  1. What thermostat commands does Amazon Alexa support for TCC?

    When using the skill, you need to specify by name which thermostat/sensor to use. There are two ways to define this/these names:
    - Use the name(s) you set up already – these are shown in the TCC app and can be changed on http://mytotalconnectcomfort.com, or
    - Create an Alexa group, like Bedroom or Downstairs, and add the thermostat and/or one or more sensors to the group. More information at http://amzn.to/2965dCE

    Once you know the name or group of your thermostat, you can say the following:

    Alexa, set [group or thermostat name] to X degrees.
    Alexa, raise [group or thermostat name] by X degrees.
    Alexa, lower [group or thermostat name] by X degrees.

    You can also try variations, such as “raise [group or thermostat name] temperature” or “cool [group or thermostat name]”.

  2. How do I integrate with the Amazon Alexa?

  6. Is the Voice service an optional feature?

    Yes it is, when you first update your app, you will receive a pop-up message asking if you would like to enable the Voice feature. Yes = Voice feature ‘on’ No = Voice feature ‘off’ The microphone icon in the upper right will be present in both cases, but will only work if Voice is ‘on’. When Voice is ‘off’, pressing the microphone button will provide instructions on how to turn Voice ‘on’

  7. Can I change the on/off setting of the Voice feature?

    Yes. For iOS phones, you can adjust the on/off setting by navigating to Settings>Microphone>Thermostat. Once there, slide the top toggle from on to off as you like. For Android phones, you will need to delete the app and re-download it. Once re-download is complete, you will receive the initial permissions prompt described in question 1 above. Choose Yes or No as you like to enable or disable the Voice feature.

  8. Are there different ways I can use the Voice feature?

    You can set the Voice functionality to work in one of three ways: 1. Voice ‘Shake to Talk’. Turn this feature on, and you can use the Honeywell app’s Voice listening mode without pressing buttons. With the Total Connect Comfort app open, simply shake the phone and the Voice listening prompt will activate. You can repeat this action multiple times, allowing you to naturally converse with the Voice feature. 2. Voice ‘Open App in Voice Mode’. Turn this setting on, and you can use Siri or Hey Google to open the Honeywell app’s Voice feature. Say ‘Thermostat’ or ‘Open Thermostat’ to your Siri/Hey Google, and the Honeywell app will open with the Voice feature in listening mode. 3. ‘Shake to Talk’ and ‘Open App in Voice Mode’ both on. Want minimal interaction to engage your home comfort? Having both these features turned on will allow you to check home comfort status, change temperatures, check the weather, all through voice commands.

  9. How does Voice work?

    You must first engage the Honeywell app’s Voice feature in one of the ways described above. This will put the Honeywell app’s Voice feature into a listening mode, which you will recognize by an audio ‘’ping’ and a pop up listening visual. From there, the Voice engine was built to engage with you in that way real people talk. Ask questions, give instructions, and the Honeywell app’s Voice feature will respond. A list of phrases which can be used is below, and is also available within the Voice feature’s in-app tutorial.
    If you want to change the temperature:
    "Set to 64 degrees"
    "Set to 77 degrees" (40-90 degrees)
    "Make it 2 degrees warmer"
    "Make it 7 degrees cooler" (1-10 degrees)
    “Make it warmer / cooler”
    “Make it much warmer / cooler”
    “I’m feeling hot / cold”
    For all of these changes, if your thermostat is on a schedule, it will stay at this new temperature (temporary hold) until the next scheduled period begins on the specified day.

    If you want to get weather information:
    "What’s the weather forecast?"
    "What’s the temperature inside / outside?"
    "What’s the humidity inside / outside?"
    "What’s it like inside / outside?"
    “What’s the temperature?”
    “What’s the weather like?”
    Your thermostat must be registered at myTotalConnectcomfort.com as the outdoor temperature/humidity/weather forecast is derived from the Internet. Indoor temperature/humidity as sensed by your thermostat

    If you want to know what you can say to the app for your thermostat:
    "What can I say?"
    You can also press the "What can I say?" button on the App.


    If you want to change the system settings:
    "Switch to heat / cooling"
    "Switch the system to auto"
    "Turn the system off"
    "Turn the emergency heat on"
    These changes require that you use touch on the app screen to confirm that you want to make the change.

    If you want to change the fan settings
    "Turn the fan on"
    "Switch the fan to auto"
    "Follow the fan schedule"
    "Turn the fan circulation on"

    If you want to change the humidity settings
    "Switch humidifier / dehumidifier to auto"
    "Turn humidifier / dehumidifier off"
    "Set humidifier to 35 percent" (10-60 percent)
    "Set dehumidifier to 50 percent" (40-80 percent)

    If you want to say other things:
    "Call Honeywell Customer Service"
    "Switch to the Location Name + Thermostat Name" (E.g. "Switch to the Home Bedroom.")
    If your device has a phone, the app will switch to the phone application and dial the Honeywell Customer Service number.

