What it controls
The Schluter DHERT104/BW Floor Heating Thermostat is a floor heating for electric heat that runs at line voltage (240 V per the maker).
Its maker rates it for 15 A. At 240 V that covers heaters totalling about 3,600 watts (watts = amps × volts). Check your heaters' load.
As a floor-heating thermostat it typically works with a floor sensor; the floor system's maker specifies which thermostats it supports, and that comes first.
Connectivity: Wi-Fi, so the schedule and setpoint can be changed from a phone.
Line voltage can kill: switch the breaker off and confirm it's dead before touching the wires, and use a licensed electrician if you're unsure. Line vs low voltage.
Also on the listing: dimensions of 7 in (D) x 4 in (W) x 4 in (H), a weight of 5.6 ounces and a digital.
