4. Setup and Programming
This section guides you through setting up and programming your Woods 50021 timer. For a visual demonstration, please refer to the video below.
Video: Demonstration of setting a Woods Indoor Mechanical Timer. This video illustrates how to set the current time, program ON/OFF intervals using the pins, and utilize the manual override switch.
4.1 Setting the Current Time
- Plug the timer into a wall outlet.
- Rotate the dial clockwise until the current approximate time aligns with the arrow labeled "TIME NOW". PM hours are shaded on the dial for easy identification.
4.2 Programming ON/OFF Times
The timer dial has segment pins around its circumference. Each segment pin represents 30 minutes.
- Ensure all segment pins are initially pulled UP (OFF position).
- Push the segment pins DOWN for the period(s) of time you want the connected device to be ON.
- Leave the segment pins UP for the period(s) of time you want the connected device to be OFF.

The timer includes a manual override switch located on the top of the unit.
- To permanently turn the connected device ON, slide the switch to the "OUTLET ON" position. This bypasses all programmed settings.
- To revert to the programmed timer settings, slide the switch back to the "TIMER ON" position.
5. Operation
Once the current time is set and the ON/OFF intervals are programmed, the timer will automatically activate and deactivate connected devices according to your settings. The dial will continuously rotate, indicating the current time and progressing through the programmed cycles.
