remote control unit. Note that individual operation is not possible.
20.1.1. Twin and triple operation setting
- The master unit and slave units are set automatically when the
power is turned on. At this time, the indoor unit which is
connected to the remote control unit becomes the master unit. / (If
automatic setting is not possible, carry out the settings manually.)
- No distinction is made between master unit and slave units (slave
unit 1 and slave unit 2) at the indoor unit or remote control.
- Install the remote control to the master unit. (It cannot be
connected to slave units.) / If indoor unit models with louvres and
models without louvres have been connected together, use an
indoor unit with louvres as the master unit.
- The remote control termostat can also be set.
- Optional circuit boards can only be installed to the master unit.
- Setting the master unit and slave units can also be carried out
manually by using DIP switches. However, manual settings will
always take priority. If you have made manual settings but would
like to return to using automatic settings, set all slave unit DIP
switches (refer to the table below) to the OFF position, and then
press the ADDRESS RESET button on the outdoor unit (SW3 on
the outdoor unit printed circuit board). / (Do not mix manual
settings and automatic settings.)
