Thermostat compatibility

 Is this compatible with the nest thermostat

Hi,

Looks like it to me.  You'll need to confirm the separate wire labeled "C" is actually connected to the "C" terminal at the other end (HVAC system).  Reason being, you'll want to utilize it for constant power to the nest 'stat.  Otherwise, you will be relying on the nest 'stat internal battery that would need to be periodically re-charged; a bit of a hassle that others have complained about.    Also, the orange wire on the "O" terminal.  It suggests to me that you have a heat pump?

For  Nest Thermostat 2020

I appreciate your help @straitshooter.
