I ordered this thermostat to replace a very similar Honeywell model that was over 15 years old and still functioning. I was afraid the old thermostat's relays or electronics might fail at an inopportune time and decided to be proactive. This new model was very easy to install. Wiring was wire-for-wire identical to the old one. So far it is functioning flawlessly. Like the old one, the relays are a little loud but do not disturb me. That might be a drawback if someone is a light sleeper and installing in a bedroom. Programming is easy and straightforward. The thermostat works well with my two-stage Lennox, scroll-compressor air conditioner.

    We have a natural gas furnace with radiant hot water heating in the floors. Will this thermostat work well in this application?

    Asked by: tinadiane
    Hi Tinadiane, thanks for your question. This thermostat is compatible with 24Volt applications, it won't work with 120- 240Volt. We recommend to contact us at 1-800-468-1502, we create a case for you #01855242. With your wiring information, we'll be glad to assist you with the compatibility and any other question you may have. Thank you!

    I currently have the Honeywell RTH6220D model so will the model mount to the previous wiring plug or will it need rewiring? 2. Does this model have an adjustable +/- setting for heating/cooling cycles? I believe it's called "hystersis"

    Asked by: Nick10
    Thanks for reaching out. The Honeywell 7-Day Programmable Touchscreen Thermostat does require the wall plate to be in use with the new thermostat. To answer your second question, this thermostat does not have an adjustable "cycles per hour." For heating cycles per hour, it is to be configured to your HVAC system type. I hope this helps. -Chea

    Hi Phil! The Resideo Honeywell Home 7-Day Programmable Touchscreen Thermostat is compatible with 750 millivolt systems in addition to the following system types: Forced Warm Air, Heat Pump, Hot Water, Steam, Series 20, Cool Only, and Heat Only. We hope this helps!

    Does this have half degrees? Can I set it for 22.5 degrees or does it go up and down by full degrees?

    Asked by: Leanne
    Hi Leanne! Thank you for your question! The Resideo Honeywell Home 7-Day Programmable Thermostat can make temperature adjustments in .5 degree Celsius increments. So for your example, you would be able to set it for 22.5 degrees. We hope this helps!

    Will this thermostat work with out a "C" wire providing power from the furnace?

    Asked by: Diversions
    Hi Diversions! Thanks for reaching out to us. The 7-Day Programmable Touchscreen Thermostat does not require a C-wire. It has a 3-slot AAA battery compartment located in the back. Hope this helps! - Jerry

    I bought this thermostat and it says that I can set filter change reminder but to do that there should be "more" button as I understand, which I do not have. Or maybe there is another way to do it? I do not want to believe that description is misleading.

    Asked by: Sergii
    Hi Sergii! The Honeywell 7-Day Programmable Touchscreen Thermostat does have the ability to set a furnace filter change reminder. You have to set up the reminders during the initial installation of your thermostat. To go back in and verify that you have the filter reminder turned on, please follow these steps: 1) Press and release the “System” key. 2) Press and hold the center blank key for approximately five seconds, until the screen changes. 3) Release the center key when the display on your thermostat reads “0120” on the left and “20” on the right. 4) Press the “Up” arrow key to the right of 0120 to go to Installer Setup Number “0500” which is the setting for the furnace filter reminder. 5) Press the “Up” or “Down” arrow to select your setting for Installer Setup Number “0500”. The options for Installer Setup Option “0500” are the following: 0 - Furnace Filter change reminder is Off; 1 - Approximately 1 month -- based on 10 days of fan run time; 2 - Approximately 3 months -- based on 30 days of fan run time; 3 - Approximately 6 months -- based on 60 days of fan run time; 4 - Approximately 9 months -- based on 90 days of fan run time; 5 - Approximately 1 year -- based on 120 days of fan run time; 6 - Approximately 3 years -- based on 365 days of fan run time. 6) After you select your setting, press the “Done” key to exit the Installer Setup and save your settings. I hope you found this helpful! Thank you.

    is there any way i can calibrate this thermostat? it keeps reading 27 all day and night

    Asked by: ricki
    Hello ricki! Unfortunately, the Honeywell 7-Day Programmable Touchscreen Thermostat does not offer the ability to re-calibrate the temperature. The temperature on the thermostat may be different than other thermostats as this thermostat does take into account the ambient temperature and the radiant temperature. However, if the temperature is not changing and you feel this is incorrect, there may be a bigger issue with the thermostat. Please feel free to contact Honeywell Technical Support at (800) 468-1502 for further assistance with troubleshooting your thermostat. Thank you.

    Hi. There are two contradicting answers in regards to c-wire. Do I need it or not? Since it is battery powered I asumed that not, but could you please clarify as I do not have c-wire. thank you

    Asked by: serg
    Hello serg! The Honeywell 7-Day Programmable Touchscreen thermostat offers the ability to connect a common (C) wire or batteries to power the thermostat. If you have a common (C) wire, then you can absolutely connect the wire to the "C" terminal. If you do not have a common wire, you can use the batteries to power the thermostat. I hope this helps. Thank you.
