3. THERMOSTAT POSITIONING

Proper positioning of the thermostat is very important to
!
ensure accurate room temperature measurement.
Observe the following general rules for best results.
1. The thermostat should be fitted on an inside wall of the room where the
heating is installed, approx. 1.5 m (5 ft.) above the floor.
2. Avoid areas which have unusual heating or cooling conditions, such as
direct sunlight, near a fireplace, stove, door, window or stairway.
3. Be aware of furnishings which may block airflow or alter the temperature
such as: sofas, chairs, bookcases, track lighting, lamps, stereo equipment,
television sets etc.
4. Note that hot water pipes in the wall, a stove, refrigerator or fireplace on
the other side of the wall may also affect the operation and accuracy of
your thermostat.
5. Positioning the thermostat in a damp area will cause corrosion and shorten
the life of the thermostat.
6. Do not install the unit where air circulation is poor (e.g. in a corner, alcove,
or behind a door).
7. All construction work and painting must be completed before installation.
N.B. This thermostat does not require levelling.
To avoid electrical shock and to prevent damage
