Additional information

With outdoor reset the boiler will provide the water tem- perature according to the heating curve adjusted by the level of room influence (if enabled).

The boiler will always attempt to run at its highest efficiency in low fire for as long as necessary.

The boiler will shut down when the target temperature is reached followed by a 3 minute post purge by the pump.

The boiler and the pump will start again when the supply water temperature drops 18°F (10°C) below the set point.

When the demand for hot water is sensed by the flow sensor, the boiler will change to DHW mode. When the DHW demand ends, the boiler will return to heating mode.
