3 zones on a 2 speed Rheem 17 SEER system

The board, zone controls and motorized bypass has worked flawlessly for over a year. I am testing a wireless Honeywell stat in my bedroom and it works great with it.

I had to buy the 3 ton system which took me 1/2 ton higher than the old system because it was not made in the 2.5 ton. I cut in my garage and did not zone it. I put a hand operated damper on the garage run.


This helped me deal with some static pressure relief. My garage is really nice now if I do work there and this in my opinion was a win/win thing.

Glad to hear you are enjoying your system!

If you are interested, we now sell a wire thermostat, Model EWT-3900
