[@googlreviews7813]

This felt like watching Honeywell commercial rather than review lol, I generally don't trust reviews that are sponsored by reviewed product manufacturers. This unit has an average of 3☆ rating at most stores, 3 out of 5 ain't that good.

[@titusllewelyn]

Thank you. This was the only video on KZbin that showed the thermostat screen while adding a sensor.

[@marciobaeta3184]

A question. Why installing more room sensors if the system cannot control the flow? I really don't understand how the AC can reduce the temperature in only one room. I think you need to have a smart "dumper" control in each room of your house to increase or decrease the flow accordingly in each room.

[@titusllewelyn]

True. Only dampers can help regulate individual rooms. Wuth this while yoy are comfortanle sleeping another part of the home could be much hotter or colder.

[@colinmcgregor4277]

I totally get the remotes sending info back to the thermostat but what physically controls heating or cooling air from the HVAC to each room?

[@williammuff5485]

math lol... i'm just assuming it wants all of the "senrors" to be the desired temp with some level of variance.

[@dudleydooright]

It only pays attention to the one sensor (that is included) and determines the room temp for wherever you place that. Multiple sensors are only worth it if you spend your evenings in a different room (for example) and want to schedule a variance at a time you enter that next room. Another example would be scheduling the temp for your bedroom, so you don't have to physically adjust the temp before bed every night (more sensors simply allow you to choose the location that will control the temperature). Fairly worthless for most people using a single zone heating/cooling system with one thermostat. Just take 2 seconds and click your button.

[@jarrenwilcox378]

Listen people if you put sensors in rooms you can't control the temp in that room exclusively if each room is not each in zone, in Wich you would have a tsat in that room to begin with because it's a separate zone. All the room sensors do is based off activity make that sensor the master temp setting for that thermostats zone. This doesn't make your two zone system a 6 zone system, it takes the most active area and makes it's temp settings what the zone is heated or cooled to.

[@jasonmorris7657]

thank you. becaase they definitely were not explaining how the heat shuts off in one room and continues heating up another room.

[@archer102356]

Don't get the T-9 if you have a heat pump with electric strip heaters for AUX heat. It doesn't have any heat strip delay option other than adaptive recover which is inefficient in colder climates. If you want the ability to delay heat strips and allow the heat pump to bring the temperature up look at other options. Many much cheaper thermostats have this basic feature. Best to just set temperature to the desired temperature and not have any setback with this thermostat otherwise expensive heat strips will be kicking on.

[@lloydc3206]

There is a T10 that’s exactly the same as the T9 but includes far more features including aux delays and lockout for heat pumps. The T10 is geared towards professional installs though. For any honeywell home series thermostat you want the “pro series” and not the off the shelf version like the T9. You have to order the pro series from amazon or have a contractor install it.

[@dc5duben96]

thanks for info, excatly the answer i was looking for!

[@sunburn72]

How does the T9 with room sensors cool or heat a room if you only have a single unit and vents are not automatically being controlled to open or close?

[@Bobsnarls]

It’s only meant to report various room temps so the thermostat unit can find an average temp to set the main central hvac. Or you can set it manually. Or you can spend a few thousand to install VAVs in each room. All up to you.

[@Gw2Zoke]

it doesn’t seem to run the fan based on these temperature differences to attempt to “average” the temperature in your house This is a pretty pointless feature that’s just going to perpetuate hot spots. What you want is stand deviation calculations, and a way to hook that into your hvacs ability to circulate air instead of running heating or cooling when all your home needs is a mixing instead of more ac or heat.

[@peaceismyshelter]

Is it good for dual zone systems?

[@keepit3719]

What’s the downloadable app for this thermostat

[@spencermarley58]

this thermostat will also integrate with Honeywell Total Connect 2.0 for integrated functionallity to home automation and security control

[@hhova29]

I wonder if this is better than the larger screened WiFi one you reviewed or even the t5? Planning on buying one tomorrow

[@justdissin7340]

Dam to bad he never replied to your msg im wondering the same thing 😂

[@WakeUpAmerican000s]

The T9 is definitely better than the T5 in its feature set. (WiFi, remote sensors, humidity etc.). It costs more than a T5 or T6 too. And the T10 is better than the T9 if you have Indoor Air Quality equipment that you also want to control from the T-stat. (Humidifier, de-humidifier, Air purifier etc. )

[@WatchRob]

I saw you installed this in place of an Ecobee, how do the two compare?

