4. MODE KEY  
MODE key is used to bring SC2128A around ORD  
(ordinary wind) mode, RTM(rhythm wind ) mode, SLP  
(sleep wind) mode and RSL(rhythm sleep wind ) mode. In  
ORD mode, the wind speed is set by SPEED key and does  
not change as time passes. In RTM mode the wind speed  
cycles through three rhythm wind, patterns as set by the  
SPEED key. In SLP and RSL mode, however, the fan  
automatically steps down one level (strong to middle,  
middle to low) every 30 minutes and keeps in low wind until  
off-timer times out. Four modes of operation are described  
in details later.

5. SW1 and SW2 KEYS  
SW1 and SW2 keys control the output status of SO1 and  
SO2 outputs which in turn control the head swing of fan.  
Depending on the 2SW mask option, SO2 is controlled by  
either SW1 or SW2 key. If 2SW option is selected each  
pressing of SW1 key toggles SO1 ON(L) and OFF(Z) and  
each pressing of SW2 key toggles SO1 ON(L) and OFF(Z).  
If 2SW option is not selected, pressing SW1 key cycles  
SO1 and SO2 output as shown in the diagram and SW2  
key has no effect. 2SW option is described later.

6. LIGHT KEY  
LIGHT key toggles LIT output on(L) and off(Z). LIT output can only be controlled with LIGHT key (from both  
panel and remote control) and SLEEP key (if available) on remote control handset. OFF key does NOT affect LIT  
output. LIT output is NOT affected by OFF key as well as off-timer times out.  
7. OFF/MEMS KEY  
OFF/MEMS key functions differently depending on whether the fan is ON or OFF. It functions as OFF key when  
the fan is ON, and is used to bring SC2128A from any on state into off state. LIT output is NOT affected by OFF  
key. When fan is OFF, it functions as MEMS (memory start) and is used to turn on the fan and set to the memory  
mode, provided memory mode is enabled. Memory mode is explained later in the MEMORY MODE section.  
8. INDICATOR LEDS  
Up to twelve(12) indicator LEDs may be constructed on the control panel of fan built with SC2128A. Six(6)  
LEDs are constructed as 3x2 LED matrix formed by COM and LED1, LED2, LED3. The other six(6)LEDs are built  
in series with TRIAC outputs. The diagrams show how the LED matrix is constructed.
