I have a 2 Stage variable speed furnace.
The Nest learning thermostat will only operate this furnace on the highest speed which causes air to heat up to fast without heating the rest of the house- floor et. Furnace constant on and off.
Other than fan speed everything else works as intended. Old thermostat was a Honeywell and worked fine but started to go through batteries at a high rate.
Fan speed doesn’t even show up on thermostat under setting or in the app.
CURRENT WIRES: Black, Green, Red & White. All hooked up correctly.
Anybody have a fix.

I hope that these suggestions help resolve the fan speed control issue with your Nest Thermostat.
