Alarm code

Incorrect Indoor number setting
• The RUN LED ickers and “ALARM” is displayed on the remote control switch.
• The unit number, alarm code and unit model code appear alternately on the Set Temperature display of the remote
control switch. The alarm code also appears on the outdoor unit PCB display.
- The alarm code appears three minutes after the outdoor unit power activation if duplication is detected in indoor
unit numbers connected to an outdoor unit (one refrigerant system). This applies when indoor unit numbers are
congured using the rotary switch (RSW1).
- The alarm code appears when the more than next indoor units are connected to one outdoor unit.

RAS-(2-2.5)HVNP
RAS-3HVNC

- The alarm code appears when the indoor and outdoor unit refrigerant system and address are set to 64 or above.
(In such a case, the alarm code “b1” appears on the remote control switch.)
