If 2 beeps are heard, the operation lamp among the indication lamps has lighted and the timer lamp and standby
lamp blink alternately. In cases where heat pump models are used, this indicates a Cooling/Heating mode mismatch
and, as such, operation in the desired mode cannot be performed.
G: SWING button
(The same beeps will be heard and the same operation lamps will light when auto cooling/heating has been
selected on a model which does not have the auto cooling/heating function.)
H: FILTER lamp
When local operation has been set to disabled because the centralized control mode is established, for instance,
pressing the ON/OFF operation button, MODE button or temperature setting buttons results in the sounding of 5
beeps, and the attempted change in the operation will not be accepted.
