I purchased three nest thermostats and I received a free nest power connector. I just had Ontech here to install the power connector to my HVAC system. I have oil heat with forced hot air and different zones (purchased three Nest Thermostats from my local power company). I believe I meet all the requirements to have this thermostat and power connector as per the Google Nest Website. The tech was 30 minutes late for his two hour window, so waited 2.5 hours. He came in and indicated the power connector is not compatible with my system as I had valves. Said no work around. No way to connect the Nest Power Connector.
I would not have purchased this thermostat if I had known that it was not compatible. This should be mentioned somewhere to avoid the time and money spent to install this system.

Hi wjayb,
Sorry to hear about the confusion and frustration you had when you purchased your Nest thermostat. I did want to check in here and see if you were able to get your product returned or to see if you found resolution in any other way. If there's anything I can do for you at this point, let me know.
Thanks,
Jeff

Do you have two completely separate systems or just one system with a zone controller? When I say separate, I mean the heat has its out thermostat and the cooling has its own too.
With a zone controller in play, you need to have a Nest Power Connector for each thermostat and it gets installed between the thermostat and the zone controller for each zone.
Post a picture of your current thermostat wiring and another one of the zone controller wiring.

To include a picture in your message, just click on the little camera icon in the reply window or you can just drag and drop the file into the window.
Not all systems have a nice control board, some are just connected to wires with wire nuts.
What make and model is the forced air system?

Thanks for the pictures, they are perfect.
This is an easy set-up
For each zone, connect the Google Nest Thermostat to these three terminals on the System 2000 Energy Manager device.
White - R to A1
Red - T1 (T2, T3) to W
Any color - A2 to C
This is the manual for your controller and page 13 has the wiring diagrams

Will the power connector work on a split system?
06-07-2022 10:29 AM
I do not understand
White - R to A1
Red - T1 (T2, T3) to W
Any color - A2 to C
Seems like wires go to wo terminals as above?
Which red, Please respond

An electrician called my cooling and heating nest learning thermostat a split system it has the heating from the HVAC and it also has an air handler in my attic. Goggle actually told me the power connector will work on my system.

I do not understand what I need to do.
Please spell it out one step at a time
My system seems to have White to A1
Red to T1 and
Black to A2
What needs to be moved.

It looks like things trailed off a bit here, but I wanted to check in and see if you were able to get this figured out or to see if you still needed some help. If you're still struggling with this, let me know and I'll be happy to work on it with you.
Thanks,

I do not understand
White-R to A1
Do I disconnect the white wire from R and attach to A1? DO I put in a jumper from R to A1
With all of them can you give instructions on what needs to be done.
I had ontech here for $129 and they indicated nothing to do, maybe they should refund my payment and have a better understanding of the job they are going to do, not just waste someone's time.

I do not understand which wires to attach to which terminal. Please let me know and if you can be specific as you see my wiring on a previous picture (have multiple red wires).
