Setting of room temperature
1. Make sure actual room temperature is shown in the display.
2. Press the up/down selector to set the desired room temperature value. SET is shown in the display.
3. When releasing the up/down selector the display returns to actual temperature.
Note: The thermostat regulates the floor heating system
according to room temperature set point, within the maximum and minimum limitations defined for the floor surface temperature.
Room temperature limitation
1. Make sure actual room temperature is shown in the display.
2. Press the push button until SET MAX is shown in the display.
3. Press the up/down selector to set the maximum room temperature limitation.
4. Press the push button shortly, SET MIN is shown in the display.

Floor surface temperature limitation
1. Ensure actual floor surface temperature is shown in the display illustrated by .
2. Press and hold the push button until SET MAX is
also shown in the display.
3. Press the up/down selector to set the maximum
floor surface temperature limitation.
4. Press the push button shortly, SET MIN is also
shown in the display.
5. Press the up/down selector to set the minimum
floor surface temperature limitation.
IMPORTANT!
As heat emission from the floor may vary slightly depending on floor covering - and thereby cause inaccurate temperature measurement - it may be necessary to adjust the setting of max. and min. floor surface temperatures accordingly. It is important always to follow recommendations from the floor manufacturer regarding max. floor surface tempera­ture. It is recommended always to include mixing shunt for floor heating circuits in order to ensure optimal flow tempera­ture. - In addition to minimised energy consumption, correct setting of the flow temperature will eliminate the risk of excessive heat transfer to the floor.
