The Empire Wall Thermostat, Reed Switch, part number TMV, is a manual wall thermostat designed to control compatible millivolt heating appliances. It regulates room temperature by opening and closing the millivolt control circuit as the temperature rises and falls relative to the set point. This thermostat is intended for simple, dependable temperature control in systems that do not require external power for thermostat operation.
This thermostat mounts on an interior wall and connects to the heater’s millivolt control terminals using standard low-voltage thermostat wiring. A reed-switch style control provides consistent circuit switching for millivolt gas valves and related millivolt control systems. Installation should follow the appliance manufacturer’s wiring diagram to ensure proper operation and safe heater cycling.
What’s Included: One (1) Empire TMV wall thermostat with reed switch and mounting hardware.
Installation Limits: For millivolt control circuits only; use low-voltage thermostat wire and install on an interior wall away from drafts, direct sunlight, or heat sources; follow the heater manufacturer’s wiring and safety instructions.
Compatibility: Compatible with Empire millivolt heaters and fireplaces that accept a 2-wire thermostat input, including Empire direct-vent wall furnace lines such as DV210/DV215 and DV25/DV35 series that require a wall thermostat.
