I AM INSTALLING A GOOGLE NEST THERMOSTAT

AND MY ORIGINAL THERMOSTAT HAS A JUMPER BETWEEN R AND RC CONNECTORS. CAN I SIMPLY CONNECT THE WIRE FROM THE R CONNECTOR TO THE NEST AND IGNORE THAT THESE TWO TERMINALS WERE CONNECTED ON THE ORIGINAL THERMOSTAT

ON THE OLD THERMOSTAT, THERE IS A JUMPER FROM R TO RC. IF I INCLUDE RC IN THE COMPATIBILITY CHECK GOOGLE HOME REPORTS THAT MY SYSTEM IS NOT COMPATIBLE. BUT IF I INCLUDE R ONLY, THEN IT IS COMPATIBLE. THE RED WIRE FROM THE FURNACE IS CONNECTED TO THE RC TERMINAL BUT ELECTRICALLY THAT IS THE SAME AS THE R TERMINAL. I SUSPECT THAT I SHOULD NOT REPORT A CONNECTION TO BOTH R AND RC IN THE COMPATIBILITY CHECK.

Unlike most thermostats, Google Nest thermostats do not use jumper wires.
If your current thermostat has jumper wires, do not connect them to your Nest thermostat.
An R wire can go into a Nest Learning Thermostat's Rc or Rh connector.

OK, THE R WIRE ON THE OLD WENT TO THE RC TERMINAL WHICH WAS JUMPERED TO THE R TERMINAL. SO IS IT OKAY FOR ME TO CONNECT THE R WIRE FROM THE FURNACE TO THE R TERMINAL ON THE NEXT?
