WIRED REMOCON
(1) Modifying the indoor unit’s printed circuit board
• Cut the jumper (printed “WIRED REMOCON”) attached on the board.
It is impossible to control by the wireless remote control after cutting the jumper.

5.7 Installation of wired remote control and super link adapter (SC-AD-E) (Op-
tional parts) (STM, SRRM only)
Notes (1) Controlling multiple indoor units using a single remote control.
● Up to 16 indoor units can be controlled with a single remote control.
a) Run 3-wire remote control lines between each of the indoor units. See “Cautions when extending remote control
lines” on page 94 concerning extended remote control lines.
b) Set the remote control communications address on “0” ~ “F” using rotary switch SW11 on the indoor unit’s control
board, taking care not to overlap the addresses of any of the units.
c) After turning the power on, press the AIR CON No. button to display the indoor unit’s address. Be sure to confirm
that the settings are displayed correctly in the remote control by using the
and
buttons to display the address
of each connected indoor unit.
(2) To connect the super link, the optional SC-AD-E (super link adapter) is required.
Beware of wrong connections in refrigerant piping and wiring
● Make sure to match the piping and wiring from each unit to the outdoor unit.
● Be careful because if connections are wrong, normal operation cannot be achieved and may damage the compressor.
