INSTALLATION AND CONNECTIONS
SAFETY REQUIREMENTS
: before installing this programmable thermostat, make sure
that the supply voltage to the equipment load (heater, pump, etc.) is not connected
and that the load is within the ratings shown inside the thermostat.
POSITIONING
: install the programmable thermostat away from sources of heat
(heaters, direct sunlight, kitchens) and from doors/windows, at a height of about
1.5 m above the floor.
INSTALLATION
- Release the small catch with the aid of a screwdriver and remove cover (fig.
2
)
- Fix the base to the wall
- Connect the load to the terminals following the wiring diagram (cable Ø 2.5 mm
2
) (fig.
3
)
- Replace cover and re-set the catch

SUMMER/WINTER SETTING
The thermostat can be used for “summer” or “winter” operation, depending on whether it
is connected to an air-conditioner or to a heater. Press the button (D) to change from
SUMMER to WINTER setting, or vice versa. Choosing the SUMMER setting, the GREEN
LED (B) blinking 3 times; choosing the WINTER setting, the RED LED (A) blinking 3 times.
DAY/NIGHT SETTING
Move the selector (E) to change from DAY to NIGHT setting and vice versa. Under NIGHT
setting, the temperature is automatically setback by 3°C from the DAY temperature as set
by the graduated knob (C).
THERMOSTAT START-UP/SWITCHING OFF
Turn the graduated knob (C) to the right, to switch-ON the thermostat and to set the
temperature; Turn the graduated knob (C) fully to the left (until to heard a click) to switch
the thermostat OFF.
SETTING THE TEMPERATURES
After having set either SUMMER or WINTER setting, chose DAY by the selector (E) and
turn the graduated knob (C) to the desired temperature.
Note
: following the instructions below (fig.
4
) it is possible to mechanically block the
graduated knob to restrict the set temperature within specific limits.
- Release the small catch with the aid of a screwdriver and remove the cover (fig.
2
).
- With the knob set to 30°C, remove the tappets 1, 2 and 3 (fig.
4
/a).
- Rotate the knob to reveal a series of holes, and insert 2 tappets appropriate to the required
upper and lower limits. Each hole corresponds to 1°C (Fig.
4
/b).
- Turn the graduated knob such that the third tappet can be inserted in the position shown,
ensuring it is between tappets 1 and 2 (fig.
4
/c).
- Refit the cover and re-set the catch.
FROST PROTECTION OPERATION
With the thermostat turned OFF (under WINTER setting) frost protection is ON.
Should the heater turn on, the RED LED will blink.
OPERATIONAL NOTES
- When the RED LED blinking, the heater is ON.
- When the GREEN LED blinking, the air conditioning is ON.
BATTERY
Power Supply: 2 ALKALINE Batteries 1.5 V AAA. When the batteries are
low, the RED and GREEN LED will blink contemporaneously; for changing
the batteries, see fig.
5
. After replacing the batteries, the thermostat re-starts
in the heating mode (the RED led blinking).
Please dispose of the worn out batteries according to prevailing regulations
.
