Thisbwas a pretty wack effort at explaining the differences between the letters on the plates.

2:50 wire colors and labeling

How does one fixed if wires are crossed

My Honeywell keeps flashing and switching from off, cool, heat on its own

So I have a Honeywell without a C wire connector. But when I removed the Nest it had a C wire. The other wires are connected properly and the instructions said to tape the C wire. It has batteries also. But it won't come on. What the hellogod did I do wrong? It seems so simple.

I can't get the red wire out.😢

Had 4 wire feed to the thermostat. Connected the blue wire to the "'b" terminal. Made sense to me. Air conditioner fan ran all the time, whether thermostat fan switch was auto or on. Wasn't until I connected blue wire to the "y" terminal, thermostat functioned properly. Counter-intuitive.

I need help My thermostat I got came in and pushed a lot of buttons and now it's worse than it was before. I'm freezing. Can you help me?

Take a picture of the wires w your phone

i NEED HELP. I replaced the thermostat with Honeywell RTH6580. There were 6 wires (Y, G C, O/B, Rc, and Y2) in the old thermostat and I placed the connections to the same letters in the new one. I programmed and then also connected to the Internet. When I turned it COOL, the hot air came on, instead of A/C. The wires were matched perfectly - should I be doing something else?

I have a 4-wire coming out of the wall. Red white blue green. No yellow. The back of my Honeywell rth111b non programmable thermostat does not have a spot listed as C for common. I have central air and a gas furnace. No heat pump no boilers nothing like that. I have red white and green hooked up to their proper locations. Initially my AC was working a few days ago but then it got cold so I went to turn the furnace on and nothing would happen I can't even get the fan to turn on. So I thought I would try changing thermostat from the round Mercury analog to this thermostat now. Not sure where those blue wires supposed to hook up nothing was labeled

I followed instructions. I have heating & air. Is the air conditioner outside suppose to turn on when the heat is on?

Am enjoying ana my knowledge is growing, thanks

mine is honeywell rth111B, it needs battery to operate. So I don't have to connect C wire (blue). correct?

I only have 4 wires

*I love it! **Fastly.Cool** and Warming environment perfectly controlled. Being able to track history temp and humidity takes all the guesswork out of the equation. Had it for two weeks now and it has been flawless!*

What do I do with this black wire it looks like it is hooked into 2 , RC n RH

Thank you for your video. I have the same model. Question #1: Do I have to do basic "Setup function?" Question #2: When the room temperature is matched the setting temperature, the system should stop for a while, right? Question #3: If you turned off the system, it should stop after few minus, right?

Didn't even show how to install it 😕

I have a baseboard oil heat system. The old thermostat had only two wires hooked up. A red wire going to “R” and another wire going to “W”. The Honeywell thermostat has two options for “W”, one is “W” without Aux and “W2” aux. any idea which one to use?

How did you get the red wire in there? I have been fighting it for a solid hour. The R & RC screws are in so tight I can't unscrew them enough to fit the red wire in. All the other screws work just fine

we know it's "HERE"!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I have a quick question I broken my thermostat and took the plate off and trying too put it back on from putting new batteries now the pins are broken off and I dont have time too pick new thermostat so I kept it off so is it safe thanks

I have a blue and black. Help?

What if you have a blue wire but no C space? There is only RC on mine

How did you get the red wire in there? I have been fighting it for a solid hour. The R & RC screws are in so tight I can't unscrew them enough to fit the red wire in. All the other screws work just fine

Thanks! Easy to follow. Greatly appreciated!!!

How do I open The R" terminal?

Why is it that I still get heat coming out of my vents even though the thermostat is set to "off?" I have all four wires attached to their color letters: W,Y,G, and the Red.....I have no common wire....

I’d also recommend to kill power at the breaker beforehand and unplug furnace if accessible

I have a black wire labeled E. Where does that go?

Why won’t anyone explain HOW to connect the wires??? I don’t know what I’m doing. 😡😡😡

Thank you! This really helped!

Well wasted 3 min on this one, onto the next- like to look theses up Before I Get it ..Not listen o to somebody to save $2. and it doesn't save "Alot of $" maybe $10 mo for the heating season..that is if you turn it down to 62 for min 8 hrs..otherwise just a Con game to sell theses Over rated and hype things by H0neywell...We Have 3 Solar Panels and use Elec. 1kw Baseboard Heating and spent ouor $ on Insulated and Windows instead..and a DC HEATING SYSTEM-After 10 yrs? Now Paid off and Its all Free!

nice to know how to take off the cover and put it back on. Helped me immensely.

I have 7 wires. Connected it matching wires from where I took them off. Not blowing cold air. Do I need to wait for it to get cold, or is there a chance I mixed wires & have heat instead of cool?

Can u hook a baseboard heater up to one of these thermostats

My backplate looks completely different that my other one. It does not have the W line to hook up. Labels are E, AUX, Y, G, O, L, R, B, C (optional with batteries) & my old non programmable Honeywell thermostat only uses Y G O W R (with jumper connected R to Rc) any help would be greatly appreciated.

Ridiculous, what's the point? The most unhelpful video ever.

Thank you so much. I looked through a few videos and you said things to the point that I could understand it. I changed my 1st thermostat and saved money in doing so.....

I only have 2 wires and my heat electric?

I only have two wires (red and white)

Hey thank you so much. Your video tutorial really helped me out wiring this thermostat.... success (“ Hey check me out .... Happy Holidays Merry Christmas and have a Happy New Year (“ PeaceLove&GodBless

Thank you.

My blue wire not hook up does it matter ?

I have a gas furnance with 3 wires to thermostate not working. Wht(nuetral), grn 12v. red 12v. not sure of proper wiring to honeywell therm

Don't you have to turn some kind of power off from the braker box?

You have gorgeous eyes! I am in LOVE! :P

*I've had this Thermostat for a few years and is one of the best investments I have made, works great>>>**t.co/NAmF4MJYi5 ** WIFI up time is as good as the internet, simple to install and simple to use, it is compatible with Google Home, just make sure your AC system supports it. the only thing is a little outdated, if you want to monitor energy consumption is not there and must rely on the power company for that. I'm planning on upgrading hopefully their quality has not changed.*

*Great smart thermostat!>>>**t.co/Bh4CIPW6VT** Really well laid out and easy to use, well still offering advanced features. When my parents came to visit they had no trouble using it.*
