The BEST explanation of a Honeywell thermostat install I've seen! I just purchased a T6 zwave Honeywell pro series thermostat and your video helped my install tremendously. Many thanks for a very detailed video
You're the only one that covered all my questions. Great video .
Thank you so much for this video. I was upgrading from a very old thermostat to this model, and your explanations clarified everything!
Thanks for this... had a A/C no compressor start problem after doing a breaker identification exercise. Found my yellow line not continuous to the compressor. Traced that back to a failsafe connection on the condensate pump. If the pump stopped it would shut down the compressors. That pump was plugged into an outlet we couldn't identify. Once power was restored to that the compressor started. Your description of how the wiring works gave me a much better handle on how to track it down. Thank you again!
Excellent, exactly what I needed versus installation instructions which left many questions unanswered. Honeywell owes you at AC Service Tech bigtime!
Agree, very informative.
Excellent video and instrucciones!! The Best I've sen so far!!! Keep them coming brother
Thank you so much for making this video . A much needed updated on all the newer thermostat , which everyone wants now.
Thanks a lot Charlie!
Very timely; I ended up with an Ecobee installation; however, you should know I have followed your channel for over 3 years; my home system which is 3 years old and installed by a reputable HVAC company because I was away from the area and my wife needed AC during a heat wave.
Bottom line, the Bryant thermostat went blank; I followed one of your diagnostic instruction videos, and located a wire short in the condenser, tested all components and wires, and kept telling my wife I thought it was the thermostat!
Since the unit is under warranty, the HVAC installer diagnosed and replaced the thermostat (with Ecobee).
BTW, the 3amp little popper is a must with this type of diagnostic workflow.
Thank you.
Thanks Pedro!
Excellent explanation of each wire's function - functionality of each wire location (more specifically). Great information!
Thanks for watching our video!
This was great! Thumbs up. Fantastic instructions for a complete newbie DIY'er.
I just took a T2 back to the store thinking it was broken! Your explanation of each wire is very helpful! The instructions in the box are worthless! Thanks!
THANK YOU SO MUCH ❤ You saved me so much money and a migraine 😅
Many BLESSINGS TO YOU!!!!
Excellent! Thanks for the tutorial. Very relevant.
Thanks a lot Jonathan!
I bought a Royalton 2-stage furnace. I gave it to my friend and it is 60 miles away from here, I have never been able to make this Honeywell thermostat work, I bought one before and we gave up on it as we did in this case again. The furnace says not to hook up the C wire but it doesn't talk about two-stage thermostat connections. I don't know what to switch position is I will check it when I go back to town but we could not get it to operate heat at all. And I contacted them but it was Friday so it's the weekend now and I appreciate the knowledge that I got from this video. I'll get back to you and tell you my progress and we'll check out your wiring charts. I checked out your thermostat wiring charts and it doesn't talk about two-stage furnaces. I would prefer the old-fashioned double Mercury thermostat without all the confusion, and they're not on offer at Lowe's Home Depot.
Thank you for the help!!! Your instructions were great
Definitely the most informative video producer of all time! Thank you for what and how you do it!!
Glad it was helpful, thank you for watching!
Thank You so much for your detailed info, You really helped me tremendously!!
Excellent video! Many thanks.
Another great, informative video. Thanks again 👍
Thanks a lot Paul!!
Excellent video, great information on what each wire controls. Thank you AC Service Tech!
Thanks for watching!
I’ve come to like the new Honeywell/Resideo stats. The set up programming is not intuitive, but they are pretty flexible in what they can do
Great explanation
So nice explained thanks
Good explain sir
Great info. Craig. Thank you.
Thanks a lot Brian!
Excelente tutorial
Best explanation yet! I found that the installer incorrectly wired my T6 so it never ran properly from day one. They had the white wire on "W" which is wrong for a heat pump system. I replaced it with an RTH8500 unit and I also have noticed that the outside unit runs much quieter now. I'm not sure why but the T6 was the date code that is supposed to be defective.
Nice presentation 👍👍
Thanks Roy!
This is great content thank you
Thanks William!
Thanks for this useful video. In case of water source heat pump, do we need W terminal to be wired?
