Woods timers sometimes have more than one number for same timer.
This is true for most brands of timer.
Companies change model numbers and add new model numbers.

Intermatic makes two different analog timers with 111 model number. TN111 and HB111.
Grasslin has older electronic timer Tactic 111
Timex sells TE111 timer.

I Googled in Diehl digital timer and located a website that had the exact timer I have. Included in the list of information was a manual with instructions on setting the timer. I downloaded the instructions and set the timer. Exactly what I needed.

1. Press and hold SET until day flashes. Use arrow keys to set
2. Press SET again and hour should flash. Use arrow keys
3. Press SET again and minutes should flash. Use arrow keys
4, Press SET again to exit time-set mode.

call 1-800-562-5625 they will email instructions to you ....

If it's the same as ours (clock button top left, clear bottom left):

1. press and hold clock until the clock starts to flash
2. set time using h/m/s keys
3. press clock again

Hope it works
