Have R 's Technical Assistance Service start-up your boiler for the first time. Once this has been done, the boiler
can be left to function automatically. Under certain circumstances, such as after long periods of disuse, the user may
need to re-start it without involving the Technical Assistance Service. Before doing so, perform the following checks
and operations.
− Check that the fuel cock and heating system wa-
ter cock are shut.
− While the system is still cold, check that the pres-
sure in the heating circuit is over 1 bar but be-
low the maximum limit specified for the boiler.
If water pressure is low, contact
Assistance Service.
− While the system is still cold, check that the pres-
sure in the solar circuit is over 3 bar but below
the maximum limit specified for the boiler. If
water pressure is low, contact
Assistance Service.
− Set the room thermostat to the required tempe-
rature (20°C).
− Switch the electricity supply ON at the system's
main switch and at the control panel. Make sure
that the green power indicator lights.
− The boiler switches on and the display shows the
software version of the main control board.
