What it controls

The Honeywell Home YRLV4300A1014 Line-Voltage Thermostat is a line-voltage for electric heat that runs at line voltage (120/240 V per the maker).

Its maker rates it for 1,749 W. At 240 V that covers heaters totalling about 1,749 watts (watts = amps × volts). Check your heaters' load.

This isn't a 24-volt job. Turn the breaker off, check with a tester, and hire an electrician for anything you're unsure of. Why baseboard heat needs its own thermostat.

Also on the listing: dimensions of 1.5 in (D) x 5 in (W) x 5.75 in (H), a weight of 11.2 ounces and a lcd or led.
