In applications where both floor heating and radiators are present in the same room it is possible to control
both using only one thermostat if the following conditions are fulfilled:
1. The room thermostat must have a floor sensor installed.
2. Min. 2 outputs have to be assigned to the room thermostat, of which min. one output must be connected to
