UNDERFLOOR HEATING H YSTERESIS 

Underfloor heating hysteresis defines the tolerance for the maximum and minimum temperature. The settings range is 
0,2°C to 5 °C. 

If the floor temperature exceeds the maximum temperature, the underfloor heating will be disabled. It will be enabled 
only after the temperature has dropped below the maximum floor temperature minus hysteresis value. 

Example: 

Maximum floor temperature:  33°C 
Hysteresis: 2°C 

 When the floor temperature reaches 33°C, the underfloor heating will 
be disabled. It will be activated again when the temperature drops to 
31°C. 

If the floor temperature drops below the minimum temperature, the underfloor heating will be enabled. It will be disabled 
after the floor temperature has reached the minimum value plus hysteresis value. 

Example: 

Minimum floor temperature: 23°C 
Hysteresis: 2°C 

When  the  floor  temperature  drops  to  23°C,  the  underfloor  heating  will  be  enabled.  It  will  be  disabled  when  the 
temperature reaches 25°C.

MAXIMUM FLOOR TEMPERATURE 

In order to set the maximum floor temperature, activate the underfloor 
heating and press MENU until the maximum floor temperature settings 
appear  on  the  screen.  Use  PLUS  and  MINUS  to  set  the  temperature. 
Confirm by pressing MENU button (confirm and move on to edit the next 
parameter) or EXIT button (confirm and return to the main screen view). 
Changes will also be saved automatically after 5 seconds of inactivity.

MINIMUM FLOOR TEMPERATURE 

In order to set the minimum floor temperature, activate the underfloor 
heating and press MENU until the minimum floor temperature settings 
appear  on the  screen.  Use  PLUS  and  MINUS  to  set  the  temperature. 
Confirm by pressing MENU button (confirm and move on to edit the 
next parameter) or EXIT button (confirm and return to the main screen 
view).  Changes  will  also  be  saved  automatically  after  5  seconds  of
