    2. Processes and functions 2-1 Room Temperature Control The unit adjusts room temperature by turning the outdoor unit’s compressor ON and OFF. This process is controlled by the thermostat located in the indoor unit. The figures on this and the next page show how each part of the system performs as the room temperature changes and the thermostat activates the compressor to start (thermo ON) or stop (thermo OFF).

    2. Processes and functions 2-13 Electronic Expansion Valve This valve allows very precise and smooth control of the amount of refrigerant flow in the system. Since the valve is operated by a step motor, the control circuits can open or close it in very exact amounts, so the degree of heating or cooling can be changed by just a little, or changed very quickly or slowly.

  • Page 143: Compressor Current Detection Circuit

    2. Processes and functions 2-15 Compressor Current Detection Circuit The Compressor Current Detection Circuit detects the compressor current and, depending on the current range, can stop the compressor motor so it will not be damaged by overcurrent. Overcurrent can be caused by several factors, particularly mechanical seizing of the compressor or liquid backflow.
