Page 4: Capacity Control
1. CAPACITY CONTROL Compressor frequency decides by capacity of an indoor unit, operation number of an indoor unit, set temperature, room temperature and outside temperature. 2. AUTO CHANGEOVER OPERATION When the air conditioner is set to the Auto mode by remote controller, operation starts in the optimum mode from among the Heating, Cooling, Dry and Monitoring mode.
Page 5: Heating Operation
When Heating was selected at , the same operation as HEATING OPERATION of page 01-02 is performed. When the compressor was stopped for 6 consecutive minutes by the temperature control function after the Cooling(Auto:Dry) or Heating mode was selected at above, operation is switched to Monitoring and the operation mode is selected again.
