LED being ON indicates output active (L). LED being OFF indicates output inactive (Z). Only one output among
LO, MI and HI may be active at a specific time.
* Rhythm LED and Sleep LED indicate SC2128A operation modes.
* Swing1 LED, Swing2 LED and Light LED indicated respective output status of SO1, SO2, and LIT.
* Four LEDs (Tb0, Tb1, Tb2, Tb3) are used to indicate the off-timer period. Depending on the base timer step
The time schedule is the sum of all ON LEDs. For example, if SC2128A is programmed with 0.5/1/2/4 hour
