Josh, awesome video. I sell these stats up in Canada and I wish more contractors were as comfortable as you jumping into the wifi world. You are helping this movement!! Lol Thanks for posting. Keep the videos coming!!

You are the only one that covered the orange wire and I was having a heck of a problem with it. Thanks

Thx. Guy came by today to put it in & said plate doesn't fit. It was his 3rd one. Before he left I watched ur video & now he knows how to put the plate on.😁

Great video man I was scared to do it myself but did it even had to connect my c wire to the mobo at the furnace thank you for the help!

Thank you for telling us where to find the date code!

My company just got a couple from our distributor. Think I might try one at my house

Thanks for the helpful video! We just had a new Bosch package unit installed on our roof (BRB) and we were informed after install that Bosch had recently informed them that the Nest algorithm doesn't play nice with the Bosch smart features in the unit. They recommended the T10 or an Ecobee. We decided on the T10 since it will allow us to set the cycles per hour down to the recommended (1). Also, the extra smart features on the T10 and Ecobee need to be turned off as well we're being told.

What is your go to honeywell t-stat for heat pump systems with single stage cooling and a oil boiler backup?

I ended up with the T10, love it. However, there are some contradictions between the documentation, and the actual interactive menus within the app! Specifically, the instructions say that the Humidification Window Protection setting provides more protection (ie. lower humidity) at the lower end of the 1-10 scale, while the actual menu and help system in the app, says the opposite. Which is correct?

Thanks for this, I couldn’t find where the date code was the installer password. Much appreciated!

I have a two stage compressor, is there a way to see which stage is running on the thermostat?

Hi, thank you for the video - I have a question about the setup: If I have a 16 year old digital thermostat from Honeywell currently installed and I swap it to a new smart thermostat, do I have to install or change anything on the HVAC system at all (sensor?)?

I have only used Honeywell wifi thermostats in my home. Seems the temperature is more accurate and comfort levels feel better. My favorites are the T9 and T10. Thank you for the great video!

For Bosch heatpump inverters (1.0) should the cycles per hour be 1? I was reading that the control board on the bosch will manage it and on the thermostat it should be set to 1 cycle per hour.

I have a thermostat in my living room which holds the most heat. It’s also right next to my fireplace so whenever I fire up the wood stove it thinks it’s hotter then it is and the heater shuts off. Can I use this to put sensors in other rooms so the heater will run until my rooms are the temperature I wanted then to be at?

Does the T10 have a setting like don't run the heat / ac until it is xx F off from the set temperature instead of starting to run in 0.5F difference? The Ecobee premium has this seeting.

Awesome video Josh, one thing I haven't seen anyone go into depth with is the schedule settings here, I've talked to a few people at the honeywell tech support with no luck, and simply cannot figure out how to stop thermostat from changing the temperature by itself in the middle of the night being on it's factory schedule. I have tried going into geofencing and setting a schedule but cannot figure it out! It turns down to 62 every night and my heater will not kick on so I wake up freezing. Any clues as to why it keeps doing this? Thanks!

Thanks for the video. I’m still on the fence… since the setup for T10 is more involved than say a Nest. I like the idea of taking off a T6 and popping in a T10. But there are so many details in the configuration that I just don’t know much about… those questions just do not come up in Nest set up. Thoughts?

Did you put w for e and drive aux and e together is it dual fuel?

Great video! Where did you get that large wall/cover/trim plate? I'm replacing two horizontal style Honeywell thermostats with T9s, but cannot find that large wall/cover/trim plate anywhere. I'm trying to avoid repainting two walls just for a new thermostat.

very well done Josh, l am searching for information regarding Honeywell Humidistats. I am in Florida so maybe you may not have customers with this issue. When closing up the condo for the season (summer months) my current thermostat is controlled by a Humidistat l have set to turn on when leaving for the season. This, l believe, will not work with the T9 or T10's as it will in effect shut off power to the thermostat thus not allowing the monitoring via the APP on my phone. The thermostat will only come on line when the Humidistat reaches the interior humidity level l have it set for. Typically l set the humidity at 65% and the thermostat to 74F. This results in my maintaining an interior humidity that will not allow molds to form and still have the AC kick in. I do not think either the T9 or T10 will permit me to do the same thing but l think l could control the humidity adequately by just increasing the thermostat temperature. Obviously the thermostat can be set at a higher temperature as no one would be in residence but would still allow humidity to be maintained. I would much appreciate your opinion on this situation as the Tech folks at Honeywell can not seem to understand the difference between a Humidistat and a Humidifier. Many thanks Dave

What is the safest low setting on cool. I bought a home at the installer was adamant it should be locked at 70. 70 cool in Texas ain’t always cool enough. Can I go to 67-68. Any feedback appreciated.

