Important information for safe usage

Thermostat:

Manufacturer's guarantee does not cover malfunctions caused by mechanical damage, improper installation,
or exploitation for purposes, or under conditions, not provided by the User- and Installation Manual. Please keep in mind that the Installation
Manual and the Connection Diagram are no replacement 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 the connections and power networking of the device. Switch off power before connecting wiring to the thermostat or disconnecting the
device for testing .

Start-up:

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 damage of the
floor decorative cover and heating mats, or sections outage. In case of doubt contact your dealer or heating system manufacturer.

Function

The 720 thermostat is designed for the control of electrical underfloor heating systems (heating mats or cable units) or other electrical indoor
heating systems. It automatically maintains a specified temperature exactly when you need it. There is no need to think about your heating man­agement. You will never have to remember to turn it on. You only need to set the time when you need it, and the 720 thermostat will turn the heat
on for you so far in advance that the required temperature will be achieved by the time you specify. The 720 thermostat is an intelligent and self­developing system. Its operation is based on its particular experience of heating your house, so it strives every time to execute your commands
more and more precisely and efficiently. The thermostat is equipped with a large highlighted LCD-Display with extended indication that makes it
very easy to use the device. 3 multifunctional control buttons are located under the display; a help string appears in the bottom part of the display
which indicates the current function of the buttons.
The highlight appears when pressing any button and turns off automatically 40 seconds after the last button is pressed. The 720 thermostat
controls the temperature based upon data received from the floor temperature sensor (included in the package). The device displays two tem­peratures — the actual floor temperature and the « set by you» temperature.
The display also shows the maintenance mode (continuous, daily or weekly schedule). In the bottom part of the display the current day and time
are displayed. The device has self-diagnostics, and will display warning messages. You can set a limit of maximum floor temperature. The device

will also show energy saving statistics per day, per week or per month in the form of a percentage figure.

Start-up of the thermostat

The thermostat can be turned on after wiring connections are complete and tested. To turn the 720 thermostat ON/OFF press the middle button

[Button ] for not less than 3 seconds.
Turning ON/OFF is accompanied by an appropriate animation on the display. After the 720 thermostat is turned on the basic indication appears

on the highlighted display.

The larger numbers (20°C) indicate the actual
floor temperature, the figures in the upper left
corner (23°C) show the floor temperature to
be maintained (the «comfort» temperature),
the sign in the upper right corner indicates the
continuous temperature maintenance mode.
This symbol informs you about the
operation status of the heating system (the
heating is powered when the symbol is
visible).

When the 720 thermostat is turned on for the first time it starts working in the maintenance mode (factory setting +25°C). When turned on, with
your selected settings, the 720 thermostat starts working in that mode and will retain those parameters until you change them.

You can change the preset floor temperature by pressing for increasing and for reducing. This value will remain set, as the comfort
temperature in all the modes, until you change it again. To activate the device press, and hold, any button. The buttons are not active, i.e. their

first button pressed only «wakes up» the device and turns on the highlighting.

720 thermostat installation manual

* Important: Switch off the power before connecting or disconnecting wiring to the thermostat. A qualified electrician trained to current Indoor

Electrical Equipment regulations must install all wiring. We strongly recommend that you NOT to 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 be installed in a neighbouring “dry room”.

Please study this manual carefully before starting the installation.

Tools and materials required for thermostat installation:

- Corrugated plastic tube not less than 16mm in diameter; the length depends on the distance between the thermostat and the heating
unit

- Standard junction box for wall mounting units

- Screwdriver

- Phase voltage indicator

Installation of floor-mounting temperature sensor

The floor temperature sensor is installed when you perform your heating element (mat or cable section)
installation. The Sensor is connected to the thermostat via a junction box. Place the sensor in the
corrugated plastic tube near its end, and seal this end of the tube to prevent penetration of water, tile
fixing mixture 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
between two neighbouring passes of this cable. Place the tube in a prepared groove in the floor and

lead its other end to the place chosen for the thermostat or junction box location.

Thermostat installation

Preparation of electrical connections

Install the plastic junction box into the wall where the location 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.

Connection diagram

Menu structure of the thermostat

To control the device, and the setting of its working parameters, the thermostat is provided with a graphic menu, subdivided into parts according to
