8) is equal to the preset DHW temperature.
