5 Ton AC - 2 Zones

Hi everyone,

I have two bays side by side, and I'm hoping to cool them both by a single 5 ton heat pump system.

I would like to mount the air handler in the attic, near the wall joining the bays, and branch the intake and exhaust to each bay with dampers.

Bay #1 needs AC / Heat so intake and exhaust comes from bay #1 and bay #2 closed - vice versa.

Will I be able to achieve this with two thermostats, and four dampers?

If so, any recommendations on the best thermostats to use - and if possible for them to be smart (controlled by phone as well as thermostat)

I uploaded a drawing here - https://docdro.id/NuUImiT

Much appreciated diyers!
