Installation instructions
Position
To operate correctly, the thermostat
must be positioned on an indoor par-
tition wall in a part of the building that
is regularly occupied. In addition, it
must be placed at least 50 cm from
any external wall, at a height of
roughly 1.5 m, in a place where the
temperature represents an average
for the building and where the air cir-
culation is unobstructed.
Avoid the following locations:
- Behind doors or in corners where air
does not circulate freely.
- Places where direct lighting or radia-
tor heating installations may affect
the control system.
- On an external wall.
- Next to or facing air-conditioning
discharge grilles, stair wells or exter-
nal doors.
- Places where the presence of water
or steam piping, hot air ducts or an
unoccupied room behind the ther-
mostat may affect its operation
- Near to a unit’s air discharge grille.
- Near to sources of electrical interfer-
ence, such as contact relays.
Removing the thermostat
from its base
1) Place a flat screwdriver blade in
the the slot in the middle of the
unit’s bottom edge. Pull up the
blade gently until the lid comes off
the base.
2) Pull the bottom part of the thermo-
stat towards you and rotate it.
3) Lift up the thermostat to remove it
from the base
4) Connect the system’s wires to the
thermostat, referring to the dia-
gram below. The wiring can then
be inserted in the wall cavity or a
junction box. The access hole
must be made water-tight to pre-
vent air currents inside the wall
affecting the thermostat’s mea-
surements.
5) You need terminal (C) of the 24V
transformer common.
