Total Connect Comfort Software

Last year I had to replace the entire first floor HVAC system. The company providing the new HVAC system also removed my old Honeywell programmable thermostat and replaced it with another brand name thermostat. I didn’t think much about it at the time as I thought I was getting an updated thermostat. It was a horrible mistake! With two different manufactures of smart thermostats trying to adjust temperatures in the house, in short, was not working! I finally got mad and replaced both of them with these new Honeywell units. I really like the iPhone interface with both units. It is extremely easy to program and very versatile. My home is maintaining a much better comfort level while not having two HVAC units fighting for control or one not running at all. I am a little disappointed that Honeywell will not provide a common interface between the two thermostats. Ie. Both HVAC units should be running at same time so that one unit is not carrying the entire load of the home. If one unit is on, the other will not since a need to operate (at least for a little while). But, I’m not an HVAC engineer and there may be other issues here, such as a confused homeowner. Regardless, these two thermostats seem to balance my home much more effectively and efficiently than my previous set up. And the two HVAC units seem to get along with each other now. So, 5-star because they are working better than I expected!

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.

I don’t understand why when you try to do a temporary override of the system the maximum time you can override is 3 hours. When you pull up the screen to override it, it shows the maximum adjustable end time as the time until the next program starts which would be great. Once you set it to override until the next program period you think everything is ok but if you go back in to review it the override has reset to 3 hours from the current time. Today is Thanksgiving and the business will be unoccupied and I want to override the system all day until the night setting kicks in. Unfortunately all I can do is override for a maximum of 3 hours at a time. This has been going on for over a year and I would think it would be corrected by now. UPDATE: After doing some more digging I found out that the thermostat itself has a setting that can limit the length of any override. The app would submit the override request but the thermostat would limit the duration to 3 hours. After changing the thermostat setting for the maximum override time to 12 hours the app worked flawlessly. Also found out the thermostat has holiday settings that allow any holidays you pick to have a different schedule.
