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
- 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.
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.