I recently had this Honeywell T10 installed and for some reason I always get “waiting for system”. Not sure what’s going on with it, but sometimes it doesn’t turn on the fan outside.

Great video. When i first set it up it only gave the option to heat not cool. i have a heat pump whats the deal with that

Great Video. Just curious. I just replaced a Trane Thermostat with this T10. Curious it season to run weird cycles .. Been running 7 minutes on and 16/17 off. Today not to hot or sunny. Setting to 73 and outside is 82 or so.

Is it better than nest?

question for you or anyone, this is our second cooling season now on this t-stat, and for some reason, it makes the system run forever. like today here in PA, we just turned on the ac, it was i think 77 or 78 in the room the tstat is in, we have it set to come on a certain time at 75, and drop to 77 like later in the evening to sleep, it has ran for over 3 hours to cool to the 75, never got there. i actually watched it go to 75, then right back to 77, and now its at 76, and we pushed it up to 76 to get it to stop running and it didn't stop. any suggestions what is going on? why when it reached the desired temp it doesn't shut off, so frustrating for a new system, and it just runs all the time, my electric bills in almost $400 per month. thanks

Will this Tstat control dual fuel using the internet temp instead of the hardwired sensor? I don't have the extra pair of wires running to Tstat from outdoor unit to connect a sensor. Will be upgrading from a Vision Pro 8000 set to gas heat full time. If it's necessary I can get my contractor to pull new wires when he helps me with the install, but wanted to avoid it if possible.

I'm getting an American Standard Gold Series (2-stage Heat pump) with a variable speed air handler and the contractor is pushing the poorly rated Nexia XL824 T-Stat that requires a monthly subscription. It seems the T10Pro does everything I need and no monthly subscription. Can you help me make the choice?

Instructions say to push down on the tabs as you guide the wires in the hole. Some older wires are brittle.

Can you purchase multiple sensors for different rooms? And also how does it direct air to different rooms If there isn’t anything inside the vents to close or open and cut off different rooms

Do you have to turn off the furnace at the unit before installing this thermostat? Or do you just turn off the breaker for the furnace?

Hello, will the T10 automatically recognize the Honeywell fresh air system when the wire is plugged into the U1 slot? I was hoping to use a nest thermostat, but it doesn’t support the fresh air system. Thanks

Why does it say "Do not connect W wire" on the lid that snaps over the wires????

Does this T-10 stat have the option to circulate the fan, and is it adjustable in time? thanks.

Hi, great video...thump-up! Help.....my new house have the same thermostat (T10) we set a/c temperature at 78, but it kept going down to 70. It was working fine in the beginning when we moved in the house about 1yr. What should i do? Thanks in advance!

You willing to come down to Smithfield if I throw in some brisket?

Trying to get the thermostat to switch to cooling. It’s in automatic but not turning on AC.

Will this work on older Honeywell with redlink where my old Honeywell only had three wires red white blue wires to 123? I did have a yellow and green stuffed in the wall hole

Where do I get redlink?

How do you get this one to work on duel fuel gas/ heat.

Where did you find the oversized wall plate, and will it work with the T9 thermostat? Thanks!

Any word on a successor to this? (T11?) Can this read outdoor temps from a Weather Underground station?

Josh - I have a question for you. I just had a new Lennox EL18XCV installed in my home. The installer included new T10 thermostats with the unit. I was expecting to get the proprietary iComfort thermostats, but the installer said that the T10 is what they always used. But the installer also seemed to believe the unit was a single stage unit, when in fact the EL18XCV is a variable-capacity inverter compressor. So will the system still operate as a variable system without the iComfort T-stat? Is the T10 able to take advantage of the variable-compressor? Do need to change a setting on the T10?

I have a question about the T-10, I'm looking for a wifi thermostat & add door sensors. Will this T-10 completely shut off the fan & a/c complete when the door is open? When door shuts it's in operation. What thermostat will do this? Thank you

Hi Josh, How does the T10 compare to the Honeywell Vision Pro 8000?

