4. FUNCTIONS
4-1 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). Fig. 1 shows about the cooling cycle, and Fig. 2 shows about the
heating cycle.
