Configuration parameter [Fresh water module] 2 pumps function block
The circulation pump is put into operation if the current
[Buffer top fresh water] temperature exceeds the
[Enable circulation] temperature.
Explanation of [Stop diff.]
Optional: only for circulation pump
This defines the difference between the hot water
return temperature [Primary return] and the set hot
water temperature [Target temp.]. The circulation stops
if this difference is fallen short of. Only when the set
difference is exceeded by the additional 2 °C can the
circulation restart.
Example:
[Stop diff.] = 7 °C
[Target temp.] = 50 °C
=> the circulation is stopped if the return temperature
rises [Primary return] above 43 °C (=50-7 °C). The
circulation can restart if the return temperature falls
below 41 °C (=50-7-2 °C).
