M600C25 Chatham Brass/Mears Line-Voltage Thermostat, 1H/1C, 55-85 degrees F
Replace a compatible line-voltage thermostat used for direct electric heating or cooling control. Confirm the complete equipment model, system type, heating and cooling stages, power or voltage, terminal labels, auxiliary/emergency heat requirements, and wiring before ordering. A similar-looking thermostat is not proof of compatibility; some systems require a common wire, adapter, or approved control.

How to find your model number: Read the thermostat model number on the front, behind the faceplate, or inside the sub-base. Also photograph the terminal wiring and locate the furnace, air-handler, or heat-pump model label. Verify the complete equipment and thermostat details before ordering.
