[@mattshults4526]

I had an old Honeywell just as you have pictured, but it only had two wires -- heater only, no fan, no A/C. After watching your video I figured it couldn't be that difficult. I connected the white wire to the W terminal, the black (red? it was dark, color indeterminate, but not white) to the R terminal, and I had functional Heater control on first try. Thanks for posting your video, it was easier then trying to decipher the instructions describing 4 or more wire systems that I could not relate to.

[@johnjacobs3643]

Thanks for the video. Excellent! I have one question. I'm installing this thermostat in my remote off grid vacation cabin for my williams propane stove. I do not have electrical power (I use a generator for lights, etc.), so I was planning on using this thermostat with battery as the primary power. Question: do I just connect to the W (heat) terminal and run that connection on the stove identified as "thermostat"? Thanks for any help.

[@mikesdoityourself]

Williams has a few videos on hooking up a propane heater to your thermostat- in the video, it shows a Williams (2 wire) thermostat application but it talks about your thermostat wire that you have- hopefully that video can help- W connection to your switched heater and R connection to the constant voltage wire (with the R to RC jumper wire removed) is the most common connection for a general thermostat. Good luck! - Mike

Thank you, I got a thermostat like the one you're installing. I wasn't sure about the blue wire going to yellow like my old thermostat.

[@mikesdoityourself]

The blue wire is the "C" common wire which enables continuous power from the red wire- the yellow wire "Y" is for air conditioning. Definitely refer to the wiring manual for the thermostat for more information. Good luck! - Mike

[@richardmilligan1410]

@@mikesdoityourself I moved the blue to C and the compressor didn't come on. I put it back to Y and the compressor worked. New thermostat, reached temp, won't click to tell AC to shut off.

[@mikesdoityourself]

The blue wire being used as a common wire is common in heat pump systems. In this case, the way your old wiring was wired to your old thermostat would be a good place to start for your wiring. Thermostat wiring is truly dependant upon your heating/cooling system. - Mike

[@confucius2616]

Mike I’ve got an older, Mercury type as well and it’s a round Honeywell. Only two wires in back. One is red and the other is green but it’s marked “B”. I do not have air hooked up to this. Strictly a boiler heating system. Pretty obvious where the red goes but does the other one go in “C”?

[@mikesdoityourself]

For a two wire system, it should be red to "r" and white to "w". In a a/c system, the green wire would go to "g" to turn on the blower motor. Since you have a boiler heating system, I would make sure your thermostat is compatible with your system and go by the thermostats instructions for wiring. Good luck! - Mike

[@davidthornton8316]

Hi Mike, How do you snap this model particular thermostat off the mounting plate to change the batteries? Mine feel snapped on very tightly and I'm afraid of breaking the clips. Are there certain sides to apply pressure to to release the clips when pulling off the thermostat? Thanks for a very helpful video!

[@mikesdoityourself]

You can try a flat head screwdriver to push some of the clips if you can get to them- the clips are really tough, so if you pull on a side you should get something to move. Good luck! - Mike

[@ramirogamez1200]

Great nice thanks very helpful you just saved me $100

[@fullofshticks]

Thanks for the video. I just wandering Where did you get the wallplate? It didn't come with my thermostat

[@mikesdoityourself]

The install kit that you see in the video came with all the wall mounts/plates- it could be that this particular thermostat has eliminated the wallplate- it's been a few years since this was purchased. Maybe the wallplate can be purchased separately.?- Good luck with your project! - Mike

[@leodelude43]

Thanks Mike,but do I push both tabs up at bottom or just right side for jumper?

[@mikesdoityourself]

Yes, up for jumper if you have one red wire and the wire goes to the R connection. The tabs get pushed down if you have two red wires and the wires go to R and RC. Good luck!- Mike

[@timprice7936]

Hello sir. When you have the heat pump heating the house in the winter and it needs auxillary heat assistance when the temperatures are real low, will ' aux ht' or 'em ht' show up on the screen when it comes on to assist the heat pump? Thank you for your video.

