## Long description

The Thin Bed heating set DANFOSS DEVI 1-450W 140F0820 is a complete underfloor heating solution for tiled floors covering approximately 3.0 m². The set contains a 450 W heating cable mat sized to match small to medium bathroom or kitchen areas and the DEVIreg Touch thermostat for precise temperature control. The system is intended for embedding in thin-bed tile adhesive and delivers uniform radiant heat to reduce cold spots and improve floor comfort in both retrofit and new-build projects.

How to use

Connect the heating mat to the DEVIreg Touch thermostat and fit the temperature sensor in the recommended position within the tile adhesive. After electrical connections are completed by a qualified electrician and the system is tested, cover the mat with tile adhesive and finish with chosen tiles. Program the DEVIreg Touch for desired temperature schedules and calibrate the floor sensor if required.
Usage recommendations
For reliable performance and safety, have all electrical connections and commissioning performed by a licensed electrician.
