I lost my instructions for my Stanley timer 31221. It has a simple single button to toggle through F, 1-9, 1.-9. etc. I just do not remember the exact detail for the numbers. I think if you select 2 then it comes on at dusk and stays on for two hours? I think the 2. means it stays on longer the first day and sticks to the two hour schedule thereafter? Please clarify if you can.
