Circuit Setting range Factory setting
I OFF / 1 ... 50 20
The setting will eliminate the dierence between the desired
DHW charging temperature (S2) and the DHW temperature (S3)
by integrating the dierence and adjusting the desired S2 ow
temperature.
OFF: The desired DHW charging temperature will
not be adjusted any further.
1: The desired DHW charging temperature will
be adjusted quickly.
50: The desired DHW charging temperature will
be adjusted slowly.
By setting a value (1 … 50) in line 67, the S2 temperature is
increased gradually to ensure a correct DHW temperature (S3).
When looking in the menu B, the desired charging temperature
(at S2) will be higher than the value for the desired charging
temperature, set in menu C (yellow side). This can indicate that
the heat exchanger is not transferring the heat in an optimal way
(limescale).
