What it controls

The Honeywell Home RLV3150A1004/E Line-Voltage Thermostat is a line-voltage for electric heat that runs at line voltage (120 V per the maker).

Its maker rates it for 3,000 W. At 120 V that covers heaters totalling about 3,000 watts (watts = amps × volts). Check your heaters' load.
