New nest thermostat, non learning, clicks

[Braddschick]

I've installed a nest thermostat, non-learning model, and the interior unit now clicks from time to time. I've installed a nest, learning model, 2 years ago and had no clicking on my other unit. So I know how to install a thermostat.  I've added a pic of the old thermostat wiring. Any ideas? And calling a nest pro is not an answer. Thanks ahead of time.

Do you have the newish Google Nest Thermostat (mirrored)?

If you do then I would try this wiring

White - AUX to W (set as Aux heat)

Yellow - Y to Y

Green - G to G

Red - O to */OB

Red - R to R

Blue - C to C

When asked which wires you have in the Google Home app select these.

W/W1, Y/Y1, G/G1, O, R, and C

Awesome thank you! I will try this today!

Thanks for the follow-up! Well it works but I still get the 2-3 clicks before it turns on. Its very strange but at least with your changes I get it to actually work.
