Product Data for T498A,B Electric Heat Thermostats (English) PDF ↗

T498B1512 has been discontinued by the manufacturer (2026-04). Suggested replacement: TH114-A-240D-B - Non-Programmable Line Volt Thermostat for Electric Heating (DPST).

The T498B1512 is a line-voltage thermostat from Resideo (Honeywell Home) for electric resistance heat — baseboard, convectors, radiant ceiling or panel heaters.

Line voltage is the distinction that matters here. A low-voltage thermostat switches a 24 V control circuit and lets a furnace or boiler do the work; a line-voltage thermostat carries the full heater current itself. They are not interchangeable, and a low-voltage stat wired to a baseboard circuit fails immediately.

Match the voltage and the pole configuration to the heater circuit, and check the amperage of the heater against the rating of the thermostat. A thermostat sized below the load is the most common cause of a line-voltage stat failing in its first season.
