6 The settings in detail 28.01.2015
If, during charging, the temperature at sensor B36 (DHW charging temp (8836))
exceeds the charging setpoint by the current Switching diff off min DHW
(2461)/Switching diff off max DHW (2462), the burner is switched off. It is switched on
again as soon as the temperature at sensor B36 drops by the parameterized Switching
diff on DHW (2460) below the charging temperature setpoint. The setting range for the
switch-on differential starts at 0 °C.
The output request to the burner is controlled between the parameterized Required
speed LF min (9525) and the maximum output for Fan speed full charging max (2442).
If, during the time full charging is active, the enable criterion for full charging does not
apply anymore, the DHW request is ended according to the criteria for recharging.
