AC fan control

[Razrbk]

Last night, I switched my AC fan settings from High to Auto (CCC2 thermostat). Zone 1 went into Auto just fine; however, Zone 2 would not (stayed on High mode). Zone 2 compressor works fine as well as the fan's Low, Med, High and Off settings. Help on this would be appreciated. ----- Thx, Mike

If room temp is 4 degrees higher then set point the fan speed will be on high in Auto once below 4 degrees it will automatically change fan speed to low. This could be the case with your Zone 2

Not the problem, but thanks for responding.
