I wanted to stop by and see how I could help.
@Patrick_Caezza, I appreciate the help!
@Bbova1, thanks for reaching back with a clearer pictures. I can see that it is compatible with Nest Thermostats based on the wire arrangement. Do you mind me asking what type of Nest thermostat do you have?
If you have a Nest Learning Thermostat, use this wiring diagram as your guide.
Also, if you have the newer version of the Nest thermostat, it has 6 terminals. You can follow the same terminals based on the wiring diagram above.
Let me know if that helps.
Thanks for getting back with the type of Nest thermostat you have. It's called the Nest Thermostat 2020.
It's compatible with your existing wiring configurations, and jumper wires are no longer needed for Nest thermostats. Referring to the wiring diagram above, you can also follow the same terminals where you will connect the wires: W (white is for heating), C (black is for 24V common), Y (yellow for cooling), R (red for power), O/B (orange for your heat pump) and G (green is for fan). Here's your guide setting up your device.
Please let me know if that helps, or if you have any other questions or concerns.
I just wanted to follow up to see if you still need our help. Please let us know as we would be happy to answer any questions you may have.
I appreciate the help, Mark.
I have one more question. The thermostat above is for 1 of 3 zones. This is the basement zone. I have thermostats on 1st and 2nd flr as well. The other two thermostats only have 4-wires. RH-Red wire (with the RH/RC connector), W-White wire, Y-Yellow wire, G-green wire. What would be the proper install for these?
Thanks for getting back. I'd be happy to take a look into this for you.
Nest thermostats don't require jumper wires. If you have 2 power wires connected to Rh and Rc, the Nest thermostat (mirror finished) won't be compatible, but if there was a jumper wire connected from Rh-Rc, you can follow the same wire setup from your other two thermostats with W (white), Y (yellow), G (green) and R (power).
Please note, a Common wire or a Nest Power Connector may require to deliver constant power and stabilizing the flow of current into the thermostats.
Feel free to let us know if you have more questions in mind.
Got it. Technically, you can still use the current wire set up. Installing a C wire or Nest Power Connector would avoid future power issues or power loss to your thermostats. Check out these references for how they work:
Give us a shout if you have any questions.
I know it has been a while but I wanted to ensure that everything is covered here.
How's your Nest thermostat? Were you able to install it? Let us know if you need more help — we're always here.
It's me again. It looks like you haven't yet installed your Nest thermostat, so I'm going to lock this thread in 24 hours. Please check my responses above for your reference, and if you have any other concerns or questions, please feel free to create a new thread.
