Connecting the temperature sensor
Connect the wires of the temperature sensor to the terminals on the rear side of the thermostat (no
polarity needs to be respected).
Note: Do not install the floor probe immediately next to a heating element. Insert the probe between
the heating cables (it mustn’t touch them), approx. 20 cm deep into the heating area, as close to the
surface as possible. The cable of the temperature sensor mustn’t lie across the heating cables.
Setting the maximum temperature of the floor
Check the set temperature of the floor during the installation of the floor sensor. The recommended
value is 27–33 °C (depending on the type of room). To adjust the setting of the maximum floor
temperature, press the adjustment button (you can see the position of the button in the picture) using a
pointed object and the or arrows.
1.2 Configuration of switches
a) Early Start function, known as Fuzzy Logic
The thermostat has a built-in function which enables the calculation of the optimum
time to start the heating system to achieve a desired temperature at the programmed
time. Set the E.S. (No.1) switch to “ON” for the activation of this function.
b) Temperature in °C or °F
The default configuration of the thermostat is in °C. If you want to change the setting to °F,
move switch No. 2 up. If this change is made, don’t forget to change the comfort and
economy heating settings as well.
POWERING UP THE THERMOSTAT
When the thermostat is switched on for the first time, the
display will show the time 0:00, the temperature, and the
manual mode ( ) symbol. If the thermostat is defective or
doesn’t comply with the instructions, other information may
appear.
If the temperature sensor is defective, or if the temperature is
lower than 0 °C or higher than 60 °C, the message LO or HI
will appear on the display. If the LO message is displayed,
the heating indicator will also appear and the relay will be
closed (the current is going in the load).
