Power outage shouldn't have affected the programming (as they're working off of a laptop)?
Anyway - ASS should remember last setting once you have it coded, however if you have the setting set to "off" and then switch to eco mode, eco mode automatically re-engages ASS, so you will need to turn it off again (even if you have had it programmed). just an FYI.
