Nest Learning Thermostats are only compatible with systems that have one or two stages of cooling. The Nest Thermostat E is only compatible with one stage of heating, one stage of cooling, and an additional stage of either heating or cooling.
Nest activates stage two every time it turns on to maintain the set temperature. This constant use of both stages has significantly increased temperature swings and makes the house much less comfortable.
Secondly, can Nest thermostat control 2 zones? Google Nest thermostats are usually compatible with zoned systems, including zoned systems with dampers. When multiple thermostats control one system, the house is divided into zones using dampers in the ductwork throughout the house.

How does a two 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.
How many volts does a Nest thermostat need?

When it is cold outside, it is fine for your system to have long run times.
Do you need 2 Nest thermostats?
Nest thermostats can certainly be used in conjunction with zoned HVAC systems. However, you are indeed going to require multiple Nest thermostats throughout the house.

Should I use RC or RH nest?

What is the difference between nest and nest E?
The major difference you need to know is that the Nest E doesn’t support Nest’s Farsight tech. It’s the feature that can sense you walking in the door, will wake up the thermostat, and can override any energy-saving settings you might have programmed for the times you’re not home.
Does nest work with my HVAC?
