Yes, you want to turn off the connection to the thermostat first before doing any work. Mine is labeled as ‘furnace’ in the breaker box. At 7:46 in my video, I do mention to turn on the thermostat at the breaker box so yes, turn it off before getting started. Take care.
It’s unfortunate that this model of thermostat does not fit into your current set up. Hopefully, you will find another model of thermostat or a set up that will meet your needs. All the best to you.
Hello Kevin, there is no reset button for this thermostat since it is ran by 2 ‘AA’ batteries. I would check your batteries and reinstall those and possibly uninstall and reinstall the unit, making sure your wires are going to the correct letter for your setup. The colored wires may represent something different for your setup. If you have the old thermostat you can refer back to it to see what the previous setup was before you changed it. Since the room temp is not moving on the thermostat when the A/C is on, there is a connection issue or set up issue (You can check your settings - press and hold the ‘Menu’ button for 5 seconds. You will need the guide to review each setting and to make sure they are correct for your home’s A/C unit.) The Quick Installation Guide has troubleshooting suggestions to try, but it seems like something is going on somewhere else in your cooling system.

Hello Norman, for this thermostat, since you have a 2 R-wire set up, you would need to set the R-switch to 2 wires by pushing down on the tab on the UWP mounting system. Then you can insert your RC wire into the Rc-terminal and the Rh wire into the R-terminal. There is no jumper needed for this thermostat. I have linked the installation guide for you to follow, page 5, Step 11. www.honeywellstore.com/store/images/pdf/rth5160-honeywell-thermostat-manual.pdf
Yes, the tabs on either side of the thermostat needs to be pushed down and then you can insert the correct colored wire. The wires will lock in place so the tabs will not pop back up completely. They are easy to see, straight forward install.
This issue sounds like a blower problem. If you changed your thermostat to a new one, make sure your settings are correct for your system. If issue is not resolved, you will need to have someone check for various other issues that cause the blower to stay on. Google: ac blower fan won't turn off for other possible issues or see if you can find helpful videos on RUclips here. You can always turn the blower off from the breaker box until you fix it when you don’t need the A/C to save on costs. The A/C will work as it should even if the blower is constantly staying on so turn off the blower from the breaker box to stop that when you don’t need A/C to turn everything off.

did you shut off electricity to that part of the house / the unit before getting started?

Thank you! Very well explained.
Glad it was helpful! Take care
The wall plate doesn't fit into my electrical box. And why would they make a thermostat that requires batteries?

how do you reset this thermostat? The room temp reading is not moving even when the AC is on.

My current system is with “RH” then with a jumper to “RC”. How do you go by this with HoneyWell thermostat?