You can access your other thermostats through the menu on the upper left corner. Android users may notice a set of permissions when you first use the new version of the app. These are auto-generated by Google. They address some of the features you’ve been already using such as the ability to reach out to a contractor near you from the app. As we prepare Total Connect Comfort for future updates, we’ll continue to communicate what this will mean for you.

    In order to register the Gateway you must have the device connected to the internet. If you are receiving a registration failure message, verify you have internet access. The Internet light on the Gateway should be green. If the Internet light is red it is an indication that the Gateway is not connected to the internet. Also verify that the MAC ID and MAC CRC entered from the bottom of the device are entered correctly. Entering the ID numbers incorrectly will result in a registration failure.

  8. I replaced a thermostat in my system and now the zone appears twice in my zone list.

    When replacing a zone on your RedLINK Internet Gateway you first need to reset the Gateway device by holding down the connect button for 10 seconds and then re-connecting the new RedLINK thermostat. This may require assistance from your HVAC contractor.

  9. How can I tell if I have a RedLINK 1.0 or RedLINK 2.0 thermostat?

    The software revision of the thermostat can be found in the equipment status page of the Prestige thermostat. Go to Menu, then Equipment Status and then scroll down to see the Software Revision. Redlink 2.0 thermostats will begin with 02.

  10. The RedLINK Internet Gateway does not show up as a connected device on my Prestige Thermostat.

    When connecting the RedLINK Internet Gateway to Prestige 1.0 and Prestige IAQ 1.0 thermostats the installer will not get validation on the thermostat screen that the RedLINK Internet Gateway has connected if there is a Portable Comfort Control already installed with the thermostat. This also applies to the Wireless Device Manager View Connected Devices screen in which the RedLINK Internet Gateway will not be shown as a connected device. When the Connect button is pressed on the RedLINK Internet Gateway the installer will see the RedLINK LED rapidly flash Green. This is the visual indication to the installer that the RedLINK Internet Gateway has connected to the thermostat (this applies to both Prestige 1.0 thermostats and Wireless FocusPRO thermostats). The customer will then be able to see the thermostat on the My Total Connect Comfort portal.

Wi-Fi Thermostat

  1. What is My Total Connect Comfort?

    My Total Connect Comfort is a web portal for remote access to a Honeywell RedLINK™ enabled or Wi-Fi enabled thermostat.

  2. I do not have a C wire on my old thermostat.

    If you do not have a wire connected to a C terminal or one that is labeled 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 http://wifithermostat.com/installation-videos for alternative wiring.

  3. Do I need a C wire to install my new thermostat?

    Yes - the C wire is necessary because it provides power to your new thermostat.

  4. Why do I have to verify that the heating and cooling system door is firmly secured?

    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.

  5. Do the color of the wires correspond to the letters on my new thermostat?

    There is not code governing color of wires and thermostat connections. The thermostat should be wired by letter 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.

  6. I have additional wires in my wall that were not connected to my old thermostat. Do I need them to install my new thermostat?

    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.

  7. My metal jumper wire fell out of my new thermostat, which terminals does the jumper need to be connected to on the thermostat wallplate?

    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.

  8. My heating and cooling system has a terminal labeled "COM". What is a COM terminal and what do I do with it?

    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.

  9. I am not sure whether my new thermostat is wired correctly.

    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.

  10. I am having difficulty removing my old thermostat.

    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 www.thermostat-recyle.org or 1-800-238-8192 for information on how and where to properly and safely dispose of your old thermostat.

  11. How do I know if my old thermostat contains mercury?

    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 www.thermostat-recyle.org or 1-800-238-8192 for information on how and where to properly and safely dispose of your old thermostat.

  12. What tools or materials are necessary for the installation of my new thermostat?

    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.

  13. Why do I need the lithium battery when I have a C wire?

    The battery maintains the time and date in your thermostat during power outages. It does not provide power to your thermostat.

  14. I do not know if the battery cell is fully inserted in the back of the thermostat.

    The battery should slightly stick out of the battery slot. A correctly inserted battery will extend about halfway out of the battery slot on the thermostat.

  15. What is a cycle rate?

    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.

  16. How do I find the password to my router?

    Check the operating manual or the router for the password. If you are still unable to find the password contact the manufacturer of the router.

  17. Will my thermostat still work if I lose my Wi-Fi connection?

    Yes, the thermostat will operate your heating and/or cooling system with or without Wi-Fi.

  18. Why am I not seeing my Wi-Fi setup page?

    You are probably connected only to your router, not to your thermostat. Try connecting to the thermostat again.

  19. Why isn’t my thermostat connecting to my Wi-Fi router even though it is very close to the thermostat?

    Verify that the password entered for the Wi-Fi router is correct.

  20. What are the MAC ID and MAC CRC for?

    The MAC ID and MAC CRC are the unique identifiers used for registering your new Wi-Fi thermostat.
