    I would just get another thermostat, they are cheap. You have a very nice furnace! enjoy

    You’ll need separate thermostat for each unit. How’d you duct the Harman? Did you hook up to the existing duct or run a separate one? If you used the existing duct you need isolation dampers on the supply of the old furnace and new furnace.
