Gotta admit, I feel like a tool for not being subbed to this fine journal of yours already. Doh!
On the timers... I've had issues with timers and digital ballasts, too. It's difficult to find reliable timers it seems, as different digi ballasts seem to affect timers... differently. For some, no issues ever. For others, nothing but problems. Seems like there's some major inconsistencies with ballasts that some timers struggle with - not sure why.
I had Apollo 9's that did the same thing, but then also heard about not being digital friendly with those either. BUT, here's the rub. These timers are mass produced and licensed (at least the Apollo 9's). In other words, a dozen other vendors sell the same timer with their own label on it. Most of them don't claim it to be "non digital friendly" either. So... I think they rebrand something that ended up having some limitations, for whatever reason. Where they typically shine (Titan), is on their higher end timers, controllers and products as well as (typically) pretty decent customer service (IMO). I found pretty reliable timers from "Intermatic" that I like so far, but not sure if they have something that's good for 240v, etc...
