Switching differential is the term given to the amount the thermostat will
allow the temperature to vary from the Set Temperature. This feature allows
you to decide how closely the thermostat will control the temperature in the
room. A smaller switching differential will switch the system on & off more
frequently.
Your thermostat is factory preset to allow the room temperature to rise
0.25°C above the Set Temperature, and then it will let it drop 0.25°C below
the Set Temperature (0.5 C differential). This differential can be changed
from 0.5 C to 1.0 C, in which case the thermostat will switch less
frequently.
Example: it's cold outside and the heating unit is running. It has raised the
room temperature to 21°C. Your thermostat has been set to 21°C and the
preset switching differential to 1.0 C. The heating unit will continue running
until the room temperature reaches 21.5°C before shutting off. The
temperature will then begin to drop until it reaches 20.5°C. At this point
the thermostat will switch the heating back on again.

12. PROGRAMMING
The setting of the differential does not affect the electricity consumption of
the heating system. The higher differential causes the thermostat to switch
on and off less frequently, which increases the lifetime of the switch
contacts.
In most cases the factory setting of 0.5
°C is suitable.
When either of these temperatures are reached the
thermostat will switch the heating system off.
Note!
Do not set the thermostat to “Floor temperature limitation mode” if no floor
sensor cable is installed. Pressing the FLOOR SET button will not display the
floor temperature!
