What it controls
The Honeywell Home TH115-AF-GA/U Floor Heating Thermostat is a floor heating for electric heat that runs at line voltage (120 V per the maker).
The listing doesn't state a maximum load. Don't install it until you've confirmed the rating covers your heaters' total watts. How to work out the 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 0.9 in (D) x 2.8 in (W) x 0.9 in (H), a weight of 0.05 kg and a digital.
Warranty, per the listing: No warranty.
