Do you need a 2 stage thermostat?
To sum it up: 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 is the difference between single stage and two stage thermostat?
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 type of thermostat do I need for a two stage furnace?
Normally a two stage furnace would require a four or five wire thermostat, and the thermostat would control the call for heat, by mode and stage.
How many thermostat wires do I need for a two stage furnace?
It'll require 2 wires for power & it has wireless capabilities. A relay control board can be installed in the furnace and configuration is easy & unbelievably expansive. You can put multiple averaging sensors through the house, and outdoor temperature sensor for setback, etc.
Does a 2 stage furnace require a 2 stage thermostat?
If it's a two stage furnace then it should have a two stage thermostat, to operate most efficiently.
Is it worth getting a 2 stage furnace?
The two-stage furnace is more efficient than the one-stage because it doesn't release as much fuel into the heat exchanger when the home is only somewhat cold. If it's 5 to 10 degrees outside, a two-stage furnace will run in the partially-open position and only use 70% of the energy it normally would.
How do I know if my thermostat is compatible with my furnace?
If you have any doubt about which type of thermostat is suitable for your furnace, refer to the furnace owner's manual or contact the furnace manufacturer. Thermostats may also come with documentation that indicates what type of furnace they can be used with.

What does Stage 2 mean on a thermostat?
What is meant by Stage Two heating? When the thermostat on a dual-stage furnace reads “Stage 2,” it implies that the furnace is operating at the higher setting, giving you 100 percent of its capacity. Usually, the lower setting of a dual-stage furnace is sufficient to provide household comfort almost 80% of the time.

How do I know if I have 1 or 2 stage heating?
How to identify your heating/cooling system? To know whether you have a single-stage or multi-stage system, check the number of wires leading into different terminals of the thermostat. A multi-stage system will have lots of wires to the thermostat whereas a single-stage system has only a maximum of two wires.
Why does my thermostat say Stage 1 and 2?
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 Stage 2 mean on a thermostat?

How do I know if my furnace is 2 stage?
Identifying a multistage system2-stage conventional heating will have wires leading into the W1 and W2 terminals.3-stage conventional heating will have wires leading into the W1, W2, and W3 terminals.2-stage conventional cooling will have wires leading into the Y1 and Y2 terminals.
How many conductors to run to a T-stat?
Your best bet is to run an 8 conductor wire to a T-stat with two stage heat and two stage cool and also hook up a common wire to the 2 Stage Thermostat.
How many conductors do I need for an outdoor condenser?
Out to the outdoor unit you would need 4, but if it were me I'd run a 6 conductor wire out to the condenser just in case one those breaks you'll have an extra couple of wires to make repairs if needed.
Does a furnace stage up or down?

Can an Amana furnace use a 2 stage thermostat?
there is a two stage Amana furnace that will not accept a 2 stage thermostat...I am checking now to see if this is the model and the best thermostat that controls both heat staging and cooling staging for the AMEC96...
What is a jumper on a furnace?
Other furnaces have a jumper that tells the control whether there is a 1 or 2 stage t-stat. Most furnaces can control staging as well as most t stats, so you don't loose much having a 1 stage t-stat on a 2 stage furnace in most cases IMO.
Do all 2 stage furnaces have t-stats?
Not all 2 stage furnaces, installed with single stage t-stats, work the way that you described. Upstaging is not simply based by timing. It is logic based.
Can a 2 stage furnace be a 1 stage furnace?
Some 2 stage furnaces can be installed with a 1 stage t-stat and still operate as a 2 stage furnace if w1 and w2 are jumped together. When the control receives a simultaneous call for both w1 and w2 it knows that the t-state is single stage. In such a case it will use logic to upstage based on run time to satisfy.
Can Amana have 2 stage stats?
The H models of Amana cannot have a 2 stage stat, only one on the market like them. They do as they please so could be erratic. I don't buy the crap that a timer can stage a furnace better than a good 2 stage stat that knows what the house needs. Timers bring on high just when the house is warming up.

I recently had a Lennox EL296V furnace installed, along with a Honeywell T6220 thermostat. The furnace and thermostat are both configured as 1-stage. The furnace does the two stage thing using a fixed timer.
Comments (17)
I had the same thing happen and I was mad as anything. Mine is Carrier and I had even questioned how the 2-stage would work and the guy explained it blahblahblah, to me it sounded like the stat would control it.Little did I know they didn't wire stat for 2-stage.
Can a Goodman furnace be controlled by a thermostat?
The 2-stage/variable speed goodman furnace (gmvc96) doesn't allow the stages to be controlled by a conventional 2-stage thermostat, which is very important if you want to use the furnace to it's potential without blowing hundreds on the comfort-net digital communicating thermostat.

How many stages does a smart thermostat have?
Since this is a smart thermostat, I did go through the software menu, and changed the settings so that it is aware that the equipment consists of 2-stage heating and 1-stage cooling.
Can you use a dip switch on a 2 stage thermostat?
I did not touch the ACRDJ jumper, it is only to be removed if 2-stage cooling is present, at least that's how I understand it. (As an aside, I tried with and without and it didn't make any difference)
Is Energate Foundation a real thermostat?
Edit (Oct 2021): Just thought I'd add a bit more info to my own answer. Turns out this Energate Foundation tstat isn't a " real" smart thermostat. It never turns on the 2nd stage heating, at least not how I expect it to. I figured it would turn the 2nd stage on if the 1st stage was not able to bring the temperature up to setpoint within a given time.
Does the thermostat energize Y1 or Y2?
Ok so I figured it out. I probed the pins on the back of the thermostat to see which pins were being energized when it was calling for cooling. Turns out it energizes Y1, not Y2. Makes sense since it does support 2 stages for both heating and cooling. So I have my "cooling" wire at the Y1 terminal at the thermostat and Y/Y2 at the furnace. This wiring allows the cooling to work at the required high flow. Works as expected now. Final revised wiring diagram below.
