Schluter is known for high-end tile installation systems, and their Ditra-Heat-E-RS1 thermostat brings that same engineered focus to smart floor heating. This isn’t a generic smart thermostat retrofitted for floors. It’s purpose-built from the ground up for the precise, reliable control that under-tile systems demand, with integrated GFCI protection as a core safety feature.

The mirrored finish and app control deliver a modern smart home experience. You can set schedules, adjust temperatures from anywhere, and use voice commands with Alexa or Google Home. The real value is in the energy tracking and dedicated floor sensors. These sensors give the thermostat a precise read on the actual floor temperature, not just the ambient air. This prevents the system from overworking and provides accurate, efficient heating exactly where you want it. It handles both 120V and 240V systems with a 15-amp capacity.

Installation requires compatibility with Schluter’s Ditra-Heat-E-HK heating cables. For some larger rooms, you may need an additional power module. It’s a premium controller for a premium heating system, designed for those who want seamless integration and detailed management of their heated floors.
