Ecobee 3 thermostat

[BoostAddiction]

I got one of these for Christmas and installed it recently.

As a thermostat it really is quite sophisticated. Has anyone else used one of these? I prefer it to the Nest, which I've played around with.

These are very nice thermostats all the features of the nest. Only problem with the nest is it doesnot work at all or very well with boilers

I haven't used the Ecobee yet. Just done a lot of research into it's abilities. Ecobee's ability to control other equipment like HRVs, and it's ability to intelligently do set backs and recovery make it unique. Because it is weather aware, and has a memory...it really does "learn" how to maximize savings. We need 10 of them, so over the last two yrs I've been waiting for both price and feature set to normalize. The only alternative in our case would be zwave stats, a controller and outside weather station. EEcobee is much simpler and I suspect more reliable.

Our application is 4 zone radiant, 5 air handlers, six AC compressors and two HRVs, all controlled with separate stats right now.

The Nest really doesn't compare as it has zero ability to interface with other equipment, and has no weather-aware "learning".

I just installed one last week, and today got everything working properly.

this thing is really intelligent, and as mentioned, is constantly learning.

we went from a 5/2 programmable Honeywell to this.

there are many great features that the others (honeywell, nest) just don't have, but these are the ones that stick out to me;
you set your temps for when you actually want them, it will learn how long it needs to get from "away" temp to "home" temp, then start the furnace/ac X minutes before so it's ready right at 1750 when you get home.
with above, outside temp is +/-20, it understands it will need to be on earlier/later to reach desired temps
remote sensors. big home/zone heating/only ever in 1/2 rooms... it will ensure whichever room/sensor is "occupied" is @ the desired temp. *may mean some rooms are warmer/colder than others dependent on which sensor is prioritized.
multiple stages/units control. we have AC, Propane furnace, Wood firebox (shares air ducts with furnace) and HRV. While I couldn't get the wood box figured out, everything else is now controlled by the Ecobee... and I'll have to check in with customer service to see if I can get the firebox hooked up... maybe as a stage 2 heating unit?!?!
customization. plan your fan on for 5-20-45-55-?? minutes of each hour, and not straight time, varied through-out the hour. same with HRV unit. get alerts if/when temp drops\rises too much or past X* (if wife cranks it up while I'm @ work)

visually, I like that it is small, simple and yet so powerful.
I'm really impressed so far, and still learning about it.
