I would go with the honeywell setup. It's not something you can pick up at HD, but at a local hvac supply house. I don't know your knowlge of wiring controls, but in general, it would be best to get a hvac guy to install it. If done incorrectly, a lot of time can be wasted.

Good luck

Yeah, the Vision-Pro is the type I recommend. A little pricey, but seeing as this is a 15-20 year investment, it's worthwhile. (easy to say when it's not my money):whistling

Granted, it's been two months since that post, and I totally misread that. I was under the impression that it was one air handler. I still think there is one air handler. I can't imagine two air handlers with one duct system. But, it does say two seperate t-stats. I hope the coil is in the return...

I wonder how they set it up originally.
