How To Install A Thermostat - Quick and Easy

There are so many ways to cut energy costs with the expense of energy seemingly rising all the time. A new programmable thermostat is a very effective way to do just that. The best part is you don't have to be a HVAC expert to learn how to install a thermostat.
I give a quick overview in this video by taking my existing thermostat of the wall and re installing it. I had no idea how to do this years back but I had the opportunity learn how to install a thermostat from a friends father because he was in the heating and cooling business.
Hiring a professional will probably cost more than you paid for the thermostat itself. By following the steps in this video you can learn how to install a thermostat as well. Not only can you save money on the install but with a new programmable thermostat you can start saving immediately on your how heating and cooling bills.

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.

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

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

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?

Thank you! That was the easiest video to follow of all the ones I came across this morning.

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

Am enjoying ana my knowledge is growing, thanks

Must you turn the power off first? Yours is the same type thermostat I currently have (non-programmable though), but I am switching to an Emerson. After a furnace cleaning, thermostat appeared to act up, maintain temperature, but readings would remain the same even after desired temp reached. Not sure if he knocked dust in there, it was dusty, but since I bought a new thermostat, I'm going to replace so that when they come out, they don't charge me to change it out. Thanks!

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

In my Fan/Coil system I have Orange wire instead of Yellow wire. What do you suggest I do? Please reply as soon as possible. Thanks.

The Thermostat I want to change is TH5220D1003. In my Fan/Coil system I have Orange wire instead of Yellow wire. What do you suggest I do? Please reply as soon as possible. Thanks.

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?

[cynthiacolbert]

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

[sallyoconnor-dlwp]

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?

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

[kathywalsh]

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?

[tailzzzzz]

I have 6 wires. What do I do? I'm switching from a Honeywell to an Emerson.

[patriciateuton]

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