Temperature difference

Convectors often have a built-in fan for faster heating. This setting determines how much the temperature needs to drop
below the desired temperature in order to switch on the convectors' fan(s).
The temperature difference is also used for the differential thermostat (see paragraph on differential thermostat).
1. Press the 'Location' button repeatedly until the
desired sensor or zone for which the temperature
difference will be set is displayed.
