THERMOPROGRAM
TH125
The TH125 THERMOPROGRAM programmable
thermostat has been designed to guarantee ideal
temperature conditions at all times during the day.
Installation takes only minutes. The thermostat can
be connected to the heating/cooling installation
simply by means of two wires.
Three alkaline LR03 1.5 V penlight AAA batteries
are used to power THERMOPROGRAM for over a
year.
It can be programmed easily using the sliders; the
large display shows the time and ambient temper-
ature together with all programmed data. The ther-
mal differential is adjustable from 0.1°C to 0.9°C
The THERMOPROGRAM can control both heating
and air-conditioning systems, and can be installed
as a replacement for a previous on/off programma-
ble thermostat.
DISPOSAL
Do not litter the environment with packaging mate-
rials: make sure it is disposed of according to the
regulations in force in the country where the prod-
uct is to be used.
When the equipment reaches the end of its life
cycle, avoid discarding it within the environment.
The equipment must be disposed of in compliance
with current regulations, recycling its component
parts wherever possible.
Components that qualify as recyclable waste fea-
ture the relevant symbol and material acronym.

tion which is suitable for correct room temperature
measurement. Avoid installation in niches, behind
doors or curtains, or near heat sources.
2 - INSTALLATION
Open the unit by pressing button P(fig. 3) while at
the same time pulling in the direction of the arrows.

Insert three new alkaline LR03 penlight AAA 1.5V
batteries of the same type. Pay attention to polarity
as shown on the bottom of the housing (fig. 10).
ATTENTION. Inserting the batteries the wrong
way round could damage the unit.
If the symbols on the display do not appear
within 30 seconds, press the reset button R
(fig. 54)
Close the unit making sure that the hooks are
inserted into the 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 heating
mode ().
The room temperature reading and battery status
indicator now appear.

ATTENTION. Whenever the thermostat door is
opened for making adjustments it is then neces-
sary to close it correctly so as to avoid running
the batteries down unnecessarily (fig. 60).
4 - THERMAL DIFFERENTIAL
The thermal differential is adjustable from 0.1°C to
0.9°C.
THERMOPROGRAM is supplied ready to operate
with a thermal differential of ±0.2°C.
This thermal differential is suitable for systems with
high thermal inertia, for example, installations with
cast aluminium radiators.
If the characteristics of the system make it necessary
to change this value, follow these steps:

7 - AUTOMATIC OPERATION
At initial switch-on the thermostat starts in AUTO-
MATIC operating mode.
If the thermostat is operating in MANUAL mode
press button (fig. 21) to switch to AUTOMATIC.
Move the sliders 0 ÷ 23 (fig. 22) positioning them in
correspondence with the desired temperature for
each hour of the day.
Each time a slider is moved the display will show the
temperature set by that slider and its position (fig. 23).
Programming can be modified at any time by
simply moving the sliders to the desired position.
mode will be activated. In cooling programme mode
the temperatures that can be selected are in the
range 18°C to 31°C
Selecting a value above 31°C causes the system to
turn off. This will be indicated on the display by the
appearance of the OFF symbol within the temper-
ature field. When operating in cooling mode the
symbol is animated.
In heating programme mode the temperatures that
can be selected are in the range 6°C to 24°C
When operating in heating mode the symbol is
animated.

ies down unnecessarily, close the door.
8 - MANUAL OPERATION
8.1 - Switch from AUTOMATIC to MANUAL mode by
pressing the button (fig. 24) (the symbol on the dis-
play reflects the selected mode).
8.2 - Rotate the control (fig. 25) to the desired tem-
perature (refer to the 6 ÷ 24°C temperature range for the
heating programme and 18 ÷ 31°C for the cooling pro-
gramme). The thermostat will remain in this operating
mode as and until AUTOMATIC mode is reselected.
ATTENTION. The temperatures are only dis-
played with the door open. When not adjusting

9 - MANUAL TIMED PROGRAMME
If a fixed temperature is to be maintained for a few
hours or a few days (for example, to maintain a
comfortable temperature for a longer period when
unexpected guests arrive, or when an economical
temperature is required during long periods of
absence), MANUAL TIMED programme mode can
be activated. Once the desired duration has been
set, the device starts a countdown. When it reach-
es zero, the unit switches from MANUAL to AUTO-
MATIC mode, resuming the set programme.
Programming by the hour
9.1 - Select MANUAL operating mode and set the
desired temperature using the rotary control (fig. 26).
9.2 - Press button (fig. 27).
In place of the current time h01 will appear.
9.3 - Press the or buttons (fig. 28) until the
desired number of hours is reached from 1 to 99.
The hours count includes those when program-
ming is performed. The remaining part of the hour
when the operation is performed is therefore
counted as one hour.
Note. To return to AUTOMATIC operating mode

In place of the current time d01 will appear.
9.6 - Press the or buttons (fig. 32) until the
desired number of days is reached from 1 to 99.
The days count includes those when programming
is performed. The remaining part of the day when
the operation is performed is therefore counted as
one day.
