Your control panel is showing a fault code (the red light above the "X").  The code that it is showing is related to the inverter section.    There is no "auto recovery" from this state.  You can try "brain dead" and "cold starts", but likely will need to be repaired/replaced.  Your Schneider tech must help at this point.
