    I'd start with the basics. Manufacturer data should tell you what error 22 might indicate, then check those first. Next I'd check for voltages at the contactor and contactor coils.

    Indeed LP for Circuit 2 and you need to switch off power to the controller to reset this.
    Lack of gas (don't overcharge because there's no receiver) or lack of load or TEV fault.
    It's better to keep your mouth shut and give the impression that you're stupid than to open it and remove all doubt.
