I chose the Honeywell system over about 3 others that I spent time on Amazon and Google reading about. I originally was looking at the Ecobee system. One main thing that stopped me was the remote stats that I wanted to have on the system. The outdoor temperature and outdoor humidity stat would have required me to pull wire to a location for each of the devices. Also each of those devices are costly for outside use. (Humidity is the most costly) There remote stat that contains both Temperature and Humidity was a breeze to install and better yet I could make sure that it was well out of way of direct sunlight. The other sensors such as the indoor remote sensor that contains temperature and humidity was also simple to install. I have two sensors located in my house, the main is on the 1st floor and the 2 remote is on the 2nd floor. The system does a average for my house. Also the reason for the Honeywell over others....Ecobee has some great features that I have seen used on other places, like the ability for GUI access via a webpage, but the downside to Ecobee, all sensors other than the main unit have to hard wired to the main board and added sensors such as return air temperature and supply air temperatures will need an add on board to the system. Since my Honeywell system has been running, I have actually found that my system spends a fair amount of time in standby mode versus I had a Hunter type of programmable stat before and my system would run constantly.
The interface is simple and straight forward on setup and guidiance on other parts of the system. I know that Honeywell wishes a installer to install their system, but then again, everything you buy the manufacturer prefers they install the product for you. I can say if your installation is different than the all the ones that they list in their manual, then I would consult a local installer, but otherwise, simple as making pie.......

If you are reasonably handy (if you've every re-wired a light fixture for example) you can do this.I ordered this unit with some concern since it is listed as "professional install", but after taking the plunge I found the actual installation pretty simple.
The biggest issue is getting the wiring correct. I'm pretty handy with a hammer and saw, but wiring diagrams aren't my thing. That being said, I was able to hook the whole thing up in about 2 hours. If I did it again though, it would probably take 30 minutes.
My setup was: forced air furnace, central air, and bypass humidifier. The wiring diagrams were clear enoughwhat really tripped me up was that my humidifier wasn't working to start withI just didnt' realize it.
Once I got that fixed, the installation was simple.
Everything wires into the EIM unit which you place near the furnace (or wherever you want) and then you run 2 wires only to the thermostat.
Actually communication between the EIM and the thermostat is wirelessthe wires are just for power.
One tipcut a short length of 2-wire and set up the thermostat next to the EIM while installing. Then you can pair it and do all the setup work without running all over the house. Then when it's all the way you want it, you can move the thermostat to the final installation location.
The remote control is fantasticour master bedroom is often colder than the rest of the houseby having the remote override the wall unit in the evenings, we can keep that room at the right temp. Looking to add an indoor sensor to help even that out long-term, but the remote is a great short-term solution.

No dislikes here at all. It was fairly esy to install on my natural gas heat/electric AC furnace. The instructions were pretty clear just read them!The iPhone interface is great, and simple to use, but you'll need to buy the Red link gateway for internet connectability. Everything works seamlessy and easily. Highly recommended!!
