Air conditioning system control (Discovery 1)

The air conditioning control system contains a relay, thermostat, pressure switch and control panel. The pressure switch stops power supply to the compressor clutch when the refrigerant pressure drops below 2 bar and re-energizes when the pressure rises. The same thing happens when the pressure increases above 32 bar, but the clutch is re-engaged after the pressure drops below 26 bar.
