What it controls

The Cadet 8734 Line-Voltage Thermostat is a line-voltage for electric heat that runs at line voltage (240 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.

It's single pole. Single-pole models break one leg; the heater stays connected to the other.

Connectivity: Wired, 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 30 in (D) x 8 in (W) x 6 in (H), a weight of 5.6 ounces and a manual.

Warranty, per the listing: Warranty.
