Will it work with your system?
Works well with
- App control of baseboard heat
- Room-by-room electric heat
Check first if you have
- Furnaces, boilers and heat pumps (24 V)
- Loads above its rating
What it controls
The meross MTS200 Smart Line-Voltage Thermostat is a smart line-voltage for electric heat that runs at line voltage (120 V per the maker).
Its maker rates it for 1,920 W. At 120 V that covers heaters totalling about 1,920 watts (watts = amps × volts). Check your heaters' load.
Connectivity: Wi-Fi, so the schedule and setpoint can be changed from a phone.
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 0.9 in (D) x 3 in (W) x 4.6 in (H), a weight of 7.4 ounces and a lcd.
