Setting the Current Time and Date (If Applicable)
Digital Stanley light timers, like the 51217, require accurate time and date settings for proper scheduling. Typically, a “Set” or “Program” button initiates this process. Use the hour and minute buttons to adjust the current time, paying close attention to AM/PM indicators. Date setting follows a similar procedure – month, day, and year.
Incorrect time or date settings will cause scheduling errors. Refer to your model’s manual for specific button functions and display readings. Some timers automatically synchronize with the current time after initial setup, simplifying this step. Verify the accuracy after initial configuration.
On/Off Scheduling: Simple Timers
For basic Stanley timers, like the 31198, scheduling involves defining “on” and “off” times. Locate the program buttons – often labeled “Set,” “Timer,” or similar. Press these to enter programming mode. Then, input the desired “on” time (when you want the lights to activate) and the “off” time (when they should turn off).
These timers usually operate on a daily cycle. Ensure the correct AM/PM settings are selected. Some models allow multiple on/off cycles per day. Review your settings carefully before finalizing to guarantee the lights operate as intended. Simple, yet effective automation!
Advanced Programming Options
Stanley timers, particularly the Select Outdoor 51217, offer enhanced features. The photocell function automatically activates lights at dusk and deactivates them at dawn, ideal for outdoor use.

Adjust sensitivity settings, if available, to fine-tune activation thresholds. Proper placement is crucial; avoid direct light sources. This function simplifies outdoor lighting control, enhancing security and convenience without manual intervention.
Countdown Timer Feature Explained
The Stanley LightTimer Select Twin boasts a convenient countdown timer, ideal for temporary lighting needs like holiday decorations. This feature allows you to pre-set a specific duration for your lights to remain on, after which they’ll automatically switch off. Simply select your desired runtime – from minutes to hours – and the timer handles the rest.

This eliminates the need to remember to manually turn off lights, saving energy and providing peace of mind. It’s perfect for festive displays or temporary outdoor illumination, offering automated control and convenience.
Troubleshooting Common Issues
Encountering problems with your Stanley light timer? Common issues include the timer failing to turn lights on or off as scheduled. First, verify the correct program settings and ensure the current time and date (if applicable) are accurate. If using the photocell, confirm it isn’t obstructed.
