Chamber heat in Orca Slicer causes extruder undertemp in start macro

Hello, I would appreciate some help interpreting this error. I have been manually using my chamber heater, but I would like to use RatOS control. I have tried to set up my heater per the docs.

However, using the same model, I toggle chamber temperature and get an overtemp error.

Driver overtemp error was because I had my fan off to look at wires.

Thank you
