Setting Schedules
The timer dial has 96 small pins, each representing a 15-minute interval. To program an 'ON' period, push down the pins corresponding to the desired time frame. For 'OFF' periods, leave the pins in the 'UP' position. Ensure the manual switch is set to 'AUTO' for the programmed schedule to take effect.
In case of a power failure, the timer's current time setting may need to be reset manually once power is restored.
