Electrical components of an advanced air conditioning unit:

 - Starting capacitor

- Service valve in the liquid and suction line

- High pressure switch: trip at 410 psi reset at 300 psi (+ -10)

- Low pressure switch: trip at 25 psi reset at 50 psi (+ -5)

- Timed CLO board - 30s on departure, after that if there is a trip (due to high

pressure, low pressure or thermal protection of the compressor) will only reset

with the power cut and subsequent feedback.