[@mikesdoityourself]

Yes, when temps are below 40 degrees outside, the heat pump sometimes needs help to maintain the set thermostat temperature. It will turn on the electric resistance heating coils in the air handler. It usually only runs for a short amount of time in this mode. Emergency heat is usually turned on manually and should usually only be used when you have an issue with your heat pump. These two modes will usually incur higher heating bills. Good luck with your project!- Mike

[@naturalnature]

Thank you

[@greenfieldcj]

Awesome - thanks for saving my hurt!!

[@myflowbeats]

What if you have 1 white wire that went to the E. Do I need another one for the W? My previous thermostat only had 1 white wire to E.

[@mikesdoityourself]

On most systems that have backup or emergency heat, there is a brown wire that goes to E terminal. The white wire would go to the W terminal for primary Heat. In your case, I would try the white wire to the W terminal first. You can always change it up if it doesn't work at first. Good luck with your project!- Mike

[@tcspec8980]

Thanks for your reply Mike. They cheapened up the package and now they supply three wall anchors for the NWP. I would have rather paid a few bucks more to get the wall plate and use existing holes. The wall anchors had cheap screws and the heads get torn up easily. Thanks again!

I've had blue wire connected to C line on old thermostat (honeywell),when i replaced it with new I did the same but new thermostat RTH6360 doesn't work without batteries now and I want to fix that.All the rest works fine,Any suggestions? THanks

[@mikesdoityourself]

Most electronic thermostats work on batteries or have batteries for backup in case your power goes out. You would have to find a thermostat that doesn't need batteries for basic functionality. Any decent home improvement store or web search can give you a few ideas to what you are looking for. Good luck! - Mike

[@thlvking]

I have blue wire as well

[@Mrtscrp30]

Ihave a honeywell t6pro programmable with battery backup i want upgrade to the t6pro wifi can i select 2 wire so that i can power my new thermostat instead of the previous connection that use battery backup.? Which i believe is probably set to 1 wire?

[@mikesdoityourself]

If your previous thermostat was wired to run on AC power than it will be easy to hook up the new one to run without battery backup. Battery backup is usually optional on most thermostats. If the wiring is not there, then you may have to run it on battery power. Good luck! - Mike

[@RaecerX]

Hi Mike. I have the yellow, red, green and white wire but I also have a black one. What do I do with that one? I have a gas furnace that is about 5 years old. The thermostat I have is a programmable one. I don’t care for it. I bought the one you have in this video.

[@leodelude43]

Did you push both tabs up ,or just the right side at bottom for jumper?

[@mikesdoityourself]

Both tabs are pushed up- in this system, there is only one red wire so its goes on the up or 1 wire tab. - Mike

[@christyinthecarolinas]

Ok I know nothing about ac units. But I have a heat pump with cool, heat and emergency heat. Will this thermostat work? And would I wire it the same??

This thermostat should work. I would research this thermostat online to make sure. The wiring instructions will be with the thermostat- wiring varies depending upon the system that you have. Good luck! - Mike

[@markjulius2006]

Hello Mike, Great video, by the way. I have a question. I have a 30 year old mercury thermostat that has a brown wire that was connected to a screw labeled "TC". I'm installing the same Honeywell thermostat as in your video. I've labeled all the wires, however, none of the labels have TC on them. I have no idea what to do with the brown wire. Have any suggestions?

[@mikesdoityourself]

In some instances, the brown wire is unused in newer thermostats. It is commonly used for emergency, secondary or backup heating. It may connect to your W-2, Aux, or E terminal on the new thermostat depending on the purpose of it from when it was on the old thermostat and/or what kind of system you have. A functional check after wiring it these specific ways should let you know if you've got it right. Just remember to turn power off between moving wires around. Honeywell has a customer service wiring help line if needed. Good luck!- Mike

hey mike, I have an Orange, Yellow, Blue, Green, White, RH, and RC on my old thermostat. The RH and RC are jumped together. Where would I put the orange and blue on this system, since there looks to be 1 spot for o/b? And, am I supposed to jumper the RH and RC like my old one?

