Allowed me to upgrade to smart thermostats and their customer help line is excellent.
Nick Murray•February 25, 2017
Outstanding. I wanted to replace my standard thermostats with smart thermostats (Nest upstairs and Honeywell Lyric T5 downstairs) but controller board that was installed in my house was not compatible because it did not supply power to the thermostats. So the solution I tried was to swap out the cheap controller with this product, pretty much wire for wire and it worked perfectly. Now the smart thermostats work as they should and I have this cool controller that has lights to show how everything works. Also side note I called the Smartzone customer help line while installing and they were extremely helpful which was pretty cool for a product that cost me less than $200.
So far so good! Very easy to configure

Was a replacement for a White Rodgers unit that failed after 12 years. So far so good! Very easy to configure!
Outstanding Product

Purchased this product to replace a Honeywell board. This controller is simply amazing! The instructions are clear and concise! The LED lights provide the information you need to track the behavior of the control circuit. I cannot stress how important that is when stepping through the setup with your thermostats. I highly recommend this product regardless of you personally performing the installation or not.
This product is a work of ART!
One Note: if your original system only has 1 control transformer, go ahead and purchase one. You should have a dedicated transformer for the board.

Works as described. Only down side is this model can't control a bypass damper. I should of bought the 4x model.
Works great, easy to install.

My local HVAC company wanted $600 to install a new zoned panel. My old panel had a master and a slave so the upstairs would only kick-on if the downstairs needed to. I had this thing wired up and two new thermostats installed in about an hour.
I was a little nervous to do this own my own but it turned out to be a lot easier than I anticipated.
Not only was this easy to install, this is a much nicer panel than what my HVAC contractor was going to install.
My wife was getting hot so I ordered next day for 8.99 and it got here on time. Got to love amazon and its sellers.
