11.3- Operation Functions
11.3.1- Standby (OFF Mode):
The mode where boiler can be set to standby mode. In this mode, no
requests for heating water and domestic water can be made. To activate the OFF mode, it is necessary to

mode is activated is listed here below.
Once the boiler is powered for the first time or after the electricity has been switched off and on,
After the reset operation following the overheating fault (E03),
After elimination of high water pressure (F40) or low water pressure (F37) error,
CAUTION: Do not press 'RESET' while AP mode is active.
11.3.3- Winter mode-Radiator Heating:
If the boiler in the standby position is set to the winter position,
it will heat the water in the heating circuit until the domestic water is needed. In the winter mode, both the