[@mikesdoityourself]

The orange wire is going to be for the heat pump and the blue wire is going to the common wire. I would put orange in the o/b spot and look for a common wire location for the blue wire. I would wire the RH and RC wires separately. I would go by the directions in the thermostat first and if you need to make adjustments, it should be easy enough. If heat or cool doesn't work, you may need to jumper RC and RH. Don't forget to pull the breaker before changing wires. Good luck! - Mike

[@mikesdoityourself]

@@SavDog262 A gas pack is a single unit, electric cooling with gas, propane or oil used for heating. The wiring should be the same, your just controlling different things to make things happen.

[@mikesdoityourself]

@@exoticcar5482 It definitely depends on what kind of system you have as to what your wiring is going to look like.

[@naughtyely18]

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!

[@mikesdoityourself]

Sounds like the company that did the installation has some setting up of the system still to do, or there is warranty work to be done. Cycle rate refers to the maximum number of times a system will run in an hour - most are factory set at 5 to 6 times. This shouldn't need any adjustment, and it won't affect the amount of time your system is actually running. If your system is reaching your set thermostat temperature at the 6 minutes mark, there isn't an issue. Otherwise, you should have the installation company fix the issue.- Mike

I just replaced my thermostat with this same one and we can hear the clicking noise but the heat nor the a/c will power on. Im not sure if I have it wired wrong or what. If you had any ideas it would be greatly appreciated!

[@mikesdoityourself]

Sounds like you may need to recheck your wiring(a short may be occuring) or a control board switch relay is bad or a capacitor is bad. I would go with wiring first- once this is ruled out, I would check the capacitor (s) , after that - the relay or circuit board issue. Hope this helps, Mike.

Mike I wrote you about a week ago asking about the black wire. On the thermostat I have now(totaline) the black wire goes into the c slot. Do I put it in the c slot on this thermostat?

[@mikesdoityourself]

The C or common wire is usually blue or black and is used as a ground for Rh and Rc. Definitely use your old wiring setup for a reference- if there's any stray wires, use the new thermostat wiring instructions - it's all dependant upon your air conditioning or heating set-up in your house/ business/etc. Good luck!

Hey Mike. I have the same wires and entered them as instructed here, but i can only select "Heat" or "Off" on my screen. No cool option. Any advice? Thank you.

[@mikesdoityourself]

Hello David, this is an excerpt from Honeywell troubleshooting- "1. Verify that the wiring was matched correctly from the old thermostat to the new thermostat. If there are not separate wires to R and Rc, these terminals must be connected. On some thermostats this connection is made by a jumper wire connection and on other models this connection is made by a slider switch that has 1-wire and 2-wire settings. The installation guide for your thermostat will show which one you have. 2. Confirm the thermostat has been correctly configured for your system." I am assuming that the thermostat should have the cool function on the selections right out of the box, and as long as all the wires are in the right place- the thermostat may be defective. Good luck! - Mike

[@LuisSanchez-yx6iz]

Hi Mike , i got both wires blue and yellow , if the blue goes to “Y” where I need to put the yellow wire?

[@mikesdoityourself]

Blue goes to yellow if you don't have a yellow wire- otherwise, Yellow wire goes to Y which is for your compressor and Blue goes to common(C) or B(blue) which is for your heat pump. Good luck with your project!- Mike

It's been snowing like crazy hear in Washington with freezing temperatures and my renters aren't happy. My dad left me this house and we really can't afford to keep it. We try and do everything ourselves and my hubby is very handy but we are stumped.

Only problem now is the heat won't run. I have this exact thermostate. Is it possible they messed with the wires and didn't tell me and this is why it's still blowing cold air? Sorry for the long story but I thought it would help explain my issue better. Thank you so much. Also we went and bought a new thermostate that was a bit more simple and it has the O and B connect seperate as many say o/b together. Also other letters that don't match this one for wiring.

"O" connection would be for the reversing valve in a heat pump system (orange wire)- blue wire would be your common wire for heat pumps, this would go to your "B" terminal- I was missing some wires with this install video, so my wiring may be different than yours.

The yellow wire will be for your air conditioner compressor contactor and the orange wire is to operate your reversing valve if you have a heat pump. Both wires may or may not be for your specific situation. It's best to match up the wires to your new thermostat's instruction manual for your specific a/c or heating set-up. I would double check the wiring and operate the thermostat and see if anything doesn't work- then focus the extra wires to that location on the thermostat. Good luck! - Mike

my ac not kicking on. I tried everything, contact on compressor, computer board, no blown fuse, no bad condenser, yet the ac compressor will not kick on. What am I doing or miss?

