Honeywell WiFi TStat Review
This is a really good product at a good price. I set one up for a friend, and then went out and bought one for myself. After it was wired up, the rest of the process--setting zone temperatures and setting up WiFi and the smart phone ap took less than 15 minutes. The app allows you to look at the current temperature and setting as well as the weather forecast. A nice feature is the setting of min and max temps, and if breaches, you get an email.
The cons: product support --documentation, phone, and email just sucks. Worse than bad. I'm a mature, retired microwave electrical engineer. I had two simple questions--what power was required from the separate 24 vac transformer, and what was the difference between their jumpered R and RC contacts. Either it was a "don't know" or a "you need to be a licensed HVAC installer". My recommendation: make sure you use a dedicated transformer with neither lead grounded. What size transformer? I have no clue, and apparently, Honeywell doesn't either.
