Fitting the Programmable Room
Thermostat
The ideal position to locate the
Programmable Room Thermostat is
about 1.5m above floor level, in a
location where the thermostat is
accessible, reasonably lit and free
from extremes of temperature and
draughts. Do not position the
thermostat near sources of heat,
such as radiators, lights, TV, direct
sunlight or on an outside wall.
Installation
1. Remove the front cover
using a flat screwdriver in the two holes at the top of the programmer and separate from back plate.
2. Fix the back plate directly on the wall using suitable wall plugs and screws.
3. Unscrew the cover that is protecting the live terminals. Lift the cover to expose the wiring block, taking care to
retain the screw.
4. Complete the connections in accordance with the wiring diagram (page 6, Section 15).
5. Replace the thermostat onto the back plate, securing the bottom of the thermostat first and clicking the
thermostat into place.
6. Insert the 2 x AA batteries provided in the battery compartment on the front of the thermostat, underneath the
fascia. The Programmable Room Thermostat is now installed and will automatically start to control the room
temperature according to the factory pre-set programme as shown in the User Instructions. The display shows
the correct time and date which is automatically set together with the actual room temperature.
