21) Auto Swing Control (Excepted FDR, FDU, FDFL 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 times 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
J7 [FDTN (P), FDEN (P) models] or J3 [FDT model] 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. (Excepted FDKN (P)
model)
¡
Movement of louver when the power supply to the controller controlling 4 positions of the louver is switched
on. (Only FDT model)
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.
