37 Time constant for return temperature limitation
Circuit Setting range Factory setting
I OFF / 1 ... 50 25
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 dierence
between the acceptable and the actual return
temperature.
The dierence is integrated to adjust the desired
ow temperature.
OFF: The desired ow temperature will not be
adjusted any further.
1: The desired ow temperature will be
adjusted quickly.
50: The desired ow temperature will be
adjusted slowly.
40 DHW charging pump post-run (P2)
Circuit Setting range Factory setting
I 0 ... 9 min. 1 min.
The DHW charging pump can continue to run after charging to
utilize the remaining heat in the heat exchanger / boiler.
0: The pump stops immediately after
charging.
1 ... 9: The time the pump runs after the charging
has ended.
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.
44 Max. DHW charging time
Circuit Setting range Factory setting
I 0 ... 250 min. 0 min.
When the set max. DHW charging time expires, the charging is
deactivated.
0: No max. DHW charging time.
1 ... 250:
