The display shows OFF, the clock and the room temperature. The antifreeze function is active.
In this mode the thermostat preserves the system by activating the boiler only when the room
temperature drops below a minimum value (factory set at +6°C).
ACTIVE MODES: AUTOMATIC [

Press
in succession to switch to [
.AUTO] mode, [MAN] mode and to return to [OFF] mode.
.AUTO = Temperature Regulation according to time Program
MAN = Operation with Manual Temperature set.
Pressing the <SET> key in these two operating modes allows alternate displaying of the clock or of the
active set temperature (in the top right of the display).

Time programming
Before proceeding with programming, make sure that the clock settings are set correctly.
Otherwise, go to the user menu to update the data (see USER MENU chapter).
DAY model programming
The 24 keys correspond to the 24 hours of the day and are only active in [AUTO] mode.
Press the key corresponding to the desired time to activate the TC (its segment will be on) or TR (its
segment will be off).
For each hour it is possible to program the single ½. Press the key several times to obtain the on and
off sequence of the corresponding segment, as indicated below.

Run the new day program and repeat until the weekly programming is complete. Once finished, press
the program and to return to the AUTO mode.
Copy function
To facilitate weekly programming, it is possible to copy the daily settings entered to the next day. Once the day
programming is set press <SET>. The programming will be copied to the next day (the new day flashes). With each

additional touch of the <SET> key, the programming will be copied to the next day.
At the end press
to exit the programming and to validate the choices.
EACH CHANGE TO THE ACTIVE DAY PROGRAMMING CHANGES THE PREVIOUS SETTINGS. THE CHANGE IS
IMMEDIATELY ACQUIRED AND ACTIVATED WITHOUT THE NEED FOR ACCESS TO PROGRAMMING FUNCTIONS OR
FURTHER CONFIRMATION.
Temporary forcing of the set temperature
During operation in [AUTO] mode it is possible to TEMPORARILY change the value of the desired temperature active
at that time (either TC or TR) without entering programming mode.
This change does not alter the pre-set values of TC or TR and is only active until the next change of state (TC/TR or
vice-versa) provided by the program.
Pressing the <+/-> keys changes the value of the active temperature that is flashing in the upper right. The setting
is acquired by pressing the <SET> key or at the end of the flashing.
N.B.: IF THERE ARE NO CHANGES OF STATUS IN THE PROGRAM, FROM TC TO TR OR FROM TR TO TC, AFTER FORCING,
THIS FUNCTION WILL REMAIN ACTIVE AND WILL BE EQUIVALENT TO USING THE DEVICE IN [MAN] MODE.

The thermostat regulates the room temperature exclusively according to the manual temperature setting.
Press <SET> to display the set temperature.
Press the <+/-> keys to change the desired temperature (between 5 and 35°C). The value is displayed in the upper
right flashing. The setting is acquired by pressing the <SET> key or at the end of the flashing.

WINTER SEASON MODE (
) (Factory Setting)
The Comfort Temperature is greater than the Reduced Temperature (TC > TR)
Tamb = room temperature
Tset = set temperature
When Tamb < Tset, the heating is activated, flame symbol active
When Tamb = Tset, the heating is deactivated, the flame symbol is no longer present on the display.
The next re-ignition will occur when the Tamb < Tset – hysteresis.
To switch from Winter (Heating) season mode to Summer (Conditioning) season mode and vice-versa refer to the
next USER MENU chapter.
SUMMER SEASON MODE (

The Comfort Temperature is lower than the Reduced Temperature (TC < TR)
Tamb = room temperature
Tset = set temperature
When Tamb > Tset, the cooling is activated, active fan symbol

Displaying of word [rSt]. Press and hold the <+> and <-> keys simultaneously for a few seconds.
Evidence of the reset to the factory settings is given by the shutdown of the display and the progressive display
of three horizontal segments with the subsequent thermostat restart.
TO NOT PERFORM A RESET TO THE FACTORY PARAMETERS, PRESS THE <SET> KEY TO CONFIRM THE OPERATION
AND EXIT THE INSTALLER MENU.
TYPES OF REGULATION
Hysteresis On/Off regulation
This is the traditional ON/off operation: in winter the system is activated continuously until the desired room
temperature is reached.
At this point the system will remain off until the room temperature drops below the desired temperature minus
another factor called hysteresis. In summer mode the operation is reversed.
TPI regulation
The TPI is a type of regulation that ensures activation of the system for the minimum time necessary, but
sufficient to maintain the room at the selected temperature.
A thermostat with TPI continuously measures the ambient temperature in which it is placed and performs a series
of calculations to establish the duration of the ignition of the system to reach and maintain the set temperature,
thus increasing energy efficiency.
The system will turn on for increasingly shorter periods as it approaches the correct temperature. When the
setpoint temperature value is reached in the room, the system is switched on for short periods in order to
maintain this temperature.
WARNINGS FOR CORRECT DISPOSAL OF THE PRODUCT
At the end of its useful life, the product must not be disposed of together with municipal waste.
It can be delivered to the appropriate separate collection centres set up by the local authorities, or to the retailers
that provide this service.
Disposing of an electrical or electronic appliance separately avoids possible negative consequences for the
environment and health deriving from its inadequate disposal and allows recovering of the materials of which it
is composed in order to obtain the significant saving of energy and resources.
To highlight the obligation to dispose of electrical and electronic equipment separately, the product bears the
crossed-out mobile waste container mark.
