Heat is coming on while in cooling mode

[Jca]

Installed the Google nest thermostat and heat is coming on while in cooling mode.  Not a heat pump.  Original thermostat has W2, G, W, C, Y and RC jumperwd to R.

And how I connected the Nest...

I put my original thermostat back on and everything works as should.

Hey Jca, 

Sorry for the delay but thanks for reaching out and for providing these photos.

Quick question, what did you select as your Heat Source when you installed your Nest Thermostat? Also, could you make sure that  your wires are fully inserted into the terminals? You might also want to check on this link for additional troubleshooting steps: https://goo.gle/33D3Eq4
