Does a two stage furnace need a special thermostat?

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.

Does Nest thermostat work with 2 stage?

Nest Learning Thermostats are only compatible with systems that have one or two stages of cooling. The Nest Thermostat E is only compatible with one stage of heating, one stage of cooling, and an additional stage of either heating or cooling.

What is a 2 stage heat thermostat?

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.

Can you use a single stage thermostat on a 2 stage furnace?

Any two stage furnace will have a control board that can be adjusted to use either a single or 2 stage thermostat. The control board will simply time the second stage if you use a single stage thermostat.

How much money does a 2 stage furnace save?

The DOE test procedure shows fuel savings of 3.4\% for two-stage furnaces relative to single-stage furnaces at the same AFUE, while the 2006 ASHRAE test procedure shows only a 0.4\% decrease in fuel consumption.

Can I use a single stage thermostat with a 2 stage furnace?

What is 2 stage cooling?

Two-stage cooling refers to the type of compressor that’s in the outside condensing unit. This feature allows for two levels of operation depending on your cooling needs — full capacity on hot summer days or part capacity for milder days.

Do 2 stage furnaces run more often?

Two-stage furnaces run for longer, steadier periods than single-stage furnaces do. This lets them better regulate the home’s interior temperature.

How do you install a 2 stage thermostat?

How to Hook Up a 2-Stage Thermostat

1. Cut the power to the heating and cooling system at the circuit breaker.
2. Pull or unscrew the body of the existing thermostat from the wall.
3. Install the faceplate of the new 2-stage thermostat.
4. Connect the wires of the 2-stage thermostat to the household wires.

Does a 2 stage furnace use more electricity?

For two-stage designs, the DOE test procedure consistently shows a reduction in energy consumption by about 3\% compared to single-stage furnaces at the same AFUE level. In contrast, the 2006 AHRAE test procedure shows almost no difference in the total energy consumption at the same efficiency level.