Great video. Im looking to upgrade to a wifi thermostat for my heat pump and this video will definitely help. I just need to figure out where to connect my unconnected c wire in the pump unit .
This was a Very Helpful video that allowed me to install our new thermostat with confidence. And... IT WORKED ! There were only two wires (black and white) and the instructions were Not Clear, but this video was. R & C is all we needed. Thank You.
Do you have a recommendation of how to connect the new smart thermostat to a panel that previously used an EIM?
Thank yo for the knowledge
Do you have a video that covers using a wall mounted IR thermostat like a Flair puck style for a mini split?
Thank God for this video. I just moved into a brand new build and the idiots didn't wire in the G wire 😭 it's 27°c in my room right now
Nice video. thank you for taking the time to make it and explain this in detail. I'm hoping you and or knowledgeable others would be willing to comment to my question, please.
I am having installed, right now, an Amana 2 stage furnace w variable speed blower AMVC960804C and a inverter driven Heat Pump, Amana AVZC200481, with two Honeywell TH6320WF2003 ( a T6 Pro model; I have a 2 zone system) with a New Zone First zone board. The thermostats are wired to what the Honeywell Tstat manual terms a 1H/1C System w 1 transformer for a "conventional" system. This is the most basic wiring in the manual. In the manual are another set of wiring diagrams for "Heat Pump" systems.
Am I missing something? Shouldn't my themostat be wired for a Heat Pump System, possibly a 2H/2C or 3H/2C? If left the way it is, is the furnace going to be able to have the two stages act independently? And is the Heat Pump going to act as variable speed or will it act as just a single speed? Which configuration should it be wired for? Given that furnace is 2 stage, seems like 2H should be applicable, or should it be 3H since there is also the Heat Pump? Given that the Heat Pump is inverter driven what #C should be the configuration? If it's left as 1, will it only behave like a single speed?
I've pointed out the wiring diag in the manual to the tech who is wrapping up the HPump install now and expressed my concerns. He doesn't seem familiar with this thermostat and is going to defer to someone else later as we go over Tstat operation. I'm not too hopeful that there is going to be a acceptable explanation, but am keeping an open mind, or trying to. Thanks for any input.
Hello!
They recently installed a new AC Rheem both inside/out units with a T1 Pro Thermostat (TH1110D2009) , however the AC runs for only about 6 minutes then turns off. It then takes close to 1 hour before running another 6 minutes…
I saw another video about adjusting the cycle rate on the thermostat… Please let me know if this will fix my issue and how can I do it on this new thermostat.
Thanks!
ty for ur educational video
Glad to help wahid!
They did me in on on their T6 issues. I like Pro1 now.
God I replaced soooo many t6's on call backs lol
Hi. My aux and e have a jumper in between them. Do I need to set this new thermostat up the same way?
I just got a lesson in thermostats by a guy that sounds like shoresy. Hell yeah
4:24 in my old thermostat, I have a wire jumper from u1 to r and a staple jumper from r to rc . The main red line coming from wall goes into rc . Do I need to keep these jumpers or will the t9 take care of it automatically? I have a fresh air intake (I believe that is u1) thanks
I have a Goodman 5tn, 2 stage heatpump package for my house. Everything is in the unit that is outside except of course the thermostat. I have a Honeywell Pro Series model number TH6220WF2006 thermostat.
The outside unit also has a 15kw heatstrip. Do you have any videos showing how to wire this unit specifically?
Thanks for posting this
2:26
Is the 12 ftlb torque for the 3 bolts on top enough? It seems a little too loose considering its for the front strut/shock
on my old thermostat I had a wire in the W2 slot where do I put it? I have a regular air condition and heating combination furnace?
Gracias
Just bought one of these Honeywell home t3 thermostats, I have a 4-wire electrical AC heater in my home, seems pretty basic, I hooked up yellow to Y green to G red to R and white to W Gray. Turn on the unit blows hot air. So I switched the white wire to W2 aux still blows hot air. What am I doing wrong.
which terminals for only HEAT
Any idea why my fan won't turn on unless I do it manually?
Auto function won't work.
Great video by the way!
This helped me out so much. I just bought a house and there are only 4 wires with this unit and they used the blue wire for the Y. I think this gives me a way to get a C Wire and keep the other 4 connected.
