Nest Thermostat
11-29-2021
I have measured 24 vac right on the thermostat between the R terminal and the C terminal yet I keep getting an E 297 error. What is wrong?

This is new with a new cable. If I jumper white to red the heat comes on. I measure 24 vac between red and blue, but I get the e297 error.
