What is an underfloor heating floor sensor?
A floor sensor is a device that is connected to the thermostat, and allows the floor temperature to be fully controlled.
The floor sensor is wired back to the thermostat, and connected to the “NTC” terminal. There is no polarity on the cables.
DEVI always recommends installing a floor sensor. The DEVIreg Touch / 550 / 535 / 540 thermostats can be programmed to operate as any 1 of these 3 options:
- Air sensing
- Floor sensing only
- Air & floor sensing
A Floor sensor must be installed when floor or floor/air sensing is chosen. Without a floor sensor, the maximum floor temperature cannot be controlled. A floor sensor is essential with wood, vinyl or carpet floor coverings.
