After removing the rear panel 

of  the  device,  the  following 
factory  default  settings  can 
be  modified  by  relocating  the 
jumpers  (black  plugs)  located 
on the base panel.

3.1 Modifying the Switching Sensitivity

The switching sensitivity of the thermostat can be selected or 

adjusted by the uppermost jumper.

The factory default switching sensitivity (the difference between 

the  adjusted  temperature  and  the  temperature  measured  when 
the device is switched on or off) is ± 0.2°C that can be modified to 
± 0.3°C by relocating the plug onto the left and central pins.

3.2 Changing the Unit of Measurement of the  

 

      Displayed Temperature

The  unit  of  measurement  of  the  temperature  shown  on  the 

LCD display can be selected and set by  the central jumper.

With factory default settings the display shows the temperature 

in  °C  (Celsius)  which  can  be  modified  to  °F  (Fahrenheit)  by 
relocating the plug onto the left and central pins.

3.3 Changing the Displayed Temperature

The temperature(s) to be shown on the LCD display can 

be selected and set by the bottommost jumper.

With  factory  default  settings  the  display  shows  the 

currently measured room temperature value, while the notice 

ROOM

” appears in the bottom right corner of the display. The 

adjusted  temperature  is  visible  only  during  the  adjustment 
process  (for  approximately  15  seconds).  By  relocating  the 
plug onto the left and central pins the displayed temperature
