37 Time constant for return temperature limitation

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.

The DHW pump can continue to run after charging to utilize the
remaining heat in the heat exchanger / boiler.

The P2 pump is the charging pump in applications 2 and 2a.

41 DHW charging pump post-run (P4)

Circuit

Set the post-run time of the DHW charging pump in the
secondary circuit. The setting only applies to heating system
types 4, 5, 6 and 6a in section 10.
0:
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).