If i have a honeywell r7284 connected to this controller with a 2 wire configure to an oil furnace, can i run a third wire to the G on the thermostat to somewhere on the envirocom to allow me to run the fan separately from the furnace so i can recirculate the air?
I know it's been a long time since posting, but I have a heat pump. Got everything hooked up fine, but my aux heat and emergency heat are the same. I previously had the TH3210 thermos and they were jumped together. I just hooked up the aux, because there isn't enough room for 2 wires in there, do I need to change that?
I've got a electric furnace home, the furnace fan constantly runs whether it's on auto or on. I don't believe I have an outdoor sensor but I have a black and brown wire going into both terminals could this be causing my fan to always run?
The U terminal we see there, that can also be used for a connected dehumidifier right? Say for example, if a client had a heat pump system setup that also included a Santa Fe Compact70 (formerly Ultra Aire 70H) dehumidifier inside the mechanical closet with the air handler, how then would we go about wiring it up to the thermostat?
Hi please help i have heating and air condition HVAC 5 wires red,green,black,white,orange. do i need to switch up the little switch? also the orange wire can i put it on Y socket?
I have the t6 and was having issuss. The system has been working fine but lately when the target temp is reached the ac wont turn off. Air is cold, no freeze ups, condensate line flowing. Figured the thermostat may be bad. Not sure if it matters but i removed the thermostat to check gor any loose wires and jusy happen to notice there is not a wire in the common terminal. Apparenlty never has been. What kjnd of isdud might that cause
I only got 2 wires ones is black n the other is blame one ? For heat only that good or no?...
Hello AC Service Tech LLC, I need some help please.
My old thermostat had the red wire in the RC slot but the RC slot had a wire that was connected to RH which I am guessing that would be my jumper. My question is, on my new T3 where would that red wire go? to the R? or to the RC? Thank you in advance
The W2 wire was not explained. I understand it is for second stage heat on a 2 stage furnace. My question is how/when does the stat call the stage 2 heat? Does it look for a temperature differential (room is at 16C and the stat is set for 20C and recovering from a temp set-back overnight) or does it monitor the time taken to get to the set temp and fires the furnace's stage 2 after a set amount of time?
My old thermostat had a jumper wire in the RC and RH terminals. I don't know where to put it in my new thermostat.
Is there any video to connect my android phone and operate the temperature from my phone?
If I have a R and a RC wire can I use one (the RC) in the C spot and run a jumper from R to RC? I want to install a wifi thermostat without a C wire. I am installing a T-6 pro Honeywell. I have a R, RC, W, Y, G, wires. i have used a jumper from Y to G and and put the G into the C port. The heat side works great, the cooling side turns on but does not blow air at all. Any suggestions?
If i have a t-5 programmable tstat. Wired up the way it supposed to be for a heat pump and i didn’t put any batteries in cause i have a common wire. I have 28v on red but when i plug the thermostat in it does not power up. Is this a bad thermostat
I was given a T6 pro brand new and want to install it, but I'm confused about where to put the wires from my current thermostat.
So, my current thermostat wiring is set up as follows.
White wire - W
Blue wire - Y
Green wire - G
Red wire - Rc
Then, there is a jumper from RC terminal to RH terminal. I'm not sure where to put the red wire on the new T6 which also has the jumper wire.
Any help would be great.
Thanks.
