Congratulations on the purchase of this TH350 thermostat.
For best performance and to enable the best use of this
programmable thermostat's characteristics and functions
please read this manual carefully and keep it available for
future reference.
WARNINGS FOR THE INSTALLER
• Read the warnings contained herein with care as they
furnish important instructions regarding safe use, instal-
lation and maintenance.
• After removing the packaging check the condition of
the unit.
• The system must be installed in compliance with current
safety standards.
• The manufacturer declines all liability for any damage as
a result of improper, incorrect or unreasonable use.
• Should the unit be in need of repair contact only a tech-
nical support centre authorised by the manufacturer.
• Failure to comply with the above instructions may com-
promise the unit's safety.
THERMOPROGRAM TH350
The TH350 programmable thermostat has been designed
to ensure perfect temperatures any time of day, any day
of the week.
The TH350 features a new temperature control system
and new functions.
The TH350 has been designed to guarantee ideal tem-
perature conditions and to adapt itself to all types of sys-
tems having differing thermal inertias (convector heaters,
radiant underfloor heating, electric heaters, etc.).
It is possible to choose between differential control mode
and integral proportional control mode (management of
cycles/hour). The latter allows the programmable ther-
mostat to reduce the time the boiler is in operation as the
room temperature approaches the desired temperature.
This provides a greater reduction in consumption while
at the same time providing the highest levels of comfort.
The TH350 has new features and functions that include:
• a backlit display;
• the possibility to set boiler ignition down to the quar-
ter-hour;
• a new AUTOMATIC ADVANCE function that allows the
TH350 to self-learn the periodicity required to achieve the
desired temperature at any chosen point in time;
• an option to calibrate the measured room temperature;
Use only ALKALINE batteries

• the use of a GSM relay interface which makes it possible
to remotely activate a manual or timer controlled pro-
gramme thus ensuring a welcoming return home.
Wall mounting the installation takes only minutes. The
thermostat can be connected to the heating/cooling
installation simply by means of two wires.
Three alkaline LR03 1.5V penlight AAA batteries are
used to power TH350 for over a year. Once installed
the unit is ready for operation based on its permanent
memory standard programme. Based on actual needs,
the programme can be modified as required by setting
the desired temperatures for different times of the day
and week.
The TH350 can be programmed with great ease, even
before it is installed. The spacious backlit display makes
this easier, because at any time it permits the viewing
of all data and programmes which can subsequently be
changed as required.
Pressing the programming buttons causes the display to
light up for about 15 seconds from the last time any key
was pressed.
The thermal differential is programmable from 0°C to
0.9°C. The TH350 can control both heating and air-condi-
tioning systems, and can be installed as a replacement for
a previous on/off programmable thermostat.
Thermal differential is programmable from
0°C to 0.9°C.
Suitable for systems with differing thermal inertias
(convector heaters, underfloor heating, electric
heaters) ensuring best system use with the lowest
possible consumption.
Proportional/integral adjustment programme
Allows for energy consumption optimisation with
maximum room comfort thus reducing boiler
operating times based on the difference between
the set temperature and the room temperature.
The smaller the difference between these tem-
peratures the shorter the boiler ignition time will
be compared to previously.
AUTOMATIC ADVANCE function
TheTH350 self-adjusts so as to provide the desired
temperature at the pre-selected time.
Boiler ignition and shutdown setting with 15
minute precision
In automatic operating mode the TH350 can
ignite or shut-down the boiler on the half or
quarter of each hour, thus allowing for more pre-
cise management of room comfort programmes
and substantially optimising boiler energy con-
sumption.

Supports
Calibration of temperature measurement
If the TH350is not properly installed (e.g. installed
near a heat source), temperature measurement
may be incorrect or may not correspond to the
actual temperature.
To solve this problem, it is possible to calibrate the
reading to within ±3°C and in so doing optimise
comfort and consumption.
Easy and complete daily/weekly 3-level pro-
gramming
With the TH350, temperatures for any time of any
day of the week can be programmed in a simple
and intuitive manner. Just a few buttons are used
to set the hourly temperature while at the same
time providing constant on-screen monitoring of
programming progress.

1  INSTALLATION
Install the unit in a position which is suitable for correct
room temperature measurement for example on an
internal wall. Avoid installation in niches, behind doors or
curtains, or near heat sources.
The TH350 is designed to be installed within a 3 module
recessed back-box having a depth of 50mm. Proceed as
follows:
• Pull the tab L forwards. The main unit of the thermostat
will follow until it is blocked by two lateral stop tabs (3).
Press the lateral tabs marked by the symbol (fig. 4)
and extract the main unit of the thermostat completely.
• Insert 3 alkaline LR03 penlight AAA 1.5V batteries
within the housing. Make sure the poles face the right
way as shown on the bottom of the housing (fig. 5).

ATTENTION. Inserting the batteries the wrong way round
could damage the unit. Once these steps have been
carried out correctly the symbols shown in figure 6 will
appear on the display.
Choose the support (A, B, C or D) and front facing cover
as a function of the surround to be fitted.
To remove the front cover proceed as indicated in figure 7.
