View Full Version : Does Anyone Have An Ecobee Smart Thermostat Enhanced?

I'm trying to set a 2 degree cool differential on my new Ecobee thermostat. That means the AC is triggered to turn on when it exceeds my target temperature by 2 degrees. Nearly all thermostats are set by default to turn on at 0.5-1.0 degree differential. This causes the AC unit to turn on and off constantly, wears on the equipment, and is energy inefficient. For the life of me, I can't find where to find this setting despite searching online everywhere, even on Ecobee. It's supposed to be in Thresholds, but I can't find it. Can anyone provide help?

I have one but have to let my grandchild do all the settings, I refuse to touch it.

We have one figured out how to keep it in a range we like after multiple tries and are afraid to make any further changes.

Can you go to whoever installed it.

I just tried this on mine in this order: go to your thermostat, tap top right, tap bottom right settings wheel, scroll to settings, tap installation settings, tap thresholds, tap heat/cool minimum delta, set and then your ready to go. Mine was set to 5 assume that is the default setting? BTW, the available range in the setup is 2-10 degrees.

If you follow the link posted above, the most important step is to change the “Configure Staging” from auto (which is the default) to manual. Took me a long time to figure this out.

Took me a long time to figure this out.I was not sure what that is or does so I looked it up (screen shot). Not sure if automatic would have much bearing on the thresholds (does not say so). I am going to try mine on 2 degree difference vs. 4 and see what happens.

Personally I don’t even use the auto feature. Just turn on plain, old-fashioned AC or heat as appropriate. I couldn’t get the deadband function to work well either. I bailed and went manual…

Yes!! This is how to do it. Then you'll see Cool Differential Temperature in the next menu with a sliding scale which can be set to +2.0 (or whatever) as I wanted. None of the 3 AC techs that were here even knew what I was talking about. For others to know, the heat/cool minimum delta setting is something different and is default set to 5.0 F.

Call their help line, great people there. They will walk you through it.

We have that thermostat and it works great. You can set it to just Heat or Cool or Auto. In the Auto mode for example we set the heat side to 70 and the cool side to 76. It seems to work very good. You don’t want those numbers to be too close together as that will not work. If you want to maintain the same temperature no matter what say 75 then you will have to just switch back and forth between Heat and Cool depending on the weather forecast. Right now the weather is a bit crazy where a cold day pops up about once or twice a week. Send me a PM if you need help.

That is pretty much how we set it on auto. Was surprised how long it took to set up and than explain to us how to use it. Wish they would have give us some sort of cheat sheet but we are happy with it.

I think in automatic mode you have to have a five (5) degree differential between cool and heat to prevent the HVAC unit from cycling on and off. For example:

Heat 68 and Cool 72
Heat 69 and Cool 73...

If you try to enter something less than five (5) degrees it changes the other setting automatically.

I use the manual mode, either set on heat or AC.
I turn it up/down to my comfort....easy peezy

When I turn it off completely is when I open the windows in the house.

Isn’t it easier to use the app, instead of manually making changes on the thermostat?

I hate new technology. We got one of those dam things with our new HVAC system. The instructions that came with it were 1) download the app 2) register it and create an account, and 3) follow the instructions on the app ????? What instructions? Now Ecobee sends me texts to try to sell me stuff. Today they said I need to replace the filter and wanted me to buy it from them. Where the #$&* is the printed owners manual with a table of contents that leads me to the page that explains what I’m looking for information about? I miss our simple and reliable old analog thermostat.

We tried

I had the app installed, selected wants and needs. Tech came about a week after we closed, was a little surprised she didn’t have to add the app, and do extensive tutorial.

She did however disable the + mode, explaining that less active households don’t benefit from the + feature.

I don’t receive any emails selling products from company, only notifications that filter needs change, or humidity is high.

I believe this is what " the heat/cool minimum delta " actually sets
If (for example) you set minimum delta to two then you can do (example)
Heat 70 and Cool 72
Heat 69 and Cool 71...

The "delta" value is defining how close together the heat/cool setpoints are allowed to be.
At least on my Honeywell this is the case.
Other values change accordingly.
For example, if you set a delta of two, the "range" must be .5 or 1.
Otherwise the aforementioned back and forth heat/cool issue would ensue.
