The second stage is the full capacity of your system . 1/3 compressor capacity is the 1st stage. 1st stage is more efficient than 2nd stage, but systems are designed to use both stages, so no worries there.
What does it mean when your thermostat says stage 2?
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.
What is the difference between a 1 stage and 2 stage thermostat?
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. ... Two-stage heating requires a two-stage gas valve and a variable-speed blower motor.
What does Stage 1 on a thermostat mean?
A single stage heating or cooling system means your furnace or air conditioner has only one level of heat or cold output. Single stage thermostats are used to control single stage HVAC systems—thus, if you have a single stage heating and cooling system, your home needs a single stage thermostat.
Is my furnace 1 or 2 stage?
A furnace with single-stage heating contains a fixed gas valve and a single-speed blower motor. These furnaces are either on and running at full capacity or off. A model with two-stage heating contains a two-stage gas valve and a variable-speed blower motor.
What is a 2 wire thermostat?
If we put it simply, a 2 wire thermostat is one which has only 2 wires coming out of its backside. ... When it comes to low voltage systems, a 2 wire thermostat is usually known as a “ heat only thermostat ” and is used for systems like a gas furnace (with only heating option).
Is Stage 2 Cooling high or low?
Two-stage cooling means the air conditioner or heat pump has a compressor with two levels of operation: high for hot summer days and low for milder days . Since the low setting is adequate to meet household-cooling demands 80% of the time, a two-stage unit runs for longer periods and produces more even temperatures.
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 I know if I have 1 stage cooling?
Conventional Single stage systems – will have one wire leading into W or W1 terminal (for heating ) and one wire leading into Y or Y1 terminal (for cooling ). So that's the easiest way to identify single stage conventional hvac systems (which would be furnace based or boiler based).
Does a 2 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.
What does heating stage 2 mean on Trane thermostat?
A 2-stage furnace with a 2-stage thermostat will begin in first stage ( low burner, low airflow ) and only go to second stage if the indoor temperature drops during first stage. ... This provides greater humidity control, quieter operation, and maximum air circulation, temperature distribution, and air filtration.
What is a staging thermostat?
The staging is at the point . An ‘up-stage' or a ‘down-stage' of a thermostat is defined by the difference between the room temperature and the thermostat setpoint. staging occurs at a fixed interval from the setpoint with this type of thermostat.
What is the advantage of a 2 stage furnace?
The more consistent airflow achieved by a 2-Stage Furnace results in quieter operation, more even temperature, enhanced indoor air quality, and increased furnace efficiency .
Is a 2 stage furnace worth the extra cost?
While it is true, a two-stage furnace costs more when it comes to purchasing and installation , and it will save you money long term. It also reduces temperature fluctuation at the house and will heat the home and let it cool when it is less cold outside and work in a more “intelligent” way than a one-stage furnace.
Are 2 stage furnaces quieter?
A two stage furnace is quieter and generates more even heat through the house. The longer, slower heating cycle eliminates the kind of rapid warming that many people find uncomfortable from a single stage furnace.
