3.1 Choose installation location
Installation in the living room
zAttach the thermostat to an interior wall of
the reference room (Fig. 15).
zEnsure sufficient free space around the
thermostat (Fig. 15, pos. 1).
3.2 Assemble wall panel
The wall panel can directly be attached to the
wall or on a junction box.
zRemove the plug of the boiler from the
socket.
zConnect the cable of the thermostat to the
cable clamps "RC" (Fig. 16, pos. 1). The
connection order of the wires is arbitrary.

A reference room is a room (e.g. the
living room) where:
– the temperature can be measured,
which is representative for the
whole house;
– one spends most of its time.
Do not install the thermostat too close
to sources of heat, such as a radiator,
lamp or television. These can
influence the control.
Fig. 16 Connect thermostat cable

Ensure at installation on a junction
box, that possible draught from the
junction box cannot influence the
measurement of the room
temperature. If necessary, fill up the
junction box with insulation material.
NOTE!
Do not connect the wires to the
"EXT"-connection.
