WORKING MODE: This central heating control device provides you
both the room thermostat function and the weekly clock function.
When in AUTO mode, the central heating will be ON/OFF according
to the programmed times and according to the set comfort temper-
ature (the ON command is identified by the flame icon). When the

the "economy temperature", selectable inside the main menu (16°C
is the default value).
When in OFF mode the heating requested will be switched on when
the room temperature drops under the frost protection value (default
is 5°C); this value can be modified inside the technical menu.
When in PARTY mode the heating request is permanently on ac-
cording the selected comfort temperature that can be modified any
time rotating the encoder and pressing to confirm.
