Wi-Fi 7-Day Programmable Thermostat is rated 3.4 out of 5 by 40.
Rated 5 out of 5 by from Installed, Connected and Programmed DIY 1 hr. My old Honeywell MagicStat was showing signs of failure (excessive cycling) and Costco had this RTH6500WF WiFi Thermostat for $99. I brought this thing home and read the installation instructions. My previous "MagicStat" did not use a "C" Common wire so I created one with an unused wire in the bundle "Black". I connected it to "C" on my furnace and "C" on the RTH6500WF. It worked. Honeywell makes it VERY CLEAR that this Stat WILL NOT work without the "C" (Common) wire. There are install videos on YouTube that are very helpful. It took very little effort to connect to my network and soon I had apps working on my iPhone and iPad that make programming a cinch.

Rated 4 out of 5 by from So far so good. We have 2 zone units in our home; one gas/AC and one heat pump. I purchased and installed 2 of these thermostats. and in both cases, I needed to configure either the thermostat or the wiring to get a common connection. I was able to follow the available instructions for installation and setting up WiFi with minimal effort, and have been up and running for a couple of weeks. My wife and I used to argue about leaving the house and forgetting to turn down the thermostat, but now I can simply open the accompanying app and control my thermostat from just about anywhere. I'm sure the savings will more than pay for these units in no time.

Rated 1 out of 5 by from Incompatible with my heating system My previous thermostat only had two wires. There was no C wire. After buying three of these thermostats and going through the wiring process on the first one, I come to the part of the instructions that say, this thermostat is incompatible with your system.There need to be warnings on the box at the store. It is too late when you get it home. I noticed there was another one that had been returned to the store and was missing its product ID bar code. That should have been a warning to me.At the very least, the box should tell you to open up your old thermostat to check for compatibility before you even open the box for the new thermostats

Rated 5 out of 5 by from Great Thermostat for the Price! I've been using this Wi-Fi thermostat at home for the last month. Installation took a bit more time then previous thermostats (we didn't have a C-wire and needed to use the G-wire and jumper), but everything went off without an issue. It's held temperature accurately and has cut my electric bill by nearly 10% with my 2-stage A/C in South Florida. Wi-fi connected immediately and set-up was a breeze! Programming can take some time, though.One word of advice - if you do buy this thermostat, do read the setup instructions - they'll guide you through the install process quickly and easily!

Rated 3 out of 5 by from Needs better Support and instructions Installation was straight forward. Setup was not. WiFi would not connect. Sat on hold twice for over 20 minutes but never got support to answer. Online support disconnected with me while I was trying to do what they told me to try. I waited 15 minutes for them to answer me but they only gave me 5 minutes to answer them. Then found a blog online that said your router password has to be less then 10 characters. Changed my router password and it worked. IF the password issue is real why can't honeywell tell you that?

Rated 5 out of 5 by from Works Great Easy to install and works great! I put 3 of these in (2 in one house, 1 in a vacation house). The main house had gas heat so I didn't have to change any default settings. The vacation home has an electric heat pump so had to change a couple of settings. Other than that, set up was a breeze and I can now control both homes via the app or website. And it is much easier to program different on/off days & times using the app than doing it on the actual unit. Fantastic product and I'd buy it again in a second.Other reviews indicate that if the t'stat is put on permanent vacation hold you can't change it via the app. Honeywell must have fixed this because I have no problem taking it off permanent hold and changing the settings.

Rated 5 out of 5 by from Easy Installation and Setup I had the old thermostat removed and the Wi-Fi one energized in less than 1/2 hr. The work-around for lack of the C wire was not necessary (but available) since I found an extra wire in the wall. Pairing with the Wi-Fi in my home was a five-minute job. Pairing with my iPhone was also only a few minutes. Everything works remotely or by operating the pushbuttons on the thermostat. I find no basis for criticism of this thermostat.

Rated 4 out of 5 by from Works well! After some rewiring inside the air handler electrical junction box installation was straightforward. Connecting to wifi using an Ipad was almost automatic.This is a good unit and an exceptional value as it has most of the functions found in thermostats that sell for two or three times the price. The manual made programming system settings very easy and the ability to control temp and cycle settings remotely is nicely done.The only feature missing is the ability to cancel 'hold' remotely. It is nice to be able to have your system return the house to comfortable temperatures before returning home after a long absence.What is the difference in features between the 6580 and the 6500?

