Installation instructions
It is recommended that the installation be
carried out by a qualified personal.
Location
To assure adequate operation, this thermo-
stat should be installed on an indoor wall,
in a frequently occupied area of the build-
ing. Furthermore, it should be at at least 50
cms. from any outside wall, and at approxi-
mately 1.5 m. above floor level, in an area
with freely circulating air at average tem-
perature. The following locations should be
avoided:
- Behind doors or in corners where freely
circulating air is unavailable.
- Where direct sunlight or radiant heat gen-
erated by other appliances may alter the
control operation.
- On an outside wall.
- Next to or in line with air conditioning dis-
charge grids, stairwells or doors leading
outdoors.
- Where operation can be affected by steam
or water pipes, or hot air chimneys in ad-
jacent areas or any other unheated/
uncooled area behind the thermostat.
- Where operation can be affected by the
supply air of any adjacent unit.
- Near sources of electrical interference,
such as arching relay contacts.
Basic elements
This thermostat comprises three parts:
- Hinged front cover.
- Front panel. This element contains the
operating and control keys, as well as the
printed circuit. Fastened to the base by
means of a plastic tab.
- The base. This box allows fastening the
thermostat to the wall, and contains the
electrical connecting strips.

Thermostat installation
To fasten the thermostat to the wall, open
the front panel and uncover the base of the
thermostat. Proceed as shown in the follow-
ing illustration:
1- Press the plastic tab at the base of the
thermostat, as indicated by arrow A.
2- While pressing A, raise the front panel
as indicated by arrow B.
The fastening holes found at the base co-
incide with the standard electric boxes on
the market.
In the case the connecting cable does not
come from the electric box, the thermostat
must be fastened to the wall with the an-
chors and screws supplied.
Keep in mind that the rectangular hole in
the centre of the base is to house the elec-
tric connecting cable.
