Okay, but Needs a Little Work

I replaced another brand of wi-fi thermostat with this one after the original failed. I bought the Honeywell partly because of the reviews and partly because of the company reputation. It works, but I am a little disappointed at this point. The thermostat does not update the indoor temp properly or often enough so it gets cold in the house before it turns the furnace on and then it overruns the set temperature so it gets too hot inside before the furnace turns off. I thought it was a problem with the unit so I returned it and got another. No difference. I called the support number and got someone overseas who had no idea how to understand the problem or tell me how to fix it. In addition, the unit does not have a function to give me daily unit run times. On the plus side, it is easy to set up and the display is easy to read. I would give this unit 5 stars if it would work correctly and give me some idea of how much the furnace runs on a given day.

Update, one year later. The unit has settled in as far as holding temp goes, and I like the feature where it anticipates the heat time needed to meet the temp setting at a given time. Especially useful given that we reduce the house temp to 60 degrees overnight in winter. The unit senses temp drop during the night apparently and calculates the time needed to meet the warm up time in the morning. I would give it 5 stars but there is still no function to view actual run times.

Purchased a Honeywell “Smart Home” color thermostat to replace a builder installed Honeywell thermostat on our hi-efficiency (95%) gas furnace/AC unit. The original thermostat worked well, but the display was just too small to comfortably read, and programming, with no WiFi feature was extremely(emphasis on extremely)difficult. The large color display on the new thermostat is excellent. The app seems to work well, however after only a few days of use, I’ll reserve total judgement for now. I have noticed that the outside temperature reading does not seem to update very often, and the displayed outdoor temperature rarely is even close to three remote reading thermometers we have in our home. I have noticed that the furnace cycles more often than it did with the previous system, and the thermostat has no choice of temperature differential settings. There is a conventional/hi-efficiency setting, which I have set to the hi-efficiency setting. It would be my choice to have a couple of degrees differential between on and off, so the unit didn’t cycle so often. I do plan on contacting my HVAC supplier to find out if there are any adverse effects from the more frequent cycling. At this writing, I am about 3 months from using the AC part of my system, so may add to this review at a later date. Summary, to thermostat manufacturer, or app developer, this really need a differential choice.

So far it’s the best I’ve had..and I had a few..

I just installed a new Carrier high efficiency furnace in our vacation cottage up north Michigan. I had bought a $99 Honeywell RTH6580 at first, installed it and found out it didn’t have any battery backup. Since it’s a vacation home, I want the thermostat to remember the settings because I’m only there if you times per year and the power seems to go out regularly. No where could I find anything about a backup system, so I tested it by turning the furnace off for a while and reconnecting. The thermostat went to a much higher (probably a preset) heat setting than I had it. So that thermostat came off the wall and went back to the store. Then I tried a $99 Sensi. It was very difficult to set up, I never could get it to connect plus it only went down to 50° and I needed to go down to 42 because that’s the temperature I keep my cabin in the winter. So they one came off the wall and went back as well. I then bought the Honeywell RTH9585. It stores settings in permanent memory, not just limited battery back up, which is great because sometimes power is out for several hours, and no batteries to change. its goes down to 40, was really easy to set up and connect to my router, app has worked flawlessly. I love it so far. And I’m getting a $50 rebate from the electric company for installing it...awesome.
