What it controls
The Mysa IN-FLOOR V1-0 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 3,800 W. At 240 V that covers heaters totalling about 3,800 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 0.78 in (D) x 3.03 in (W) x 4.56 in (H), a weight of 499 g and a led.
