b) Control of input signal
(Make sure to connect the standard remote control unit. Control of input signal is not available without the stan-
dard remote control unit.)
Control of input signal (switch input, timer input) connectors (CNT) are provided on the control circuit board of
the indoor unit.
However, when the operation of air conditioner is under the Center Mode, the remote control by CnT is invalid.

19) Auto Swing Control (Only FDT models)
¡ Have a louver motor to move the louvers up and down for the so called “auto swing” function.
¡ The louver auto swing starts when the AUTO SWING key is pressed once and stops when the AUTO SWING key
is pressed again. The louver position is displayed on the LCD on the remote controller. During auto swing, the
position displayed on the LCD changes, but the positions of the louvers and the display are not coordinated. (The
louvers swing 3 - 4 ti))mes per minute but the display changes once per second.)
¡ Stopping the louvers
When the AUTO SWING key is pressed to stop the louver movement, the LCD louver-position display stops and
the louvers stop when they come to the position displayed on the LCD. There are four louver stop position on the
LCD. (When jumper wire J3 on the indoor unit printed circuit board is cut, the louvers stop immediately at the AUTO
SWING key is pressed to stop them and the LCD display changes to show this position.
¡ Movement of louver when the power supply to the controller controlling 4 positions of the louver
is switched on.
When power supply is switched on, the louver will automatically swing about 2 times (without operating remote
controller). This is an action for the microcomputer to confirm the louver position in order to input the cycle of the
louver motor (LM) to the microcomputer with the limit switch (LS) pushing the louver motor (LM). If the LS action
is not input to the microcomputer, the louver will stop within 1 minute after the power supply is switched on and
will not move from then on.