[@AuthenTech]

I've actually kept the T9 up as my daily for now. Ecobee is great too, but I like the clean white design and large panel display. App is fast and responsive. I miss my ecobee analytics, but not a big deal

[@rgruenhaus]

Can I replace my Carrier infinity thermostat with this for my heat pump which was installed in 2007?

[@jackdyson6660]

Just wondering about your slider video Hey Ben just wondering can It do vertical climbs straight up and down

[@AuthenTech]

I think so, but limited weight of course

[@jackdyson6660]

ok awesome :)

[@bridgethugues5919]

Does it work with a steam heat boiler,

[@dsantostv3711]

Yes it does

[@n0diggityn0doubt81]

does it switch between heating and cooling automatically based on temperature set?

[@DavidZvekic]

yes

[@davidangle3885]

How do the algorithms determine when a person is away vs. sleeping?

[@i81fish2]

I use wood heat and it will heat up the thermostat. Does it have a feature to turn on the fan when the actual temp goes above the set temp by like 3 degrees?

[@D2DNYAC]

@i81fish2 No

[@marcprue]

can you provide the instruction you used for your hook-up/setup? i also have a heatpump for A/C and heating, and a gas furnace for heating when colder..

[@PEREZCHOOCH]

I believe you'll need the T10 model as that one has duel fuel functionality.

[@M6_1LE]

Does this work without a remote sensor? The verbiage on this seems to be all around the remote sensors.

[@WakeUpAmerican000s]

Yes. The T9 works fine without any of the remote sensors. You just have a single point temp sensor like any other vanilla thermostat. The sensors are actually nice to have in a larger home, and can help the homeowner "balance" the hot-air ducts if there are consistent wide differences in room temperature. (by "balance the ductwork" I'm referring to using the adjustable baffles installed in the ducts to restrict airflow to a particular room duct that might be close to the furnace (thus getting a LOT of air), in order to send more air to a remote bedroom duct.

[@carlpolk3554]

Does it come with a plate? These seem to not care about leaving a wall full of holes.

[@keningram2781]

What is the main differences between the older Honeywell color Tstat and the T9 besides the additional room sensor ?

[@AuthenTech]

That's a good question. I'm not exactly positive of all the differences, besides like you mentioned, wireless room sensors, geo-fencing, people (motion) detection, smart home integration (IFTTT, Google Assistant, Alexa, Samsung SmartThings)..

[@independent900]

Have you ever tried to pull the thermostat off of the mounting plate to make changes?

[@grasshopp3r-567]

Will this work for electric baseboard heaters

[@555reuben]

No

[@magictrick8833]

They need a “Holiday” schedule. On certain holidays my power price doesn’t rise during certain times.

[@rgruenhaus]

Can I replace my Carrier infinity thermostat with this for my heat pump which was installed in 2007?

[@AuthenTech]

I'm not positive, try contacting their support. My best guess... yes you'd be fine

[@johnsteve7680]

That wasn't a review it was a commercial.

[@D2DNYAC]

😂 😆

[@lucarvian]

My thoughts exactly...should be titled "how to use your T9 "

[@Max86421]

Honeywell Home’s first Matter thermostat coming soon for 2025 costs just $80 🔥🔥

[@bulvie1995]

Good job, keep it up! *Love the reviews!*

[@susanlichtenstein9036]

my T9 went dark does anyone know how to fix it

[@lilgross011]

I’m currently dealing with this right now. Did you find a solution?

[@crsp76691]

How many people can it geo fence. Me and wifes phone or just 1

[@jungleviper]

My background is orange how do you change it

[@WakeUpAmerican000s]

Orange background means that the Heat is actually running. When the call for heat is finished, the background reverts to white. Same thing happens when the air conditioner is running - the T-stat background changes color to Blue.

