I recently installed two nest thermostats. One to control the temperature on my first floor and the other to control the temperature on my second floor.
However, I can’t seem to get the units to control the dampers and the air isn’t being pushed out through the vents.
I have C, G, Y, W, and R wiring set up on both thermostats. Any advice on where to look or how to correct so they control the dampers?

Hello RunnerAround,
Thanks for reaching out here in the Community. Some zoned systems rely on the thermostat to control the opening and closing of the dampers to control the flow of air throughout the home. If you have multiple dampers controlling the flow of warm and cool air to zones in your home, your system may be compatible with the Nest thermostat as long as your system only uses standard thermostat wires.
However, some damper systems use proprietary wires that aren’t compatible with Nest thermostats. For example, if your current thermostat has wires labelled MISC or Damp, it is not compatible.
If you need help determining if your damper system is compatible, contact a Nest Pro in your area.
To learn more, you may check our public article “Zoned system compatibility with Nest thermostats”.

Emerson

Thanks - I was eventually able to figure it out. The wires on the damper control panel needed to be adjusted slightly
