20.1.4. Automatic address resetting for twin/triple systems
Function:
- This reset the current twin/triple addresses which have been set
automatically, and result in the reoccurance of automatic twin/
triple address settings.
Procedure:
Press the ADDRESS RESET button 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
approximately 3.5 seconds).
Operations:
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 switch
have not been manually set for twin/triple address setting, the
indoor units receive this command and 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 unit,
then the addresses for those indoor units cannot
be reset.
- The indoor units will not run for approximately 1 minute while
automatic twin/triple address resetting is being carried out.
- Do not turn off the power supply for at least 1 minute after
automatic twin/triple address resetting has been carried out.
