Hi Jeanne,

Here's a page with detailed instructions and pictures - that will guide you through programming. I hope this helps & good luck!

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.

Open following link to identify TN300 analog timer and read instructions and download possible manual:
If TN300 is not same as your timer, view images on link and then add a comment for possible help with different timer.
