duel furnace control

I'm thinking of replacing a Williamson Oilsaver 224,000 B.T.U. output with 2-125,000 Thermopride low boys. The unit now has 2-5 ton coils side by side. I'm looking for a control that will alternate furnaces on call for heat so its not just one unit running until the outside "T" calls for both to run.  ( I know they have a control for boiler's. )

    Lead lag control

    How about using a Honeywell T775? You could use it for lead lag, and set up an outdoor air sensor for reset control.
