Honeywell T5 Wifi Thermostat Wiring Diagram

Bought this in Oct 2018, to replace a standard Honeywell 24/7 programable thermostat and found this very simple to install and use. I emailed support a picture of current wiring and they came back 2 days later with the recommendation for the wiring. Within 10 minutes it was up and running. I use the geo fencing feature and it have learned my setting preferences to provide energy savings.

Took some research to make sure it was compatible, found the right wiring diagram. Installation was easy. Works as advertised. Highly recommended.

The Ecobee was recommended to me by the HVAC guy I had come out to remove the Honeywell thermostat I had installed. Turns out it was defective. The HVAC guy could tell I didn't know much about installing thermostats so he recommended Ecobee. It was also the least expensive of the newer "smart" products. I had no trouble at all putting in the Ecobee and getting it to work. And I love being able to adjust the setting with my phone.

Had an old Honeywell thermostat that came with the home built in 2003. Couldn't tell exact temperature. Wanted s smart thermostat that I could adjust while I was away to save energy. Purchased through my utility company and got a great deal and free install!

Really glad made the decision and replaced my 3 month old Honeywell thermostat thought it was same expensive

[This review was collected as part of a promotion.] I always saw ads for the ecobee smart thermostat but we had a Honeywell lyric so I was hesitant to try this. We love the recyclable packaging the product came in. It was super easy to install. The design is very sleek and I like the display and I love the eco+ and the smart home and away feature to help save money! We’ve only been using the for a few weeks but so far we are happy!

Thermostat was NOT recommended for my 'old' heating system wiring set-up, noting it would probably require a c-wire. After a pretty extensive web search (rather than using the enclosed converter), it was a pretty easy operation (at least for this guy with 'some' experience and a little tenacity) to locate a terminal in the old Aquastat (at least my version) that functioned just fine as a c-wire. Thermostat compatibility with both Alexa and Google Home are both excellent and easy to set-up. Firmware update provided even more features and easy operation for everyone in the home. One of the best tech buys in a long time, especially considering a local gas company $100 rebate! Very cool stuff. Kudos to all at Ecobee.

I had difficulty wiring it, but because the old thermostat was hooked up poorly. Now that the issue was resolved, the unit is great! Easy to use, and remotely as well.

I did a little homework before I installed this thermostat. Took a picture of my wiring as recommended by Nest. The instructions provided were clear and straightforward. In less than 30 minutes my Nest was up and running. Unless you have an old wiring system you should have no issues with this thermostat. The Nest app works great. Gives me full control from a distance.

Nest customer support was very helpful with setting up wiring for my HVAC system with Nest. Systems been in for one week and has been operating well. Also purchased protect as a way to help with the home and away settings of the Nest thermostat. Time will tell to see if the Nest thermostat will save energy cost. Looking forward to it....
