The number of degrees difference before switching.  

The default is 1°C which means the thermostat will switch  

the  heating on 0.5°C below the set temperature and will turn 

it off 0.5°C above the set temperature.With a 2°C differential  

  

the heating will switch on 1°C below the set temperature 

and will switch off 1°C above the set temperature.     

This is to recalibrate the temperature if required. 

This alows the temperautre to be set to show °C or °F.
