How do two thermostats work together?

When multiple thermostats control one system, the house is divided into zones using dampers in the ductwork throughout the house. When one zone needs heating or cooling, the damper for the ductwork in that zone opens, guiding the warm or cool air to that zone.

    Can 2 thermostats work together?

    The question is whether it is possible to use two thermostats to control one Zone. Yes, in principle, you can use two thermostats to control one HVAC zone.

    Do I need 2 thermostats for 2 zones?





    If your home has more zones than a single, smart thermostat can support, you’ll need another one. For example, you may have a thermostat for the upstairs and downstairs portion of your home.

    What is twinning on a furnace?

    Twinning is defined as two identical model residential gas furnaces connected to a common duct system. We strongly recommend the heating and cooling equipment is always properly sized based on an acceptable heat loss/gain load calculation.

    What is a 2 stage 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.

    How do multi stage thermostats work?



    Multistage systems work like a ceiling fan with different speeds: low, medium, and high. Instead of simply switching on heating or cooling, they can adjust the temperature of the air pushed through your home’s vents to reach the temperature you set as efficiently or as quickly as possible.

    What does Stage 1 and 2 mean on thermostat?

    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.

    Identifying a multistage system

    1. 2-stage conventional heating will have wires leading into the W1 and W2 terminals.
    2. 3-stage conventional heating will have wires leading into the W1, W2, and W3 terminals.
    3. 2-stage conventional cooling will have wires leading into the Y1 and Y2 terminals.


    Does a two stage furnace run all the time?



    On average, a 2-stage furnace runs on high about 25% of the time. A 2-stage furnace runs for longer periods of time because it’s running on the low setting BUT this type of operation provides a more even heat distribution so it reduces air fluctuations or cold spots in your house.

    Do you need a special thermostat for a two stage furnace?

    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.
