5. Operating Instructions
5.1 Programming ON/OFF Periods
The timer allows you to set specific ON and OFF times in 15-minute intervals over a 24-hour period.
- Identify Time Segments: Each push-down pin around the blue dial represents a 15-minute interval.
- Set ON Times: Push down the pins corresponding to the time periods you want the connected appliance to be ON. When a pin is pushed down, the timer will supply power during that 15-minute segment.
- Set OFF Times: Leave the pins in the UP position for the time periods you want the connected appliance to be OFF. The timer will cut power during these segments.
- Connect Appliance: Plug the appliance you wish to control into the timer's socket.
- Activate Timer: Ensure the red manual override switch on the side is set to the timer icon (usually a clock symbol or a line). If it's set to the 'I' position, the timer will provide continuous power, bypassing the programming.
