the Installation Manual and Connection Diagram are no repla-
cement for the professional skill of the device installer. We
recommend that you apply for professional service for the
thermostat and heating system installation. Only qualified
electricians should perform connections and power network-
ing of the device. Switch off power before connecting wiring
to the thermostat or disconnecting the device for testing.
Introduction
Congratulations! Having chosen the I•WARM thermostat
you enter into the world of heating comfort, coziness and
user friendliness. The I•WARM 710 device opens a new
series of SST room thermostats which feature high reliability,
easy adjustment, simple display, and modern design. Our
intention is to make your home heating extremely comfort-
able, cozy, simple and energy efficient. We hope that you
enjoy using it!
Please study this manual carefully before you install
the device!
3

Basic functions
The I•WARM 710 thermostat is designed for electrical
underfloor heating systems (heating mats or sections).
The device automatically keeps the temperature you have
set based on data received from the floor mounted tempera-
ture sensors (included in the delivery set). Both real floor
temperature and the desired value you have preset are dis-
played. Or, at your command, air temperature in the room can
be displayed, measured by the device’s built-in sensor.
Continuous selfdiagnostics are provided, with warning mes-
sages being displayed.
The manual heating control mode can be activated in case
of sensor malfunction, when heating must continue until
the problem is solved.
Startup of heating system control
The thermostat can be turned on after wiring is finished
and all connections are tested.
4

Important: Don’t turn the newly built heating system
on before the tile fixing mixture or cement-sand mortar layer
are hardened. You can get the different hardening times from
the manufacturer of your chosen building material.
Turning on the heating system prematurely can lead to dam-
age of the floor decorative cover and heating mats, or sections
outage. In case of doubt contact your dealer or heating system
manufacturer.

The LCD display lights up and the basic screen appears.
Large figures show the current floor temperature
and the figures in the upper right corner show the preset floor
temperature.
You can change the preset temperature by pressing
the «+» button to increase it and the «-» button to decrease it.
Controls and display
1. Current floor temperature (°С)
2. Preset floor temperature (°С)
3. Heating system is powered on
4. Attention sign (see details on page 11)
5. The «+» button for temperature increase
6. «A/MODE»button for device turn ON/OFF and tempera-
ture indication mode change
7. The «» button for temperature decrease
When the heating system is powered, the appropriate sign
indicating the heating system is ON is displayed. When
the thermostat turns the heating off the sign disappears.

Air temperature display mode
The thermostat can display ambient temperature in your
room instead of floor temperature. At that setting the device
continues to control heating regardless of the display mode.

To switch the thermostat to ambient temperature display
mode you should briefly press the center button (A/MODE).
Large figures now display ambient temperature, and a sign
(fig.3) appears, informing you that the device is switched
to this mode.
To return to floor temperature indication mode, press
the A/MODE button once more. The sign disappears.
Adjustment of built-in ambient temperature sensor
indicator
The Temperature indicated by the built-in sensor can
slightly vary from the actual room temperature because of
small heat output inside the device case.
You can correct this difference by the input of actual room
temperature measured by your thermometer.
We recommend that you make this correction only after
two hours of continuous operation of the thermostat.

For adjustment of builtin temperature sensor indication you
should:
1. Switch the device to ambient temperature indication
mode if another mode was used.

2. Press the «+» and the «-» buttons simultaneously
and hold them for not less than 3 seconds.
A large figure showing current ambient temperature will
flash and a sign (fig.4) appears indicating sensor adjustment
mode.
Pressing the «+» and the «-» buttons set the indicated cur-
rent temperature equal to the temperature shown by your
room air thermometer. At that time the appropriate data shift
is displayed in the top right corner of the screen.
When you are finished with your adjustment you can exit
this mode by simultaneously pressing of the«+» and the «-»
buttons and holding them for not less than 3 seconds.
The device leaves the data shift mode automatically, approx-
imately 40 seconds, after the last button was pressed.
Control of heating system operating conditions
The I•WARM thermostat permanently controls the oper-
ating condition of the heating system. If the heating
of the floor surface to the preset temperature appears
to be impossible ATTENTION sign is displayed.
11

The thermostat permanently controls operability
of the temperature sensor. In case of a malfunction (cut-off
or short-circuiting of connecting wires) during which normal
operation of the heating system is impossible, the thermostat
turns the heating off and displays a warning message (fig.5).
You should contact the manufacturer or your local dealer
to repair or replace the temperature sensor.

Manual heating control mode (Emergency mode)
In case of temperature sensor outage the thermostat
turns heating off. If heating of the room is still required
it is possible to control heating manually for a time period until
the sensor function is restored. To switch to this mode press
the «+» and the «-» buttons simultaneously and hold them
for not less than 15 seconds.

When the sign (fig.6), which indicates the control mode,
appears, the large figures show the average percentage
of installed power being consumed by the heating system.
You can adjust this percentage by pressing the «+» or the
«-» buttons. The changes you make are reflected in the dis-
played value.

I•WARM 710 Installation manual
Important: Switch off power before connecting or disconnect-
ing wiring to the thermostat. A qualified electrician trained
to current Indoor Electrical Equipment regulations must install
all wiring. Failure to do so may invalidate the warranty.
We strongly recommend that you NOT install the thermostat
in premises with high air humidity. It is prohibited to install
the device in bathrooms, saunas, shower cubicles or pools.
The thermostat controlling heating in these premises must
16

be installed in a neighbouring “dry room”. Please study this
manual carefully before starting the installation.
Tools and materials required for thermostat installation:
1. Corrugated plastic tube not less than 16mm in diame-
ter; the length depends on the distance between the thermo-
stat and the heating unit.
2. Standard plastic junction box for wall mounted units
3. Screwdriver
4. Phase voltage indicator
Installation of floormounted temperature sensor
The floor temperature sensor is installed when you install
your heating element (mat or cable section). Place the sen-
sor in the corrugated plastic tube near its end, and seal this
end of the tube to prevent penetration of water, tile fixing mix-
ture or cement mortar during the installation of the heating
system. The tube containing the temperature sensor must be
located at the same level as the heating cable.
17

Place the tube in a preprepared groove in the floor
and lead its other end to the place chosen for thermostat
or junction box. Cut off excess tube length.
18
Fig.8 Installation of floor temperature sensor.

Installation of the thermostat
Preparation of electrical connections.
Install the plastic junction box into the wall where the loca-
tion of the thermostat is planned. Lead the power supply
cable, the cold leads of the heating mat or section, and the
temperature sensor cable, into the box. Turn on the power
to the supply cable and find the phase wire using phase indi-
cator; mark this wire.
Turn the power to the cable off.
All thermostat connection work must be performed only
when the power network is completely disconnected.
Connect all required wires to the thermostat using its ter-
minals with screw fastening.
If you have three-wire power network (with separate
ground conductor) use the connection diagram shown
in fig.9. The heating cable screen is connected to the network
ground conductor by means of the external terminal block
(included in the delivery set), by fastening the appropriate
screws.