Tips & FAQs

General Questions

Install Your Thermostat

Q: I am having difficulty removing my old thermostat.
A: Often times, the thermostat will snap off of the wallplate with moderate pressure. Other times, there might be small screws holding the device in place. If you are unable to pull it off, please refer to your thermostat manufacturer's website or manual for removal instructions. NOTE: Do not place your old thermostat in the trash if it contains mercury in a sealed tube. Contact the Thermostat Recycling Corporation at http://www.thermostat-recycle.org/ or 1-800-238-8192 for information on how and where to properly and safely dispose of your old thermostat.
Q: I have additional wires in my wall that were not connected to my old thermostat. Do I need them to install my new thermostat?
A: An extra unused wire in the wall can be used as the C wire for your new thermostat. The extra wire will also need to be connected to the C (common) terminal at the heating and cooling system. This will provide power to your new thermostat. Please refer to the video section for more information.
Q: My metal jumper wire fell out of my new thermostat, which terminals does the jumper need to be connected to on the thermostat wallplate?
A: The jumper wire can easily be replaced connecting it to the "R" and "RC" terminals on your thermostat wallplate. If you are unable to find the factory installed jumper, a short piece of wire can be used in its place. Please refer to step 1.7 in the Quick Start Guide.
Q: What tools or materials are necessary for the installation of my new thermostat?
A: In most cases, the only tools and materials required are a small flat edge screwdriver, #2 phillips screwdriver, your thermostat ID card (located in the box), and your home Wi-Fi Network password.
Q: How do I know if my old thermostat contains mercury?
A: The thermostat will have a glass tube with a silver liquid inside of the tube. Mercury is typically found in older mechanical thermostats like the Honeywell Round T87 and rectangular T8090. NOTE: Do not place your old thermostat in the trash if it contains mercury in a sealed tube. Contact the Thermostat Recycling Corporation at http://www.thermostat-recycle.org/ or 1-800-238-8192 for information on how and where to properly and safely dispose of your old thermostat.
Q: Do the color of the wires correspond to the letters on my new thermostat?
A: There is no code governing wire colors and thermostat connections. The thermostat should be wired by the letters found next to the wire screw terminal block. If you do not know the letter labels, then you can trace the wires back to the air handler/furnace or heat pump/ac unit.  That will allow you to determine the function of each wire at the system and then allow you to attach it to the matching terminal on the thermostat.
Q: What size screwdriver do I need to install my Honeywell thermostat?
A: A small flat edge pocket screwdriver and a No. 2 Phillips screwdriver are recommended.
Q: What is a C wire?
A: The C wire originates from the heating / cooling system and is necessary to complete a 24 volt power circuit which is required to power some thermostats. "C" stands for common and there is no universal color used to designate this type of wire.
Q: I do not have a C wire on my old thermostat.
A: If you do not have a wire connected to a C terminal or one that is labeled C on your old thermostat, there might be an extra wire that is pushed into the wall or wrapped around the wire bundle coming from the wall. Gently pull on the wire bundle to check whether there are any additional wires. If you do not have any additional wires, please refer to the Install Videos for alternative wiring.
Q: Do I need a C wire to install my new thermostat?
A: Yes - the C wire is necessary because it provides power to your new thermostat.
Q: Why do I have to verify that the heating and cooling system door is firmly secured?
A: Most heating and cooling systems have a built in safety switch, which stops power to the heating and cooling system if the door is not secured.
Q: I am not sure whether my new thermostat is wired correctly.
A: Honeywell offers several resources to assist in the wiring of your new thermostat. These resources include: Installation videos, a User Guide and a Quick Start Guide. If you are still unsure if your new thermostat is wired correctly, please contact Honeywell Customer Care at 1-855-733-5465.
Q: My heating and cooling system has a terminal labeled "COM". What is a COM terminal and what do I do with it?
A: A COM terminal is often used as another name for the C terminal and issued to provide power to your thermostat. COM can also refer to a communication circuit and will not provide power to the thermostat. If you have both a C and COM terminal on your heating and cooling system the thermostat should be wired to the C terminal. Please refer to the Quick Start Guide for more information.
Q: What is a cycle rate?
A: A Cycle rate is the maximum number of times a system will run, in an hour, when using 50% of its capacity to maintain a given temperature. For a high efficiency (90%+) gas or oil forced air systems would have a recommended cycle rate of 3. This means the heating system will cycle a maximum of 3 times in an hour.  If it is really cold outside the heating system will be on longer and cycle less, if it is mild outside the heating system will run less (be off longer) and again cycle less. Again, the actual on and off time of the heating system will vary as the load on the heating system varies.
Q: How do I find the password to my router?
A: Check the back or bottom of the router or the operating manual for the password. If you are still unable to find the password contact the router manufacturer.

