Schluter is a name you trust for underfloor heating, and this thermostat is the brains of the entire system. Its built-in GFCI protection is the crucial detail. It’s a safety device that monitors for electrical faults and shuts the system down if one occurs. This isn’t an optional accessory; it’s integrated, which means a cleaner install and one less component to wire separately.

The 3.5-inch touchscreen feels responsive and modern. Programming a heating schedule is straightforward, and the energy tracking feature gives you a clear read on consumption. It controls both 120V and 240V Ditra-Heat systems, making it a versatile single solution for different rooms. You set it and largely forget it, which is the point.

Be prepared for the installation. This is a hardwired unit requiring a dedicated electrical circuit, so professional help is recommended. The interface is clean, but the depth of programming options means you’ll spend some initial time with the manual. For a permanent, set-and-forget heating control with critical safety built-in, it delivers exactly what Schluter users expect.
