as of late,we have been installing a lot of york 2 stage furnaces.these are new home installs as well as retrofit installs.am looking on some input as to the best way to operate the 2 stage.at work we use the timer on the board to set 1st stage to run for 10 minutes.is it better to use a 2 stage thermostat?2 stage thermostat is a tough sell to a volume home builder, but to a retrofit application it should be an easy sell.gotta install a 2 stage for my sister next weekend so i can experiment with hers to see what is better as well.
thanks