[@mikesdoityourself]

Circuit breakers may need to be reset, run capacitors may need replacement, bad contactor, and recheck the thermostat wiring- these are a few things that can be checked- Good luck!- Mike

[@lvstodance2008]

I have a brown wire that came loose some how but have red blue white yellow

[@mikesdoityourself]

The brown wire could be a heat pump wire or for emergency heating on some HVAC systems. The other wires should hook up to their respective terminals. Good Luck! - Mike

[@lvstodance2008]

Also have a picture of it

[@aakozanoglu]

I had a B wire. What could it be? I don't think I have a heat pump. My AC is Ruud from 1988.

[@mikesdoityourself]

B wires for Ruuds are usually for the reversing valves for heat pumps that would be wired into the B terminal- I would try that first. Definitely go by the way it was wired up originally and then apply that to the new thermostat. The wiring instructions for the new thermostat should give you some ideas also. I've seen B wire hooked into the C terminal as a 24V common wire (only in certain instances). Good luck with your project!- Mike

[@aakozanoglu]

@@mikesdoityourself I did as the new thermostat's manual instructed, since the replacement when I turn the AC on, the indoor fan comes on but the outside condenser fan and the compressor do not run. I looked for fuses, can't find one in my furnace. I just replaced capacitors in the outside unit, still no outside fan or compressor....

[@thlvking]

I have yellow wire and blue wire

[@mikesdoityourself]

In your case, yellow should go to the "Y" terminal and Blue should go to your "B" terminal- if you don't have a "B" terminal than most likely it will go on the "C" or common terminal. Yellow is for air conditioning and blue is for heat pumps. I would check with your new thermostat wiring manual to verify the connections and if this doesn't help, go by how your old thermostat was wired. Good luck with your project!- Mike

[@WildShortsVideos]

Hey my heater don't pass 73, and I notice the Blue is in C should I change it to Y maybe it help? My coils are clean I don't know why it don't pass 73 and my AC is new

[@mikesdoityourself]

The blue wire is usually for heat pump systems. If there is a B terminal, the blue wire would go there. The blue wire may hook up to the C - common wire terminal or Y terminal- depending on what kind of system you have. I would definitely use the way the old thermostat was wired as a blueprint for wiring the new thermostat. The wiring manual is also a great resource to use. Good luck!- Mike

[@WildShortsVideos]

@@mikesdoityourself i have a orange wire that's not connected to anything. Is that supposed to be like that or no? Or that one goes to OB?

[@mikesdoityourself]

The orange wire is used if you have a heat pump system for reversing valve operation- it would go to the O or O/B terminal depending upon your specific system.- Mike

[@WildShortsVideos]

@@mikesdoityourself I do have a heat pump system, should I put that orange in OB will that fix the problem? Sorry I'm. Bothering but is 36 degree where i am and my central ac unit in my house don't pass 73 degree. Trying figure this. Out

I have a yellow in the Y and a blue in the C 🤔 and my heater don’t turn on 😢 only Ac

[@mikesdoityourself]

Blue wires can connect to the C "common" terminal or the "B" terminal depending on your application. You can check if your common wire is getting 24v from the circuit board or find the wires that lead to the circuit board in your heat pump or furnace and replicate those connections to your thermostat. The wires may be Green to G- fan, white to W -heat, red to R- 24v heater/transformer. Blue to B or C "common". I would use your old thermostat connections as a reference and check your new thermostat wiring instructions for reference also. You never know if some previous person or the HVAC guy changed the wiring in the past (if it's a older home). Good luck with your project! - Mike

[@danigil8050]

What if I hace RC and RH?

[@mikesdoityourself]

It means you have separate transformers to control heating and cooling. RedCool and RedHeat. Always match up your wiring from your old to your new thermostat whenever possible. The new thermostat wiring instructions should be helpful. Good luck! - Mike

[@jasonkite1988]

Carrier heat pump?

