Dood!!! I have that same timer, and the same company makes like 10 identical looking models, and each model has a different way of setting the hours, and I fucked up my lighting schedule on my mother b/c I didn't put all the PINS down for my dark period... It's probably fried my bulbs turning on/off at what I had it set at. I wish I would've noticed this thread sooner. Those are reliable timers, but the different ways to set those timers cause all sorts of confusion.
PPL need to make sure that all timers they buy are grounded timers; I made multiple trips to lowes due to my ignorance/carelessness.
