1E78-151 Emerson/White-Rodgers 70 Series Programmable Thermostat
Replace a compatible 70 Series wall thermostat in a residential heating or cooling system. 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.
