American Standard freedom 90 limit control


I have a American Standard 90 two stage that starts the main blower at or around the same time the gas lights. I understand there are dip switches that controls this, but in what configuration. The upper one has two switches and is labeled sw 1, the lower has three switches and is labeled sw 2. I would like it get at least a little bit warm before the blower starts.

Thanks

Look in the install manual if you have it.

Did you install a new thermostat recently? If so it may be set for electric heat and starts the fan instantly. Usually there is a switch on the back of it E or G. Put it to G (gas) or check the programming info.
