A two-stage thermostat may need more wires than your current programmable thermostat. If you plan to keep your home at a constant temperature, you don't need a two-stage thermostat. If you want to vary the temperature of your home during the day or night, a programmable two-stage thermostat is the way to go. Two-stage heating means the furnace has two levels of heat output: high for cold winter days and low for milder days. Since the low setting is adequate to meet household heating demands 80% of the time, a two-stage unit runs for longer periods and provides more even heat distribution. How to Hook Up a 2-Stage Thermostat Cut the power to the heating and cooling system at the circuit breaker. Pull or unscrew the body of the existing thermostat from the wall. Install the faceplate of the new 2-stage thermostat. Connect the wires of the 2-stage thermostat to the household wires. The difference between a one-stage and a two-stage furnace lies in their ability to control heat output. Single-stage heating requires only a fixed gas valve and a single-speed blower motor. This kind of furnace is either on or off. Two-stage heating requires a two-stage gas valve and a variable-speed blower motor. A two stage furnace is NOT more efficient than a single stage furnace. It will not save you any money on your utility bills compared to a single stage furnace. Furnace manufacturers do not claim there is an efficiency gain with two stage furnaces.
