I cannot find manual for that product. I think it's actually an Intermatic product DT8003, but I can't find that manual either.
1) If you post the exact wording from the manual where it gets confusing, it would be easier to help ... and typing out the instructions on your part might help you solve the problem
2)
If I had to guess about the confusing part of timer programming:
-Timer offers DST option, and Dusk-to-dawn capability +> you have to decide whether to use these options or choose 'manual' option where DST is ignored. Read where you programmed this step and make sure you chose manual or auto.
-You can set 7 programs per week, Program1, Program2, etc
-Start with Program1: first, select days of operation for that specific program ... for example MO (for monday) or WKD (for weekend)
-After setting days of operation, Program1 has to have an ON time.
-After setting ON time. Program 1 has to have OFF time.
-After setting OFF time, you press a button to save Program1 (sometimes this step requires you to push the on-off button or manual override)
-Next, you repeat the same steps for Program2
-The timer ignores conflicting programs > for example Program1 says ON at 7 and OFF at 8 and Program2 say the opposite, timer will ignore both programs.
3) Post photo of instructions on
Flickr or
Imgur -Flatten instructions between pages of a book for a few days, and then scan instruction in file format (same format as you scan a photograph or have Office Depot scan instructions for you)
You can post the photo of your instructions on
Flickr or
Imgur ... and then we can go look at instructions and help sort out the confusion.
