Mechanical Construction

In the thermostat’s front panel shown in Fig. 1 are indicated the following:

- mode selector (1);

- red led indicator (2);

- set-point knob (3).
The mode selector (1) has three different positions:

PROGRAM: Night reduction enabled
COMFORT: Comfort position
OFF: Off position

The red led indicator (2) flashes when batteries are exhausted and gives an information about the
actual regulation when the mode selector (1) is moved. Through the set-point knob (3) the user can
set the temperature around which the regulation will take place.

To access to the internal part of the thermostat, is necessary to open the plastic case, by removing
the frontal panel. To remove it, remove first the knob using a small screwdriver, place it in the slot
(11) visible in the Fig. 3 and Fig. 4 and apply a slight pressure. Afterwards use the screwdriver to
drive the plastic teeth (4) shown in Fig. 3.

Apply a light pressure with a screwdriver between the tooth and the hole in the plastics, but do not
push directly on the tooth in order not to break it.

The Fig. 2 represents the plastic box section and it shows how to handle the screwdriver correctly.
