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 man-
agement. 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 self-
developing 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 tem-
peratures — 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.

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
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.
