What does H33 error mean on my Panasonic CU-E24NKUA?

The H33 error in your Panasonic Air Conditioner indicates an unspecified voltage between the indoor and outdoor units. This could be due to wrong models being interconnected, wrong indoor and outdoor unit PCBs being used, or a defective indoor or outdoor unit PCB.
