Make sure there are no pipes or electric wires in the
wall which could be damaged while mounting the
appliance.
The appliance is equipped with a sensor which can
detect an open window, if present above the radia-
tor or within the room. For a proper operation, it
is strongly recommended to comply to the instal-
lation directions reported in Ch. 4.3.2 before wall
mounting.
3.1 WALL MOUNTING

mounting pack are suitable for the type of wall
on which you are mounting the appliance. If in
doubt, contact a qualified professional or your lo-
cal dealer.
During installation, make sure the power cable is
disconnected from the power line.
To mount on the wall, see from page 193 of these
instructions.

Case 2: installation
with Pilot Wire
The appliance requires a 230 V ~ 50 Hz power
supply. Make sure the power line is appropriate
for the data given in table 1.
Make sure the fixed power line is fitted with a
disconnecting switch allowing the appliance to
be disconnected completely from the household
mains, included the Pilot Wire, when present, in
accordance with the wiring rules.
If the appliance is installed in a bathroom, the
power line must be fitted with a 30 mA RCD (high
sensitivity residual current protection device).
The power supply line and Pilot Wire control unit
must be protected by the same RCD.
Permanently connected appliances must be con-
nected using a connector block placed within a
proper junction box.
When installing the appliance in damp rooms
(kitchen, bathroom), the point of connection with
the household mains must be at least 25 cm from
the floor.
Respect the wiring diagram in figure 8 scrupu-
lously.
If the Pilot Wire is not connected to the
programming unit, it must be terminated and
insulated. Under no circumstances should the
Pilot Wire be connected to the earth.
Make sure the power cable cannot in any way
come into contact with the surface of the
appliance (Fig. 7).