I need to set up with an existing dual fuel system and outdoor sensor. do you know which ISU#'s I need to configure?

Hi there, how would I get to permanent hold? Thanks

It is a Honeywell home product you might want to update.

can i use the t9 if i have a heat pump AND electric furnace ? or do i need the t10 pro as shown in your video ?

Have an issue with the 9000Series. Emergency Heat comes on when there is 1 degree of difference. No way to change it. Looking for replacement, can you set the different degrees like until it hits 40 don't let aux come on? Also I have two unit heat/cool pump. Thanks man.

HI, I'm scouring the internet looking for help setting up my T10 for a Trane XL80. It's high efficiency and 2 stage. Stuff like, cycles per hour, and finish with stage two, and fan runtime after cycle. Have you set one like this yet? I could use some pointers or some direction. Thanks

Just connected my t10 to my Lennox ac and now it’s blowing hot air instead of cooling

I have a dual fuel heat pump, It seems to switch to the backup heat at around 40 degrees, any idea where to change this setting?

Hey i have one of these the power went out and ever since it came back it never came back on i tried to reset the ac breaker but no luck , any ideas?

If I am connecting this with RedLink to the EMI can I just connect power to the thermostat?

The time on my thermostat is wrong, I am logged on to to my wifi. When I try to change the time it says it works off the wifi, am I missing somethimg?

So what’s the lowest temp setting heat/cold? I have a Sensi with lowest setting of50

Does this model do both Redlink and WiFi?

How do you set the humidity to a certain range? Just cant get ours to be below 70% . AC can be at 65 and humidity would still be 70%

Any chance I can email you my Bosch model numbers and you can tell me exactly how to set up my T10? I no longer have much confidence in my original installer.

Where could I find the crc number for this thermostat

I have a conventional gas heat and AC system. How do I tell it that I have two stage heat?It only does one stage>

How do I reset the passcode? Or reset to factory settings?

Help!!! I don’t have a C wire can I use this

I installed my T10 with just the wire holder screwed to the wall. Much cleaner look. No extra plates.

Bueno día quiero saber cómo se instala en un aire an cool normal que solo tengo 3cable por qué el fan cool no tiene más o siones. Pero quiero que la repueta sea en español por favor

My Honeywell T10 started getting "memory error" alarms after 1 year. Now it alarms about once a week and shuts the system down. Honeywell support will only honor the warranty to the installation contractor not the customer. So you will get a new thermostat, but you will still be paying the $$$ service fee. $200+ thermostat for a total of 18 months of use is not very good.

Hi Josh, I had a T5 and was able to lockout the Em heat above 25 degrees in the settings. This way I was using the heatpump and saving on electricity. I bought a T9 and this option is not available on this unit vs the t10. However, I do have the capability to just zero the backup heat on my T9, just like you did on this video on the t10. Does this mean that even if I have the back up heat, it will be completely locked out and I will use just the heat pump? I don't like the blowing of cold air when the heatpump can't get hot air flowing on it's own when temps outside are let's say below 25? but it saves a lot of electricity. I am not sure at what outside temp will my T9 turn on the EM heat if I just leave on. Do you? (i know they use Accuweather to determine the outside temp for the lockout) Should I buy the T10 instead as a home owner just for this feature? I live in TN and we do get some nights that get to the 25s and several on 35 degrees. With the T5 I had it lock out the EM when temps were above 25 degrees and it saved me a ton of money last year. I have a newer heatpump now though and will be installing new windows as well, so my home will be able to keep heat inside longer I hope. ( a goodman 3.5 ton heatpump with air handler under the house.) Anyways, I'd appreciate your input on this. Thanks

It looks crooked on the wall.

Skipped a lot of steps. Like the pass code. You might have covered it later but was not clear. There were some that you skipped where you might as well said “I don’t know what this does. If you don’t, hire a professional.” I thought you were the professional. That is why I watched the vid.

The T-10 and the T-9 are almost exactly the same. One is available in retail stores, and the other is only sold at distributors. They pay less, and they can enter their company name, address, and phone number if something goes wrong. This guy waits until two-plus minutes to mention turning off the power and starts the video after he has removed the old stat... Shame! Nothing on the common wire that some WiFi stats require... Shame! You have given me inspiration!

What non sense was this? All you said was ask a professional. You wasted 20 mins with giving no information of its distinct features like humidifier and ventilation.

Why are you yelling?
