THERMOPROGRAM
TH125
The TH125 THERMOPROGRAM program-
mable thermostat is designed to ensure ideal
temperature conditions at all hours of the
day.
It takes only minutes to install, because it is
connected to the heating/cooling plant sim-
ply by means of two wires.
Three LR03 1.5 V penlight AAA alkaline bat-
teries are used to power THERMOPRO-
GRAM for over one year.
The termostat is extremely easy to program
by means of cursors; a spacious display
enables you to see the time, room tempera-
ture and all the settings.
The temperature threshold can be set at ±0.1
°C or ±0.9 °C.
The THERMOPROGRAM can generally con-
trol both heating and cooling plants and it
can replace any previous on/off thermostat.
Congratulations on your purchase of the
TH125 thermostat.
To get the most out of your thermostat,
exploiting its features and functions to the
full, we suggest you read this manual care-
fully and keep it handy for future reference.

1 - LOCATION
Install the unit on an internal wall (fig. 2) in
a position which is suitable for correct mea-
surement of the room temperature, avoiding
installation in niches, behind doors or cur-
tains, or near heat sources.
2 - INSTALLATION
Open the unit by pressing button P (fig. 3)
while at the same time pulling in the direc-
tion of the arrows.
Remove the terminal covers(fig. 4). To
fasten the base to a rectangular recessed
box (fig. 5) use the 2 screws provided.
To install the base in a round box (fig. 6) use
the provided spacer.
To fix the base to the wall (fig. 7) use the
spacer and the two screws with inserts, all
provided.
WARNING. For the unit to work properly, we
recommend you install it on a flat surface,
being careful not to overtighten screws.
WIRING
Wiring will depend on the type of equipment
controlled by the thermostat: refer, therefo-
re, to the diagram in fig. 8 or fig. 9. Refit the
terminal cover.

of the housing (fig. 10).
WARNING. Inserting the batteries the
wrong way can damage the unit.
If the messages on the display do not
appear within 30 seconds, press the reset
button R (fig. 54).
Close the unit, making sure the fasteners fit in
the relevant slots (fig. 11). Once the batteries
have been inserted, the display comes on,
featuring the indications illustrated in fig. 12.
The unit is now set to operate in automatic
mode and with the heating program ( ).
The room temperature reading and battery
status indicator now appear.
WARNING. Any time the unit cover is ope-
ned, when settings are complete, it is
necessary to close it correctly to avoid
wasteful battery consumption (fig. 60).
4 - THERMAL THRESHOLD
The temperature differential can be set from
±0.1 °C to ±0.9 °C.
THERMOPROGRAM is supplied factory set
for operation with a temperature differential
of ±0.2 °C.
This threshold, which establishes how soon
the thermostat reacts to temperature chan-
ges, is intended for systems with a high
thermal inertia, such as systems with cast-
iron radiators.
If the features of the system require modifi-
cation of this value, proceed as follows:
4.1 - Press the button twice (fig. 13).
The message d 0.2 °C appears on the
display for about 10 s.
4.2 - Press the button (back) or
(forward) (fig. 14) until the desired value is
reached.

7 - AUTOMATIC PROGRAM
When the machine is started, it sets up in
AUTOMATIC operating mode.
If the unit is in MANUAL operating mode,
press button (fig. 21) to switch over to
AUTOMATIC. Place cursors 0÷23 (fig. 22)
on the temperature desired for each hour of
the day. Whenever a cursor is moved, the
display gives the temperature set by that
cursor and its position (fig. 23).
You can change programming at any time by
simply moving the cursors to the desired
position.
WARNING. Temperature display is possi-
ble only when the cover is open.
Therefore, if you will not be needing to use
the cursors, close the cover to avoid
wasteful battery use.