Can this work on a 240 volt system
Excellent instruction. I have a Amana 2 stage 3/1/2 ton heat pump 1 1/2 years old with a T6 Pro thermostat. I have had the thermostat replaced once because it did not turn off the unit when set temp was met. The unit normally got out of Recovery stage within 30-40 minutes going from cool 77 to 74 at night. Even though the set temp was met the unit runs for hours? The replacement is also a T6 Pro which I have noticed is NOT cutting off unit at night and runs for hours. AC company says is normal! I know it is not but should cut off within 3-5 minutes after set temp is met. The wiring is correct at thermostat (not opening outside unit). I have purchased a T5 Smart thermostat to replace the T6 but feel it is a unit problem so a waste of money. Can you address this issue for me? Thanks
I am having the same issue with my Honeywell T6 not turning off when setpoint is met in heating mode. Runs constantly
I have a two stage radiant tube heater with only 3 wires coming out for therm. Just bought a Honeywell rth6360 therm. Which is digital.......... with my 3 wires coming from my heat box ...can i run both stages of heat with this therm. And not use batteries? My instructions on my heater say i need a 24v thermostat. Im lost
I am currently having issues RTH6360 it goes straight to heat mode it isnt activating the reverse valve selenoid even with O/B wire in the O/B slot i am completely preplexed
I recently had my furnace replaced and my thermostat was replaced with the Honeywell T4. Now my compressor (AC Unit) will not stop running even when the thermostat is off. I have to turn off the power to the AC Unit from the power box. The wiring to the thermostat is all correct as stated in your video. I need help can you tell me what may be the problem. Now the company wants me to pay a thousand dollars for them to run more thermostat wire because my wire is bad they say. I don't it is the wire. Can you help?
Great video but it still left me questions. I have a Honeywell T6 Pro with the external temperature sensor which supports dual fuel. I have a single stage heat pump and gas boiler. So I configured the temperature change (turn off the heat pump, turn on the boiler) to 40 deg F. It seems obvious that I setup for dual power supplies (Rh and Rc) and control the boiler via the W (heat) wire. But what happens to Aux/E? Are they in effect disabled? Or is the thermostat smart enough to know that when the temperature difference is above a couple of degrees that it needs to call for heat via the W wire?
You can look up the model thermostat and verify that it is in fact for dual fuel and the settings will allow you to set this up. There should be a differential that you can set. We usually set this for 10-15 degrees or so because we don't want it shifting back and forth.
@@acservicetechchannel The differential setting is called "Droop," and it's available on the T6 thermostat, but not the T5. I've read in different places that the Droop threshold will trigger the aux heat anytime the indoor temp is lower than the programmed temp by the determined number of degrees, but I've also read that it will only trigger if it drops below the threshold *after a heating call* from the thermostat, while the heat pump is supposed to be running. I'm not sure which is true.
So in this diagram, you have separate and Aux and E wires tied together at the furnace, so essentially they're jumped together and they do the same thing. In my setup, I have a heat pump on a T5 Wifi thermostat with an R and W back to TT on a gas boiler for backup. I've tried terminating the boiler W wire at E and at AUX, but as far as I can tell, there's no difference. Both terminals activate when the thermostat is calling for more than 2-3º of extra heat, and both activate when I turn on Emergency Heat manually. What gives? I guess I need a call to Honeywell.
For a radiant building pipe system with 3 wires, where should the terminals go R, O/B and W?
What is the W2 is for? Mine is Honeywell and it has a wire to the W2. Thanks
Hello there,
I have this thermostat and i have a question, i got new furnace, when i turn a A/C on, the fun turns on not A/C, is it bad condition in furnace??
Honeywell always made my system run all the time. Changed to a WR/Emerson and it’s running normal. I used to think all thermostats were the same but nope!
You didn't wire it correctly. How is that honeywells fault? Seriously.
How I now whish thermostat I need for my HVAC ?????
Sir, please explain about checking the refrigerator inverter compressor, sometimes it is difficult to distinguish the damage between the PCB and the refrigerator inverter compressor
You can always ohm out the inverter compressor, thanks and we will have a new minisplit book coming out soon at the end of the year that discusses that, thanks!
so what about a two stage gas valve, w2 second stage ?
I’ve like the T6 model but the WiFi ones I’ve had burn out ALOT!! Has anyone else had these issues? Nice video Craig!
I know it's been a while since your post but came across an HVAC video concerning your problem . Apparently Honeywell had an issue with some of these thermostats . If you look at the back of your thermostat an on the red label you'll see the model number. Right after that should be a 4 digit number. The problem thermostats have a code between 1917 through 1940 per that video. I'm betting your problem thermostats fell between that range. Best of luck.
The T2 is supposed to work for 750mV heating systems. The thermocouple is the only power source. What are the connections for this two wire system?
I have the same thermostat, and for some reason the fan-on mode does not work. Even though the fan works normally in heating mode.
