Thermal control valve
T
flow
< T
fix
The thermal control valve keeps the flow line
of the mixing valve completely open as
long as the water from the flow line to the
consumer is colder than the flow temperature
set of the thermal control valve.
T
flow
≈ T
fix
As soon as the water in the flow line has
reached the temperature set (+/- 5 K) of the
thermal control valve, the valve starts closing
the flow line of the storage tank / modular
distribution manifold and opens the return
line to the same extent (coming from the
consumers). The cold water from the return
line is mixed in the control valve with the hot
water from the flow line. Depending on the
temperature, the thermal control valve opens
or closes the flow line of the storage tank /
modular distribution manifold.
T
flow
> T
fix
With rising temperature in the flow line or
rising temperature from the consumer return
line, the thermal control valve shuts off the
inlet of even hotter water. The temperature
of the flow to the HeatBloC / consumer
remains approximately constant during
operation.
