Temporary switch-off

In the event of temporary absences (weekends, short breaks, etc.) set the status of the
boiler to OFF .
While the electrical supply and the fuel supply remain active, the boiler is protected by the
systems:
- heating anti-freeze: this function is activated if the temperature measured by the flow
sensor drops below 5°C. A heat request is generated in this phase with the ignition of the
burner at minimum output, which is maintained until the outlet water temperature reaches
35° C;
- domestic hot water anti-freeze (only with water tank with probe): this function is
activated if the temperature measured by the water tank probe drops below 5°C. A heat
request is generated in this phase with the ignition of the burner at minimum output,
which is maintained until the outlet water temperature reaches 55° C.
b
The operation of the ANTI-FREEZE function is indicated by a scrolling message
on the interface display: AF1 (DHW antifreeze in progress) - AF2 (CH antifreeze in
progress), as the case may be.
- circulator anti-locking: the circulator activates every 24 hours of stoppage for 30
seconds.

Switching off for lengthy periods

The long term non use of the boiler causes the following operations to be carried out:
- set the status of the boiler to
- set the system's main switch to "off"
- close the fuel and water taps of the heating and domestic hot water system.
In this case, the anti-freeze and anti-blocking systems are deactivated. Drain the heating
and domestic water system if there is any risk of freezing.
