The heating timer-thermostat function is used to program the pellet boiler stove to automatically turn on and off within
a period of one week.
To access programming, hold down button
for around three seconds, “
U T 0 1
” will be shown on the upper display:
by pressing button several times and referring to the table below, the stove can be programmed according to your
needs. Press button to exit the programming phase at any time.
These are the heating timer-thermostat parameters:

Water Characteristics
The characteristics of the water used to fill the system are
very important to prevent the build-up of mineral salts and
the formation of incrustations along the pipes, in the boiler
and in the heat exchangers.
Therefore, please get your plumber’s advice concering:
• Hardness of water circulating in the system, to prevent
problems of incrustation and limescale, especially in
the domestic water heat exchanger (>25° ).
• Installation of a water softener (if water hardness > 25°
).
• Filling the system with treated water (demineralised).
If you have very extensive system, with a large amount of
water, or which require frequent refilling, it is recommended
the installation of water softening system. It ‘should
be noted that the encrustations drastically reduce
performance because of their low thermal conductivity.
