▶ Wait until the maximum temperature has been reached.
▶ Open all DHW taps, from the nearest to the one furthest away, and draw off DHW

minutes.
▶ Reset the DHW thermostat, DHW recirculation pump, and heating control unit to
standard operation.
6 Energy saving tips
Heating economically
The boiler is designed to provide a high level of comfort while keeping gas
consumption and the resulting environmental impact as low as possible. The gas
supply to the burner is controlled according to the heat demand. The boiler
continues to operate on low fire if the demand for heat drops. The technical term for
this process is modulating control, and it reduces temperature fluctuations and
provides even distribution of heat throughout the home. This means that the boiler
may stay on for relatively long periods but will use less gas than an appliance that
continually cycles on and off.
Inspection/Maintenance
To ensure that gas consumption and environmental impact (pollution, etc.) remain
as low as possible over an extended period of time, we recommend that you sign an
inspection/maintenance contract with a trained and certified heating contractor
covering scheduled annual service and maintenance.
To cancel the thermal disinfection:
▶ Switch the appliance OFF and ON again.
The appliance starts up again and the current supply temperature
is displayed.