[@camlife6930]

I want one! 😃

[@bobgurry948]

We have 5 different zones in our home - I expect I would need 5 T9's. . . .Do you know if they all work well together with the phone app?!

[@letsplayfetch6501]

Can this device maintain 77 degrees even when the temperature drops or increases without human interaction?

[@AuthenTech]

Yes, I think so

[@WakeUpAmerican000s]

Let's Play Fetch - yes, the T9 can be set up to automatically switch from Heat Mode to Cool Mode when necessary. (according to the specs. I have a T9, but no air conditioning, so I haven't tested this)

[@cezons8759]

Wow that actually would be pretty helpful to have around!

[@AuthenTech]

For sure!

[@kbpinglia]

I was wondering how smart the new thermostats are. For example our current "digital" thermo, if the inside Temp is 81 and we set the Cooling to 75. The A/C will turn on and remain on until the temperature around the Thermo gets to 75, and then shuts off. But here's where I was wondering the the new Smart Thermo can do. So once the inside temp gets to 75, it'll start up again if the temperature rose to 76. So its always going to turn on/off trying to hit that desired temp. But theres not much difference b/w 75 and 76. I would like for it to stay off and turn back on if the temperature rises to like 78 or 79. Is that something these newer smart models can learn?

[@niuhuskieguy]

Some have a feature where you can select an offset so the system will allow a certain temp difference before coming on again.

[@WakeUpAmerican000s]

The T9 does not let the user program/change the "swing" temperature - that is, how much the actual room temp must vary from the set-point temp before it calls for heat. The Google Nest doesn't let you program this either, but Google Nest does require 1.5 to 2 degrees difference before calling for heat/cool. The T9 is more comfortable than the Nest when using a gas furnace for heat because the T9 will generally call for heat with only a 1-degree swing from the set-point. I've looked at the Lennox iComfort T-stat for a user-programmable swing temp value and it doesn't have that either.

[@slimtimm1]

Dude your manner of speaking is the strangest thing I've ever heard! Great commercial

[@aviatortrucker6198]

So what is the purpose of the sensor? Oh yeah make the coldest room warm while the rest of the house is broiling!

[@WakeUpAmerican000s]

Aviator Trucker - You observe in your post: >>"Oh yeah make the coldest room warm while the rest of the house is broiling!" You're right. If a furnace installer didn't balance your ductwork to eliminate hot or cold spots in the house by using the mechanical baffles to restrict airflow to certain registers, then the remote sensors on a T9, Nest, or Ecobee Smart T-stat can help mitigate the cold room by using the actual temp in the cold room to control the furnace. (which, as you observe, could overheat some other rooms) If the ductwork is properly balanced to restrict air to hot-spots in order to force more air to cooler spots, the "cold room" will never be more than a degree or two different from the main T-stat temp. Then these T-stat sensors can actually make things more comfortable.

[@Ded-Ede]

Too bad no Apple HomeKit support. Major fail. Next!!!!

[@aripalefski2676]

NICE Video

[@BladeAndrade]

You forgot to mention that this product does not support electric base systems

[@iberianlion1459]

There’s no temperature range limit like the T5 and you can’t put your own password, it’s assigned.

[@iberianlion1459]

Update: range limit is operational. New issue: the app doesn’t show the users, therefore you can’t revoke their access.

[@HINDITECH007]

Smart Review

[@AuthenTech]

Thanks!

[@davidgraham5184]

the T9 does not work with Home Kit, Alexa or Google, another bogus review

[@scottweaverphotovideo]

I'd rather just walk over to the thermostat and set it where I want. Then go do something I want to do and not think further.

[@AuthenTech]

You might be surprised how often you'd tweak temps from your phone, it's a nice convenience feature (or vacation trips away from home, etc) - but of course, not for everybody

[@keningram2781]

My GE wifi Thermostat is upstairs and if I'm downstairs I can use my phone to adjust it.