Hi, I have the old Honeywell control, my white wire is connecting to the port "E" in the old board, but I didn't find the E in the Amazon thermostat, could you tell me which port in the Amazon control I should connect? Many thanks.
Not sure what you mean by amazon thermostat, that could be anything. If it doesnt have an E function then you dont have an emergency heat function in that thermostat, thanks!
Thank you. This video helped me install our new T5 thermostat. Honeywell’s direction was not as comprehensive.
You're welcome!
@@acservicetechchannelCan you please help me sir? I just installed a Honeywell T5 smart thermostat tonight and can't get it to power up after I turned the power back on at the fuse box.
can i email you a picture of my old wired thermostat and find out where those wires go on the T4 ?
What does the brown go to
Great information! You could also change the title of this to include the Amazon thermostat and you would get a lot of additional views.
Tom
Do you have the Amazon stat ? ?
My pro tech stat fried so I am looking t that stat to replace old one. Static power fried the display.
Hello , My air conditioner guy , removed the back of my thermostat. and said this is the problem , and changed it to heat pump . Our electric bill has tripled !!! I took the back off and see a HP switch . is this what he changed and may I switch it , Thank you T
The numbers are too small for our Senior Comunity Pls advice on bigger diaplay as a Pro 7 tstat
All of the wires are connected and my system is not turning on. Do you know what can be wrong? It was working and they were going to install the google thermostat but we decided to keep the Honeywell. After the reinstallation of the Honeywell the ac/heat is not turning on.
I'm trying to use a heat pump with no auxilliary strips and a boiler for 'emergency heat' when it gets below 35°, but can't get this t-stat to switch to boiler without the indoor fan continuing to run on the heat pump?
I had this problem too. After several lengthy calls with Honeywell tech support, I discovered most Honeywell thermostats are not capable of handling that setup. The T6 Pro (non-work) shown here is the only one. In Installer Setup (ISU) there are a couple of settings # 270 and 270 that control whether the thermostat runs the fan in Aux and Emergency heat mode. All other Honeywell thermostats assume you’re using a furnace as backup and always run the fan.
I really like the Honeywell’s for everything else, so I’m probably going to just going to add a separate thermostat for the boiler.
@@litedesign82 My installer located an external circuit board from Jackson Controls, and managed to get it working as it should. I don't remember offhand what the model number of it it.
I have a Honeywell Pro series. Looks like I can just pull it out and plug the T5 in that wire-set.
I did the same but for some reason it runs heat only
My blue not working.i put yellow to c my power up heat working only
Hello, I'm a newbie, and I have a question.
My old thermostat is broken, and the fan keeps running and cannot be turned off, but everything else is fine.
So, I replaced it with a new Honeywell RTH8800WF thermostat.
Currently, there are two sets of wires connected to my thermostat.
I believe one set (Rc, G, Y) is from the AC, and the other set (R, W, C) is from the floor heating.
I connected them to my new thermostat, but it doesn't work.
So, I measured the voltage between all the wires.
Rc, G, and Y are around 26VAC, and R, W, and C are also around 26VAC, but Rc and C have almost 60VAC.
I believe the 60VAC is the problem, so I disconnected the AC connection, and the thermostat works
Can you please help me solve this problem?
How to do a t2
Hello I'm new to your channel. Just switched from honeywell thermostat to Amazon smart thermostat. I have six wires. I believe we have central cooling with a heat pump. We have upstairs and downstairs. Upstairs has 5 wires. Outside we have two ac units it looks like one has copper coils inside. Problem is, when I put the ac on, it blows warm air and it doesn't feel cool. I hooked the wires up like this.
R G Y O/B C
What am I doing wrong??? Upstairs thermostat works well on heat and ac. I'm completely lost. Please help if you can. Great video btw 👌 downstairs with 6 (only 5 are connected. ) wires is having the issue. On the honeywell thermostat before, had the R wire, jumped into the RC slot I guess. Man I don't know. Thank you for your time
God bless.
I just want to override the 65 cooling limit to 60. I cant get it below 65.
I'm almost 100% sure and then I installed mine correctly however even and off mode the key is continually running. Ugh
What is going on of the heat isn't turning off? The red wire is connected to R.
