11. SLEEP WIND MODE
In sleep wind mode, the wind speed steps down
automatically one level every 30 minutes, until it reaches
low wind level. If no off-timer is set, SC2128A keeps in
low wind level. Otherwise, it restores off state when
off-timer times out. To enter sleep wind mode, turn on
the fan by SPEED key first. Adjust to desired LO, MI, ST
wind speed. Press MODE key twice to bring SC2128A
to LOW, MIDDLE or STRONG sleep wind mode as the
LO, MI, ST wind speed set before entering sleep wind
mode. Press MODE key in sleep wind mode forces
SC2128A to leave sleep wind mode and enter rhythm
sleep wind mode.

12. RHYTHM SLEEP WIND MODE
Strong rhythm wind
Middle rhythm wind
Low rhythm wind
Pressing MODE key in sleep wind mode brings
SC2128A into rhythm sleep wind. In rhythm sleep wind
mode, SC2128A outputs LOW, MIDDLE or STRONG
rhythm wind pattern and automatically steps down one
level every 30 minutes until it reaches low rhythm wind
level. If no off-timer is set, SC2128A keeps in low rhythm
wind output. Otherwise it restores off state when the
off-timer times out.

13. MEMORY MODE
SC2128A features on-chip operation memory, in which operation state may be stored. OFF/MEMS key also
functions as a special MEMS(memory start) key. If this key is pressed when SC2128A is in off state, SC2128A is
activated into the operation mode stored in the operation memory. After power on, the operation memory is
initialized as follows: middle speed, ordinary wind, none off-timer setting, SO1 and SO2 swing head outputs both
off, LIT output off.
Operation memory memorizes the following:
(1) SPEED
low, middle or strong,
(2) MODE
ordinary, rhythm, sleep or rhythm sleep.
off-timer setting,
(3) OFF-TIMER:
(4) SWING HEAD
(5) LIGHT
SO1 and SO2 output state,
LIT output status.
If the fan is turned on by SPEED key, subsequent adjustments to the fan operation either from pannel key or
from remote control handset do not affect the operation memory. If, however, the fan is turned on by MEMS, the
subsequent adjustments to speed, mode, off-timer, SO1, SO2 and LIT output will update the operation memory to
