Circuit
(I) / (II)
Controls how fast the actual return temperature adapts to the
desired return temperature limitation.
Adjust the time constant for the return limitation.
The setting will eliminate the difference
between the acceptable and the actual return
temperature.
The difference is integrated to adjust the desired
flow temperature.

1 ... 9: The time the pump runs after the charging
When the DHW charging pump runs after the charging of
the DHW tank has stopped, the heat in the exchanger can be
utilized to a better extent.
The post-run of the DHW charging pump (line 41) should not be
set to a shorter time than that of the DHW pump (line 40).
