Does Nest work with 2 stage heat pump?
Best answer: Yes. The third-generation Nest Learning Thermostat supports up to three stages of heating and two stages of cooling for most homes.
What temperature is a heat pump not effective?
Heat pumps do not operate as efficiently when temperatures drop to between 25 and 40 degrees Fahrenheit for most systems. A heat pump works best when the temperature is above 40. Once outdoor temperatures drop to 40 degrees, heat pumps start losing efficiency, and they consume more energy to do their jobs.
Why is Nest using AUX heat?
If the Nest thermostat is displaying “Aux Heat” instead of simply “Heat” when you are warming your home, it probably means that it is extremely cold outside and your heat pump is using a secondary heating source in order to keep your space warm.

What’s the difference between RH and RC on thermostat?
The RH wire refers to “red heating” which means that this is the connection you need in order to power the heating system of your air conditioning unit. The RC wire, on the other hand, refers to “red cooling”. It’s the same with the RH wire in that it powers the thermostat. For the RC, it powers the cooling system.
What color is the OB wire?
It’s usually blue, but it may also be black, brown or purple. The O or orange wire connects to your heat pump (if applicable).
How do I know if my heat pump uses an O or B wire?

What wires do you need for nest?

What is the difference between a 1 stage and 2 stage heat pump?
A single stage-compressor only lets the heat pump cool/heat at full blast. A two-stage compressor allows the heat pump to cool or heat at different levels: High (full blast) and low for milder days. Well two-stage heat pumps run more often, while using less energy.
How can I tell if Nest is compatible?
Go to g.co/nest/cwire for details. To check for compatibility, you only need to know the type of heating system. The specific brand or model doesn’t matter. If you don’t know what type of system you have, check your manufacturer’s website or contact them.
