4. Setup and Initial Use
Follow these steps to set up your Tiffcofio Outdoor Mechanical Timer Outlet:
- Locate an Electrical Outlet: Choose a suitable outdoor electrical outlet that is close to the device you wish to control. Ensure the outlet is properly grounded and protected.
- Set the ON/TIMER Switch: Locate the slide switch next to the timer dial. Set this switch to the "TIMER" position for automated operation. For continuous power, slide it to "ON".
- Plug in the Timer: Plug the timer's power cord into the outdoor electrical outlet.
- Set Current Time: Turn the timer dial clockwise until the arrow head on top of the timer aligns with the present time. The dial is based on AM/PM, with numbers 1-12 repeating for both AM and PM. For example, 1 PM is indicated by the '1' in the second half of the dial. There is no need to adjust the pins for setting the current time.
5. Operating Instructions
This mechanical timer allows for up to 48 ON/OFF settings within a 24-hour period, with each pin representing a 30-minute interval.

- Determine Desired ON/OFF Times: Identify the specific times you want your connected device to turn ON and OFF.
- Set Timer Pins:
- To set an "ON" period, push down all the grey pins around the dial corresponding to the desired ON duration.
- To set an "OFF" period, ensure the pins corresponding to the desired OFF duration are in the "UP" position.
Example: To turn the timer ON at 5 PM and OFF at 10 PM, push down all the pins from the 5 PM mark to the 10 PM mark on the dial.
- Connect Your Device: Plug your electrical device directly into one of the grounded outlets on the timer. Ensure your device's own power switch is set to the "ON" position for the timer to control it properly.
- Verify Switch Position: Double-check that the ON/TIMER switch on the timer is set to the "TIMER" position for automated operation.
- Manual "Always ON" Feature: If you need continuous power, slide the ON/TIMER switch to the "ON" position. Remember to switch it back to "TIMER" for programmed operation.
- Power Failure Reset: In the event of a power outage, the timer will stop. Once power is restored, you will need to reset the current time on the dial (Step 4 in Setup) to ensure accurate timing.
