If the heating system is equipped with a DHW tank, DHW heating must be
activated. The factory setting is "ON".
If no DHW heating is installed, it should be disabled to avoid the DHW SENSR
ERR error message.
The controls starts the burner if necessary in order to heat the DWH. The DHW
tank charging pump runs. Once the burner has been switched off, the controls
uses the residual heat in the boiler to heat the DHW.
Once the set DHW temperature is reached, the DHW tank charging pump is
switched off. Normal heating mode is resumed at the end of the DHW heating
cycle.
A recirculation pump (if installed) may be controlled if the DHW heating is
