Bad tutorial .. goes two fast w/o explanation of that the Y goes into K and G goes into C.

Thank you brother I needed to change from Celsius to Fahrenheit I pressed the middle button for 3secs and pressed the minus for 0 for Fahrenheit and one for Celsius

I have 2 unused wires. What should I do?

How do I change the priority room it’s set on. It cools my living room and guest bedroom downstairs but in my bedrooms upstairs it’s super hot and barely comes out of the register. Dying of sleeping in the heat when it’s freezing downstairs in the living room.

How do you use the extra wire (in my case blue) as a C wire?

Called Honeywell - these inputs are only valid if you are using a heat pump or some similar set up - these inputs caused my FURNACE to kick on NON STOP in JULY while we had guests and I was at work - NIGHTMARE - I needed "13" amd "1" -

Does one need to unplug the wall power supply that is plugged into your wall outlet before changing and unplugging the old battery?

I have high hopes for this, will be back to give my unbiased review later

The lyric thermostat never displays its network name. it just says "please wait" for hours. please help

I watched your video a couple of times and made sure that I am following instructions and I have a question; After a power failure during a thunderstor, the AC kicked back on and all was good untill we noticed that it is colder in the house than usual while the thermostat was set to 74 degrees, i eventually cranked it up to 77 wich is still cold but 78 is not comfortable. I tried resetting the thermostat to factory settings and still doign the same thing. I downloaded two apps on my phone to read room tempreture and they both read lower by 3 to 4 degrees. My thermostat is Honeywell pro. Hopefully i can get some help,

What do I do if it thinks it’s Tuesday, but today is actually Thursday?

J have a new T9 thermpstat. When I try to add a new sensor I get a message tht says "Can't Enter Enroll Mode". What is wrong?

the number "39" is SKIPPED...not an option -

This channels videos suck. Can we actually go over what everything does not just brush over the simple stuff??

Please explain how to connect the wires

How do i reset if it was accidentally locked?

You mention this is everything about configuring geofence, but you don't address setting up multiple users.

Mine doesn't have cool for some reason. Is there any way to fix it?

I thought this made the installation pretty straight forward! Thanks for the help!

There are no instructions on how to set up and check other devices. It came with 1 extra device but you have to guess how to use it. I would not recommend it. Yes, I have called them 4 times.

This is a great tutorial. I followed it and was able to get my wifi thermostat working without a C wire even after our honeywell tech and electrician could not do so. Thank you!

When I use the app, it has locked me into just 4 periods: wake away home sleep. How can I add more?

Whats the sd slot for?

There is one strange behavior that I have found about the Honeywell 4204. Smoke detector reset. If the smoke detector is cleared manually, say twisting off the smoke from the base for example, then it will not perform a smoke detector reset. It will only perform a smoke detector reset if the smoke is still in alarm when the panel is cleared. Likewise, if you are using a non-smoke fire alarm device, water flow switch for sprinklers, heat detector, or a manual pull station, then it will not do a smoke detector reset on those, except for the Simplex heat detector, it might do a smoke detector reset on a Simplex heat detector. This can be very confusing and can cause you to request a service call when there is no need due to a mistaken belief that the 4204 is not working. I found this out the hard way. Also, fire alarm sirens tied to the 4204 will not be silenced by pressing the 1 key, like you can on the Honeywell vista 20p built in siren circuit. You have to press the security code then 1 to silence a 4204 operated fire alarm siren. Also, strobes hooked to the 4204 will not do audible silence or selective silence. Pressing the code then 1 will turn off the strobe as well. To get around this problem, program the 4204 to turn the strobe on during a duress event. Then press in your distress code and presto! You have audible silence! I found this out on my Honeywell vista 20p system that I installed to protect my family and my dog.

I tapped the temperature and nothing happens?

Thanks.

how long does it take for the thermostat to turn on after reset?

Which would be the recommended setup for a two levels house having two independent heating/ cooling systems (currently one thermostat per level)? It would be nice to see every room of the house on the same thermostat or, at least, on the same app page..

Worked like a charm! Thanks a million!

The worst wifi connectivity process I have ever experienced

Can this adapter be use for non-honeywell thermostats? Nest? My ac unit looks like a rats nest with 4 to 6 wires of each color. I just want to use the thermostat without having to replace the batteries every few days.

If you have other fobs to enroll, what do you do at that point when you say to enroll it? Do I just hit the fob button or do I have to exit and start over the procedure?

How to change from Celsius to Fahrenheit plz

I have downloaded the Resideo app and the Total Connect Comfort app but cannot find a way to activate holiday mode from either

Why would this thermostat not switch to cool mode?

Why don’t I see an options button on my schedule screen?

Can someone help???? My ac was working yesterday then I realized it wasn’t coming on anymore. Cool was flashing and has been flashing since. Sometimes if I cut it off and back on it won’t flash but air still not coming on can anyone help

Is there a way to lock the temperature

Hi, thank you for reaching out. We recommend to verify if the device is connected to a 2.4Ghz network. If your router provides both 2.4 and 5G having the band steering enabled can interfere with the device connection. You can find more information at the following link: www.honeywellhome.com/us/en/support/water-leak-detector/ -Cesar

My leak detector is not staying connected to my wifi

I want to cancel the schedules on damn thing

How do I reset the app on my phone without shutting my phone off and turning it back on

I don't want to create a schedule!

I can not switch mine to heat. It's only going from cool to off. Not heat. What do I do to switch my setting to heat?

What do I do if it says it has already been registered. We are thinking it’s registered to the previous owner of the house. We are the new owners.