Connect to Your Wi-Fi Network

Q: I cannot connect to my guest network. What do I need to do?
A: Some wireless routers have advanced features like guest networks. It is recommended that you connect your thermostat to your home network. If you must connect to your guest network, then you will need to contact the router manufacture to assist in unblocking port 443 in the guest network firewall.
Q: Are the MAC ID and MAC CRC case sensitive?
A: No, the MAC ID and MAC CRC are not case sensitive. Upper and lower case characters will work.
Q: Why am I not seeing my Wi-Fi setup page?
A: You are probably connected only to your router, not to your thermostat. Try connecting to the thermostat again.

- OR -

The Wi-Fi thermostat works with the new iOS 6, operating system, however iOS 6 does not work for the initial thermostat installation. Please use a Wi-Fi connected computer, Android tablet or smart phone for the initial installation.
Q: I cannot see my New Thermostat on the list of available networks?
A: On the Thermostat Wi-Fi setup page, click on the rescan button to refresh the network list. This can be done multiple times. If this does not work then power down the thermostat by removing the thermostat from the wall plate and then snapping the thermostat back onto the wallplate in after 4-5 seconds. With your device (laptop or smartphone) reconnect to the "New Thermostat" network and open the Thermostat Wi-Fi Setup page again.

If the wireless network is setup to be a non-broadcasting SSID, the user can enter in the network name at the bottom of the page. Enter the network name in the "Add new network" text box, specify the encryption type and click ADD. The new network will appear at the top of the list. Select it, enter a password (if necessary) and select ‘Join’.
Q: How do I enroll/connect to the thermostat via the Internet?
A: Refer to Step 3 ("Register online for remote access") in the Quick Start Guide.
Q: Why isn’t my thermostat connecting to my Wi-Fi router even though it is very close to the thermostat?
A: Verify that the password entered for the Wi-Fi router is correct.
Q: Is there a way to extend the signal strength?
A: Most standard routers can be set up to be a repeater. You can also purchase and install a Wi-Fi repeater.
Q: What is the range or distance of the Wi-Fi signal in my thermostat?
A: The thermostat works in typical residential and light commercial applications.  The range or distance of the Wi-Fi signal is determined by your router.
Q: My thermostat will not connect to my home Wi-Fi network when I supply the correct password. The thermostat shows "Invalid Password" or "Connection Fail."
A: Honeywell’s Wi-Fi Thermostats are compatible with the following Wi-Fi security standards:
  • OPEN
  • WEP PSK
  • WPA TKIP PSK
  • WPA2 AES PSK
  • WPA2 MIXED PSK
  • WPA AES PSK
  • WPA2 TKIP PSK

Please change your router settings to use one of the supported security settings above. If unsure how to do this, please contact the router manufacturer.
Q: While connecting to Wi-Fi, my model RTH6580WF or TH6320WF thermostat is stuck on the screen that shows "Connection Successful" and "Wait."
A: Please try the following steps to get past the this screen:
  1. Power down the thermostat for 3-5 minutes by removing it from the wall plate or turning power off at the circuit breaker. Then turn the thermostat back on and verify that the "set time" screen is shown. If the "set time" screen is not shown repeat this process for longer period of time.
  2. After repowering, press the "fan" and the "up" arrow at the same time for five seconds. Press "Next" until ISU "39" is displayed, set it to option "0" with the arrow buttons, and press "Done." This will cause the Wi-Fi radio to reset.
  3. Please restart the Wi-Fi enrollment steps from the beginning.
