Wiring Error Check
Use to verify if wiring is properly installed.
1. Shut power down to the system.
2. Set DIP Switch 2 to ON.
3. Turn power on to the system.
4. Check if the Red and Green LEDs on the outdoor unit PCB are ON (indicate indoor units are in forced
operation mode).
5. If the wiring is correctly installed, the Green LED will light up. If the wiring is in-
correctly installed, the Red and Green LEDs will blink, indicating which part of the
system is in error.
• Red LED = Piping Number
• Green LED = Wiring Number (Room)
Example: If the Red LED blinks twice and the Green LED blinks three times, the second
piping to the third room is in error (see at right).
• If the indoor unit(s) are not communicating properly to the outdoor unit, the Wiring
Error Check cannot operate correctly.
