Difference sensor

Using two sensors a differential thermostat can be created. When the difference in temperature between both sensors
reaches a certain value, a relay channel can be activated.
To achieve this, the one sensor must know the address of the other one (see paragraph on differential thermostat).
1. Push the 'Location' button until the first sensor of the
differential thermostat is displayed.
