The error code 'PC' is signifying that the outdoor air sensor is detecting the outdoor ambient temperature is too high for the unit to operate.
You'll need to do the following to fix the problem:
- Check the outdoor temperature is within the units operation limits
- Check for any heat sources around the outdoor unit, the unit must not be placed by machinery which gives out heat
- Check the outdoor unit has good air flow, any blockages will overheat the unit
- Check the sensors are not damaged.
