What this thermostat is built to run
- Before bringing it home, add up your cable amperage at 120V or 240V. If it exceeds 15 amps, plan for the additional power module.
- Check that your wall box and finished wall depth can take the thermostat body and its wiring pocket.
This is the control unit for an electric floor heating system, not the heating itself. It switches 120V or 240V cables up to 15 amps, so it fits many small to mid-size rooms when the total cable load stays inside that limit. If your planned area pulls more, Schluter lists a power module to extend capacity.
We recommend this for someone already laying Schluter heating cable who wants app and voice control plus energy tracking. The color screen makes local adjustments easy, and the class A GFCI is a genuine floor-heating requirement rather than a bonus.
What the $240.00 price means
The thermostat is $240.00. The typical price over the last 90 days has been $278.40, so this runs about $38.40 under that average, roughly 14 percent. It is a steady discount rather than a clearance event, and there is no record-low figure to point to here.

The ongoing questions to settle
The app tracks energy usage, which helps you see how much the floor actually draws. What it cannot tell you is your electricity rate, so the dollar cost per month depends on your utility and how long you run the heat.
Two practical checks before buying. Confirm your home Wi-Fi reaches that spot, since app and voice features need a stable connection. The 3-year limited warranty is conditioned on installation per Schluter's handbook and data sheet.
When this thermostat is the wrong fit
Skip it if you have not chosen a heating cable system yet or if your total load exceeds 15 amps and you do not want to add the power module. It also is not the right part for hydronic or forced-air heating, since it is built to switch electric floor cable.
One more pass point. If you want a thermostat that works without a phone or Wi-Fi, this one leans on the app for its energy and smart features, so check how it behaves locally before you commit. We'd consider it best for a single-room Schluter electric floor where the load fits and the app is welcome.
