- How to change a Honeywell thermostat and install wiring on a new Trane - Honeywell home thermostat. It's easy to replace a thermostat yourself. The blue wire typically goes into the "C" terminal. If no "C", the wire could be attached to a "B" terminal. But read the installation instruction first.
If you decide to follow this video, please do it at your own risk. - แนวปฏิบัติและการใช้ชีวิต
Excellent. Simple. Straight to the point. No fluff.
I wish you did a video on everything I have to change.
Of courrrrse I find the perfect video with the perfect teacher with my exact old thermostat and the one I wanted to replace it with, but I have seven wires, not five 😢😢😢😢😢
I did not need to replace my thermostat, but I couldn't figure out how to get the cover off to change the batteries. This video was perfect for removing the faceplate! New batteries installed!!!
Glad it helped!
Crystal clear - Great clip
Thanks for sharing

Many thanks!
THE BEST instruction video I have seen! the instructions were clear and very easy to follow. OH! and thank you for the VERY helpful hints on taking a picture of the previous set-up AND the importance of spreading the wires ("like spider legs") to avoid a very unpleasant (and costly) situation! And NOW we have heat!! ("I did that!")
P.S. I feel SO powerful!! GRRRRR! 💪💪(Come at me , Bro!") 😂🤣😂
Great to hear it!
You are such a great teacher! You mentioned so many things I wouldn’t have known! You answered all the questions I had and now I feel comfortable trying it myself!
Glad it was helpful!
Wow wow Straight to point , quick and clear . God bless you bro
Thanks for watching!
Thank you brother!. Straight to the point.
Thanks for watching!
Thank you! You teach well.
Glad it was helpful!
Bravo! excellent explanation. Ty
Glad it was helpful!
I shorted out my transformer by connecting the blue wire to "B". In the old thermostat it was connected to "C". Since Blue wire was connected to "C" (common) in old thermostat, this means it was the return leg of 24V that is supplying power to the thermostat. It's the same on your old one since yours did not have any batteries. You can see on your old one were it is labeled "C is optional with batteries". On the new one the batteries supply the power to the thermostat and there is no "C". Connecting the blue wire to "B" on the new one will short the transformer as "B" is the terminal for the reversing valve for heat pump heat mode.
Yes, if you have a heat pump, the B or O terminals are for the reversing valve. And it's probably best to let a technician handle this job.
In my case, it's a regular A/C system, and the B terminal is for the common wire. My thermostat works with or without batteries, and nothing is shorted.
THANKS SO MUCH!!!
Thanks for watching!
And how would I change the batteries on the new style thermostat?
I have separate thermostats for each floor in the house. If I take the wires out of the one in the basement, will it be safe to leave or do I need to secure the wires somehow? I’m tired of the other people in my house putting the heat on in the basement and forgetting to shut it off making the whole house overheated. I need to somehow prevent the basement thermostat from being turned on but it’s not possible to put a lock box on it.
You can just unscrew one (probably Red) wire from the R terminal and apply some electrical tape to it to prevent accidental contact.
Good video, but do not connect the "C" (blue) wire to the "B" terminal. In his case, he has a conventional single-stage heat/cool system so it did not impact anything. On a heat pump system, this will short out the system. If you have a "C" wire and no "C" terminal, tape it off and do not use it. The old thermostat used the "C" wire to power the thermostat. The new thermostat uses batteries to power the thermostat so does not need a "C" wire.
Thank you!
So the blue goes on the b on thermostat correct?
My blue wire is on the yellow terminal and the yellow wire is not connected to anything?
Yes you don’t connect blue and most can operate on Batteries
Thanks bro I am about to do my hvac test.
Good luck!
@Your-Self thanks I passed with flying colors.
My old wiring has jumper wire connected to RC and RH. I don’t see it on the new on. Do I still need it?
The new thermostat may have a small metal bridge between RC and RH. If not, you'll need a regular wire to connect them to have AC and a Heater available.
My Honeywell TH8321R1001 is short cycling. When I looked at the wiring the red wire is not inserted in the terminal. Instead it's wrapped around the opening to the R and RC terminal. Could this be the cause of the short cycling?
Probably not. But it's better to install the wire correctly.
Try removing the air filter at your furnace/air handler. If it stops short cycling, replace the filter. If the filter is new, you may need a less-restrictive filter. If you have air returns in each room, check those filters as well.
My electric air conditioner is running continuously even when the indoor temperature is cooler than the desired temperature. The electric heater doesn't do this though. It stops once the house gets to my desired warmth Both the air conditioner and heater are connected to the same thermostat though. Do you think this is a thermostat issue or a system issue ?
Did you ever figure it out mine does the same
The system is trying to lower the humidity level to your humidity setting in the thermostat @@xXsatx210Xx
🙏🙏🙏
If you don't have a "C" terminal available, sometimes, the "B" terminal can be used for the "common blue" wire. But please, read the installation instructions for your particular thermostat model first.

Why my contractor plunger won’t pull in when I use heat please
If the contactor doesn't pull in at all, a low-voltage wire could be damaged, or you have bad batteries.
If the contactor pulls in slightly, there could be a bug that crawled inside preventing good contact.
PS. I'm assuming you have a heat pump, not an AC with an electrical heater.
Why is the blue wire on your c?
Cause most common wires are blue.
I can't figure out how to change the day of the week on my TH8321U1006 Honeywell thermostat..Can anyone help?
The day of the week is set automatically when you adjust the year, month, and date.
Do you know how to do that? It's kinda complicated through advanced functions.
