- Only slave unit addresses can be set in this way. Master unit
setting is not possible.
- If you make the DIP switch settings after the power has been
turned back on, carry out twin/triple automatic address resetting.
- Be sure to set DIP switch 1-8 to ON when setting twin/triple
addresses. If DIP switch 1-1 is set to ON without setting 1-8 to ON
also, group addresses will be set instead, and the remote control
open circuit error code (F26) will be displayed.

Function
- This clears the current twin addresses which have been set
automatically, and causes automatic twin address setting to be
carried out once more.
Procedure: Press the ADDRESS RESET switch SW3 (push button switch) on the outdoor unit
circuit board continuously / until LEDs 2 to 8 on the outdoor unit circuit board are all
illuminated (takes approx. 3.5 seconds).
Operation: The outdoor unit will reset the addresses for the indoor units which it is connected
to, and will send an instruction / to carry out automatic address setting again. If the indoor unit
DIP switches have not been manually set for / twin address setting, the indoor units receive
this command and they then clear their existing settings and carry / out automatic address
setting.
If an indoor unit has had its address set by the DIP switch (DIP switch 1-8 is ON), or if the remote
control unit is connected to one of the indoor units, then the addresses for those indoor units
cannot be reset.
- The indoor units will not run for approximately 1 minute while
automatic twin address resetting is being carried out.
- Do not turn off the power supply for at least 1 minute after
automatic twin address resetting has been carried out.
