“Installed about 2 weeks, wifi is a nice feature. Easy to program. The only thing I set a temp and it has a memory as to how long it will take to reach desired temp.”
“Installed very easily. I'm using this with a single furnace single AC system. This can control multiple but seems complex. I went with this over the lower models because it already had wifi and did't require the Honeywell gateway to connect to the internet. Once you register the system online with Honeywell, you can then download the app or control the thermostat from a web browser. Very easy to control. Hopefully it will work with the home automation system that I choose in the near future.The only downfall is that if you want remote sensors in bedrooms or other levels of the house, you have to run wiring. No wireless indoor sensors are available. Also, there is only one remote sensor input which means that all of the sensors have to be tied together. You cannot measure the the temp of each remote sensor separately. The indoor sensors are just small resistors and have to be wired together very specifically to accurately tell the average temperature of the combined rooms. Depending on the amount of sensors you have, you may have to wire them in series, parallel, or a combination of both. It can be very confusing if you do not have a background in circuits. So, because the thermostat doesn't have multiple sensor inputs, you could possibly have an issue if you have a sensor in a cold room and a sensor in a warm room. The thermostat will average them and think those rooms are fine. You are then stuck with adjusting the room's dampening vents by how the room feels instead of accurate temperature readings. I bought three sensors, because I had three bedrooms upstairs, and decided to return one after reading how difficult it was going to be to run wiring between the sensors to make sure they are both in parallel and in series. Check out the wiring diagrams on the manual http://siglercommercial.com/wp-content/uploads/2013/08/HONEYWELL_REMOTE_SENSOR_C7189_INSTALL.pdf I decided to install two sensors and will adjust the air vents based on feel for each room. It should do the same thing and keep the rooms very comfortable, just more manual effort.For this reason I give it 4 stars instead of 5. Give us a total of three remote sensor inputs, as most people have three bedrooms or three separate zones they want to monitor, and it is easily a 5 star thermostat.”
“Works great and connects to the internet via WiFi for weather information. I like that I can lock out the compressor/electric heat at certain temperatures.”
“My customers love the easy programming features, the "TOTAL-CONNECT" WEBSITE & PHONE APP FROM HONEYWELL (for remote access) and of course the 5-year factory warranty.”
“Very good thermostat. Installer documents are not the best but the thermostat is not hard to program or use. The challenge is understanding the terminology.”
“I have sold this Honeywell thermostat without the Wi-Fi feature to several commercial customers and have not had any issues with them. They are all still functioning well and performing the tasks for which they are designed, controlling rooftop commercial HVAC units. I love the easy tech setup via the touch screen and the amount of features it has gives me the ability to install it on many different types of systems. This Wi-Fi version is a nice upgrade that gives the ability to monitor and control the thermostat from off site locations. Some business customers who manage multiple locations will find this option invaluable. I purchased this Wi-Fi enabled thermostat to install in a home that I have under remodel. It has proven to be just as robust, feature rich and reliable as the non Wi-Fi version and I could not be more pleased with it. Setup was easy via the touch screen tech setup menu, as with the non Wi-Fi version, and the pale blue back light is more pleasing on the eyes than the green or amber lights of most touch screen thermostats. Honeywell makes a few versions of this thermostat and you need to know what type of system you are wanting to control with it before you buy. For example, if you have a 1 heat and 1 cool system such as an electric or gas furnace and a regular air conditioner then you would purchase the Honeywell TH8110R1008 Vision Pro 8000. For more options like a heat pump system with electric or gas backup heat you would purchase one with 2 heat and 1 cool or the one I am reviewing here, the TH8321WF1001, which has 3 heat and 2 cool options. Either way you cannot go wrong as long as you understand what type of system you are controlling. A few more pluses to this thermostat are the 7 day programming, the auto switchover function and the remote sensor hookups. You have the choice of using the programing ability or using it as a set it and forget it thermostat, which means that you are not forced to program a thermostat or press the "hold" button every time you need to change the temperature set points. You can use remote sensors on this thermostat and control the temperature based on the reading from another room where the remote sensor is installed. You can install a remote outside temp sensor to stop a heat pump from operating when it is too cold outside. You can even install a humidity sensor inside and use the humidity control feature of this thermostat to keep the humidity level from getting too high inside. Probably the most impressive feature though has to be the auto switch over ability. The auto switchover feature lets the you set heating set points and cooling set points and the thermostat will automatically switch from heating to cooling as needed according to your set points, no need to manually change your system from heating to cooling on those warm spring days or back to heating that same night when the temperature drops to the low 50's. This feature is so handy I wonder why thermostat makers do not included it in all of their products. Pros: Reliable, easy to setup, pleasing to look at and feature rich in an affordable thermostat. Cons: You must have a common wire from your furnace to power this thermostat, this thermostat has no battery compartment and uses the furnace transformer for power. It is highly recommended to have this thermostat installed by a professional for this reason and to properly program the tech functions to match your heating and cooling system. I have been pleased with this thermostat and highly recommend it to anyone wanting a feature rich and reliable thermostat to control a variety of heating and cooling systems.”
