Notes on the Variable Operation :
In the event of a power failure, the selected capacity step will be memorized and retained when power is restored.
This function operates only in Dry, Cool, Heat, and Auto modes.
Power Chill, Power Full, Dew Clean, and Fan Mode operations cannot be used together with the Variable function. Priority
will be given to the last selected function.
If the user removes the battery and reinserts it while using the Variable function, the variable feature is turned off on the
remote. The user will need to restart the Variable operation and select the desired capacity step again.
For the safety and reliability of the AC, the Variable function may not work in lower and higher outdoor ambient conditions.
It is recommended that the user does not turn off the operation lamp and timer lamp LEDs (using the Brightness control
function). Otherwise, the user will not be notified in case they select the wrong step in accordance with the heat load
condition.
If the user selects a capacity step that is not in accordance with the room heat load conditions, this function will notify the
user to change the capacity step, as defined below:
After 30 minutes of the machine working, the Operation Lamp (Green) and Timer Lamp (Orange) will blink for about 30
seconds to indicate to the user that they should change the capacity step.
If the user does not change the capacity step, the next judgment will be taken after the next 15 minutes of machine
working. Until the user changes the capacity step, the Operation Lamp (Green) and Timer Lamp (Orange) will blink for
about 30 seconds to remind the user to change the capacity step.
In the event of a power failure during the above judgment, the timing will restart from zero once power is restored.
Green & Orange LED blinking for about 30 seconds.
