Room Unit
Before the boiler’s start up, an “Auto Set” is necessary so that the boiler
detects the DHW sensor.
To do this, turn the right button to “RESET” then start up the boiler by
pressing on the ON/OFF switch.
From the time that the display shows “SET” the “RESET” button can
be released.

SCHEmATIC DIAgRAm
A Room Unit thermostat controls the heating (radiators or floor heating).
The latter enables a choice between different heating functions and authorises
up to 3 daily programmes for heating and for domestic hot water. The Room
Unit thermostat has the advantage of displaying information on system status.
In this configuration, the boiler continuously adapts its operation to the
outside temperature.
A. - Heating temperature setting guidelines without external sensor
- Maximum heating temperature limit with external sensor
- The thermostat is positioned on , the heating circuit is deactivated
and the boiler is then in summer mode..
B. - Domestic hot water temperature setting.
(Prestige Excellence or as an option with an external domestic
hot water tank).
when connected with a "Room unit", the two knobs (A) and (B)
have no action on the boiler, except for the "RESET" function.