[@barryford6795]

Carrier heat pump take pictures of existing heat pump wiring then match it up with the new T stat .then use install instructions to program according to the heat pump T stat you have.

[@barryford6795]

Also on some T STATS there is a switch that says electric or propane be sure to switch one or the other for heating gas furnace or electric heat strips.

What is it exactly you are talking about you have a Carrier your putting in from scratch you run into wiring problem what seems to be happening .

[@michaelhasse2568]

I have this exact thermostat. I have more wires. You put blue wire in yellow, i have a yellow wire- confused. I can't get heat to cut on

[@mikesdoityourself]

Your system may be different, so go by the wiring instructions that apply for your HVAC system. Every application can be different so I can't specifically pinpoint your issue. Blue is normally a common wire, yellow for cooling and white for heating- yours wires/colors may vary. I would hook up the wires that you have to the corresponding slots on the thermostat then research where to put any extra wires you might have. Good luck. - Mike

[@exoticcar5482]

@@mikesdoityourself So are you saying that in your case here blue is NOT a common wire but the heating wire instead? That seems odd because most videos I've watched said that the coloring of wires was standard for each function and that one wire color always mean the same thing for each and every HVAC system. Is that apparently not the case here? And if so, when was this home built?

[@yovanyalonso71]

I have a cuestion? I have a black wire where do I connect that 2 ? Is the the same one you install

[@mikesdoityourself]

@@yovanyalonso71 - blue or black is a common wire- it is unused by some thermostats. Good luck! - Mike

[@carolpawlowski3772]

What if I only have green red and white wires

[@mikesdoityourself]

Green would be for your fan and be wired to G. White would be for heating and wired to W. Red would be for your power and wired to R. Although, I would check your new thermostat manual and wire according to there instructions. Good luck with your project!- Mike

[@kevinpearce3281]

Why does my new stat not shut the fan off. Yes it’s in auto.

[@mikesdoityourself]

It could be a faulty thermostat, wiring not right, or a relay that's stuck/bad. There's some other videos on KZbin that can run through some troubleshooting on when your A/C fan keeps running. Good luck with your troubleshooting!- Mike

[@juliettedeleury]

Quiet

[@jlacey6674]

But I have 2 wires left over......an orange and a blue. Where do I put them? There is no "B" for blue and no "O" for orange;. There's a O/B....surely this doesn't mean that both of them are place in this one input?

[@mikesdoityourself]

B is your 24v AC common wire- it can go to the C terminal. Orange wire is normally for your heat pump changeover valve. This can go to the O/B terminal. This may vary, so I would go with what is listed in your new thermostat wiring manual. Good luck with your project!- Mike

[@urlinmorris1492]

I need help something is wrong I'm getting hot air

[@mikesdoityourself]

Definitely check your wiring - the white and yellow, really all of them- also, check to make sure your thermostat is on cooling and not heating ; if the wiring is correct, then you may have a contactor, compressor, or run capacitor issue. Just isolate one item at a time, this will help pinpoint the problem. Good luck! - Mike

[@danlazar901]

where's the "common wire" connection?!?

[@mikesdoityourself]

Common wire refers to the wire that provides continuous power to your heating or A/C unit, and is usually your red wire, but could be black or some other color. Good luck with your project!- Mike

[@JoseLopez-ti3yg]

Why did you skips over the only part I needed to see 😭 11:25

[@ashatola]

Where is the yellow wire? Where is the Orange wire?

[@mikesdoityourself]

If you have a yellow wire, this would go to the Y spot, this connects to your compressor. If you have a blue wire also, this would connect to your C spot, or common connector. Orange wires are for your heat pump and would connect to the O/B terminal on this thermostat. Since my application shows an older design, my wiring didn't include a yellow or orange wire. Good luck on your project! - Mike

[@ashatola]

@@mikesdoityourself I contacted Honeywell support, a really nice young woman in Mexico who really knew her stuff. She had me move the white wire to W2 and it works great.

@@ashatola awesome, I've had a few people comment that Honeywell has very good support people for their thermostats- every A/C or heating system wiring can be different so the thermostat manufacturer is definitely a great resource. - Mike
