Works perfectly!
The screen is large enough and lights up well at a touch for easy viewing. The fact that I'm able to pre-program my preferred temperature settings, and make changes via WiFi using an App on my iPhone or iPad, is a plus, too. But what really sets this thermostat apart for me is my ability to set up security on it and lock the screen so that no-one can just walk up and change the temperature settings. This is great!! I haven't used it yet, but there is also an "Auto" mode which when chosen allows the thermostat to decide whether it necessary turn on the Air Conditioner or the Heat to meet the preferred temperature setting. I would've given it a 5, but the security code used to lock the screen is preset by Honeywell and cannot be changed, so that is just one more thing I have to figure ...

Sure would be nice if Honeywell will allow the user to create their own code in the future.

Ho-hum product but it works. The web interface is the best part.
Boring interface, somewhat difficult to program. The web interface is great and easy to program. I use the web interface extensively. But this product should be half the price. And it should be a consumer install. I had to have a professional install it and he took 3 tries to get it right. This whole market segment is ripe for standardization and innovation. Unfortunately, this product is very average.Boring interface, somewhat difficult to program. The web interface is great and easy to program. I use the web interface extensively.

East to Install, Convenient to Use
This is a current top-of-the-line standard WiFi 7-day programmable thermostat. Honeywell makes it easy to install with installation videos on YouTube.It is easy to setup by just following the installation manual which comes with the thermostat.You can manage it (initial program and changes) online or through a smartphone app. You can set alerts for a variety of different conditions. No extra batteries are required. It gets 24v power from proper wiring.This is a current top-of-the-line standard WiFi 7-day programmable thermostat.

Very Versatile and Feature-Rich 'Stat!
First off, this Wi-Fi Vision Pro 8000 'stat was an upgrade from a 2013 non-Wi-Fi Honeywell Vision Pro unit that came as part of my 4-Ton Carrier 16-SEER 2-Stage Heat Pump/AC unit install back then. So, the mounting wall plate screw holes were the same and the wiring was to the identical letter terminals (C, Y, W, R etc.) on both units. I did have to replace the old wall-plate with the new one that came with this 'stat. Regardless, I would recommend taking a cell-phone pic of your old 'stat's wiring/terminals just to have a reference before you start. I would also recommend reviewing the install and owner's manuals BEFORE you start, just to better familiarize yourself with the connections and also the basic system configuration and set-up for your type of system- this is absolutely critical ...

I did have to replace the old wall-plate with the new one that came with this 'stat.

I would also recommend reviewing the install and owner's manuals BEFORE you start, just to better familiarize yourself with the connections and also the basic system configuration and set-up for your type of system- this is absolutely critical for your system to run correctly. Also, you have to register your new 'stat on the Honeywell website during initial set-up, including being able to connect it your home Wi-Fi network/router, etc. It does take a few minutes to do this and the 'stat display screen navigates you through the set-up process, step-by-step. Another great feature of this unit is that it automatically sets the date and time and receives your local outdoor temp. and humidity - all over the internet based upon your zip code- very nice!! AND...no BS about having to install backup batteries either, as it retains your settings if the power should go out. YAY!! I would recommend downloading the Honeywell App on your phone first to start your acct. and then you can add your new 'stat to your account during set-up. This is a very versatile, capable and incredibly feature-rich thermostat that will work on just about any home or business system out there - so just be sure to set it up correctly and you will have an amazing Wi-Fi 'stat for your home or business. I would also HIGHLY recommend looking at and understanding all of the user-selectable features of this unit, as several of them will add to your overall energy efficiency and comfort - making this unit easily pay for itself over time. Also, before you start your installation, be sure to shut your system OFF first and then turn off the power at the breaker panel, just to be extra careful. It's always good practice to do this!! Once you have double-checked your wiring connections to the 'stat terminals and they are secure, turn the power back ON to start the set-up of the new 'stat. Once mine was all set-up, there was a 5 min. system start delay- which I believe may be a default setting on the 'stat that you can change. It did cause me a few anxious minutes, but I did recall reading something about a system start delay while reviewing the manuals. Since I completed the install, I am absolutely delighted with my well-thought-out purchase. As mentioned, this is an incredibly versatile unit; likely the most versatile and feature rich units I found after doing a lot of research!! I made several minor checks and feature adjustments within the first few days or so of getting acclimated to all the great features of this unit. I had only one minor issue where the displayed indoor humidity shown on the display was about 7%-8% higher than my other humidistat units in my home. I was able to find "Offset Adjustments" in the Installer Menu that allowed me to make +/- adjustments to the displayed Temp. and Humidity. Once I adjusted and saved the new humidity settings, the 'stat has been spot-on within 1% of the other humidistats in my home. (My only real minor gripe is that the font used to display the indoor humidity is real small on the 'stat screen and you really have to be close to it to view it.) I also have nice remote visibility using the Honeywell app, which I also love, as I can check my home temp., make temp. adjustments and also set temp. alerts while away from home - very nice indeed! So, everything is working great and I hope to have several years of great service from this Honeywell Wi-Fi unit! I would also suggest checking around the internet on several platforms, as pricing/availability seems to vary quite a bit!

Honeywell Wi-Fi VisionPRO 8000 TH8321WF1001 Ptorammable Thermostat Does It All
Easy to install if you have a "common" wire available. If not you will likely need to pull a new thermostat cable with at least 6 18 gauge wires. There are no replacable batteries for control power & back-up power. Easy to set-up. Warranty requires professional installation though, not sure why. Has most of the capabilities you will need for controlling a heating & cooling system including a heat pump.Easy to install if you have a "common" wire available.
