The THERMOPROGRAM is extre-

it is installed; a spacious display
facilitates this operation, since you
can “see” and change all the infor-
mation and program settings at
any time.
The temperature threshold can be
set at values between ± 0.1 °C and
±0.9 °C.
The THERMOPROGRAM can
generally control both heating and
cooling plants and it can replace
any previous on/off thermostat.
THERMOPROGRAM
TH400
The TH400 THERMOPROGRAM
programmable thermostat is desi-
gned to ensure ideal temperature
conditions at all hours of the day
and every day of the week.
It takes only minutes to install,
because it is connected to the hea-
ting/cooling plant simply by means
of two wires.
Three LR03 type AAA 1.5V alkaline
batteries are used to power the
THERMOPROGRAM for over a year.
Once it has been installed, it is
immediately ready to operate with
its permanently-memorized stan-
dard program.
To suit individual needs, the pro-
gram can be adjusted at will, set-
ting the required temperatures for
the various times of the day and
week.

1 - INSTALLATION
Install the thermostat in a position
where it can detect the average
room temperature, figure 3, avoi-
ding placing the thermostat inside
recesses, behind doors or cur-
tains, or near radiators, figure 4.
•Remove the bracket from the
thermostat body, figure 5, and fix it
directly to the wall, figure 6, or on
a flush-mounted junction box,
figure 7 or figure 8, making sure
that it is the right side up.
Fig. 8
•Open the front panel on the ther-
mostat and slide out the battery
cover, figure 9.
•Make the electric connections to
the terminal board situated on the
back of the thermostat, figure 10,
as illustrated in the diagrams in

are set as follows:
T1 16 °C
T2 18 °C
T3 20 °C

comfortable temperature for lon-
ger when visitors arrive, or to eco-
nomize while away for lengthy
periods).
Once you have set the required
time, the counter begins a count-
down, at the end of which the ther-
mostat switches from MANUAL to
AUTOMATIC mode, running the
system according to the pre-set
program.
Programming in hours
5.1 - Make sure that you are in
MANUAL mode.

If you temporarily want a different
temperature without interfering
with the program settings, you can
switch to MANUAL mode by pres-
sing the button, figure 26.
The program graph on the display
is canceled and the temperature
reading refers to the previously-set
temperature, which can be varied
at will by means of the or
button (the thermostat is despat-
ched with a default temperature
value of 20 °C), figure 27.
After about 5 s since the last ope-
ration, the display returns to indi-
cating the room temperature.
You can check the temperature
setting at any time by pressing the
button twice.
In MANUAL mode, you can select
any temperature between 2 °C and
35 °C and this will be kept constant
