Tip: Checking the PI485 DIP switch setting
It can be checked whether the indoor unit address and the DIP switch of the PI485 are correctly set
as follows:
• The LED01G blinks as many as the number of the connected indoor units.
• The LED02G and the LED03G continue to blink alternately. (When the LRA/CRUN is
connected, the LED02G may blink more than the LED03G.)
If the LED is abnormally different from the above description, check again the indoor unit address
setting and the DIP switch setting.
