Customer Reviews for Honeywell Home - T9 Smart Programmable Touch-Screen Wi-Fi Thermostat

It is very convenient to adjust the thermostat remotely through the app. After working through the programming and set up it has become very beneficial...I also use the remote temperature sensors to balance out each level in the house. I am very pleased with the system.
No, I would not recommend this to a friend.

Disappointed - No U1 or U2 wire connections
on February 18, 2025
Posted by: Don't be misled
The heating and cooling functions work fine but if you need a thermostat to control ventalation or a humidifer using a U1 or U2 connection, this is not the one for you. While the wiring diagrams and images on this site show it has U1 and U2 wire connectors, when I received my thermostat, it does not. The installation instructions say very clearly it will not work for U wire connections. So... which is it?
It is very misleading to show the connections. Had I not needed to use the new thermostat for heat because it was -4 degrees outside and I was going out of town, I would have definitely returned it just because I don't appreciate the inaccuracy, whatever the reason.

Hi, thank you for your review of the T9 Smart Thermostat. This model cannot control humidifiers, dehumidifiers or ventilators. We recommend you reaching out to your HVAC contractor to install a T10 or other trade model compatible with these products.

Great thermostat when it is connected to WiFi. Mine is connected but not showing connected on the app so I can't run it from the phone.

Initial wiring was extremely difficult with the provided instructions. After much research, I was eventually able to get the thermostat to heat and cool, but it ended up being a matter of trial and error with the wiring. I am apparently one of many who have had this problem when trying to follow the wiring instructions when the hvac unit is a heat pump. The thermostat now will heat and cool, but will still not run the emergency heat. I am going to have to call an hvac technician to troubleshoot the problem.

The T9 is just perfect for our house. We have return vents on each room, and frequently recirculated, but our rooms would still all be too hot or too cold. With this and the remote temp sensors, it's allowed our house to be comfortable everywhere where we're at.

Install was easy. Use at the device/controller is flawless. We continue to have wifi/app issues. If we make changes via the app, which is one of the main reasons we got this unit, they frequently do not translate to the actual controller. This is a major downside to our use-case. Would I recommend? Maybe, but with a bunch of warnings and caveats.
No, I would not recommend this to a friend.

Great stat when it works

It's a great tstat when it works. I have had multiple times watching it reset. Sometimes it just turns off and I get up and pull it off to reset it. I'm probably going to get a power monitoring meter with data recording so I can prove to honeywell that the Stat socks and it's not the furnance.
No, I would not recommend this to a friend.
