IMPORTANT: for the assembly procedure of the thermostat with the chosen residential plate,
follow instructions contained in the specific compatibility sheet contained in the package.

Read this manual carefully before using the product as it provides important guidelines regarding safety, installation and use.
The manual must be preserved with care for future reference.
The installation and electrical connection of the programmable thermostat must be implemented by qualifiedonly a
electrician and in conformity with current laws and regulations.
The thermostat is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or by
those with a lack of experience and knowledge of the instructions, unless they are supervised or have received the necessary
instructions concerning use of the device by a person responsible for their safety.
Children should be supervised to ensure that they do not play with the device.
If (+23°F or + 99.9 °F) room temperature flashes on the display, the measured temperature is beyond the scale.-5 °C or +37.7 °C
If flashes on the display, it indicates faulty probe: any temperature control activity is suspended."Err"
Use 2 stilo 1.5V batteries type AA (LR6). Batteries not included.alkaline
N.B.: the product has been tested and its characteristics are guaranteed when alkaline DURACELL or ENERGIZER batteries are used.
If necessary, gently clean the thermostat and the display with a soft, dry cloth.

PRESENTATION
Dear Customer, thank you for choosing our product.
The thermostat, suitable for all heating and/or cooling system, is fitted with a large and clear backlit display to keep all its functions under
control in real time. The fundamental feature is its easy to use menu navigation, which makes it extremely user-friendly despite its
comprehensive range of functions. The thermostat is factory-set to adjust temperature in a Differential ON/OFF manner and hysteresis
can be set from 0.2°C to 1.2°C to adapt to the thermal inertia of your specific installation. Alternatively, modulating Proportional operation
may be selected with settable duration cycles (from 7 to 20 minutes): this system ensures the desired temperature is maintained more
stable, increasing user comfort and is particularly suitable for installations with high thermal inertia such as, for instance, for underfloor
radiant panels. The set temperature scale is in degrees Centigrade (Celsius) with the option to calibrate room temperature measurement
setting a correction value (from -3 to +3 °C). The thermostat can be connected to a separate remote controllable temperature probe
(optional) which may then be set according to one's installation needs: remote, floor, external.
Special attention was devoted to energy saving: pausing for household cleaning, optional Set temperature (MAX/MIN) lock, adjustable
anti-freeze temperature value, control through an external contact (e.g. optional telephone programmer), are conducive to avoiding
wasting energy with consequent savings. See the following pages for a description of these as well as of other features.

Attention: battery life may be more than 2 years.
However, it is recommended to replace them at least every 24 months to avoid
them running out when you are away (e.g. Christmas holidays, etc.)
Dispose of flat
batteries in
appropriate containers
and as required by the
environmental
protection regulations.

Convenient programming
Attention!
All setting operations may be performed before
inserting the thermostat module to the
recessed base; this means setting may be
carried out while comfortably seated.
The flashing indication with fixed winter orON
summer symbol indicates that the thermostat
is detached from the recessed base.
If programming of the thermostat module takes place before fixing
to the recessed base, upon completing installation the ON
indication (off or flashing) on the display might not correspond to
the actual relay status.
Within 1 minute at the most the insertion of the thermostat module
to the recessed base, the relay activates with the indication (offON
or flashing) displayed.

Important: if the display shows the message , itNO RELAY
indicates that the thermostat module has not been correctly
inserted all the way into the recessed relay base.

5.6 - SIGNALLING BATTERIES LOW OR DOWN
When the symbol blinks, this indicates that the batteries are running out and
as from this moment there are 15 days to replace them.
All thermoregulation is suspended and all settings are saved to be restored when
the new batteries are inserted.
Note: the backlight of the display is automatically deactivated.
If the discharged batteries are not replaced within this time the display will

11.3 - TYPE TEMPERATURE ADJUSTMENT METHODS
The thermostat is factory set to work in modeTHERMAL DIFFERENTIAL
ON/OFF with a preset thermal differential value (Hysteresis) of 0,3 °C.
Note: adjustable from 0,2 °C to 1,2 °C (from 0,3 °F to 2,1 °F).
The hysteresis value must be set according to the system's thermal
inertia; a low value is recommended for systems with radiators made of
e.g. cast iron and a high value for systems with fan coils.
As opposed to the thermal differential, the temperature can be adjusted
MODULATING PROPORTIONALLY (PROP) setting cycles from 7 to 20
minutes (default 10 minutes).
This system maintains the desired temperature more stable, whilst
increasing the user's comfort sensation and saving on energy
consumption.
A long cycle is recommended for systems with high thermal inertia (cast
iron radiators, floor systems) and a short cycle for systems with low
thermal inertia (fan coils).
