  • Page 69: Operation Control

    12. Operation Control 12.1 Basic Function Inverter control, which equipped with a microcomputer in determining the most suitable operation mode as time passes, automatically adjusts output power for maximum comfort always. In order to achieve the suitable operation mode, the microcomputer maintains the set temperature by measuring the temperature of the environment and performing temperature shifting.

  • Page 70: Indoor Fan Motor Operation

     Fan speed control Fan speed selection is prohibited. Fan speed display at remote control is fixed at AUTO. The internal fan speed will set to be SHi + iAUTO-X fan speed shift, it is slightly higher than SHi fan speed initially for maximum 30 minutes to achieve the setting temperature quickly.
