How does a 2 stage thermostat work?

A two-stage thermostat increases efficiency by running the first-stage burners as long as possible. If the first-stage burners cannot maintain a 6- to 8-degree temperature rise in the house, the thermostat fires up the second-stage burners.

What does Stage 2 Cooling mean on thermostat?

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.

Does a 2 stage furnace need a special thermostat?

The short and simple answer is no, yet it comes with a few caveats. Although a regular thermostat will work with a 2-stage furnace, there are different factors to consider. Read on for information that could help you decide whether it is worth it to keep an existing thermostat for your 2-stage furnace or to upgrade.

What controls the operation of a two stage furnace?

The furnace’s control board and thermostat are responsible for controlling valve position. After reaching the programmed temperature settings on the thermostat, the furnace shuts down. On extremely cold days, when extra heat is needed, the valve opens fully and runs full blast until the desired temperature is achieved.

How do you wire 2 stage cooling?

Connect the wires of the 2-stage thermostat to the household wires. Connect the red wire to the “R” terminal of the thermostat; the brown wire to the “W2” terminal; the black wire to the “C” terminal; the yellow wire to the “Y” terminal; the green wire to the “G” terminal; and the white wire to the “W” terminal.

What is the difference between a 1 stage and 2 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 are the benefits of a two stage air conditioner?

How often should a 2 stage furnace cycle?

Have you ever wondered, “How often should my furnace cycle?” There’s no set answer. On average, furnaces should kick on and off anywhere from 3-8 times per hour. However, if your furnace does so more frequently, don’t assume it’s short cycling just yet.
