Question: In case of Power Cut, do you have to re-program it? or does it retains the stored program inputed into it already?
Document: I an not satified because the swith is not dpst as i was lead to believe by pics. The switch has one set of common contacts and a single through set. Which mean in USA it can be used for 110 / 120 volt. If i understand correctly China power is 220 volts on one leg and a common or ground on the other.
i installed it and gave up on the bad chinglish directions, which referred to buttons and functions it did not have and simply proceeded to try to figure it out. once i got it figured and working (not too difficult if you have patience), it has worked fine, so fine i would like to order another as a spare -- the price is right.plus it does not make the groaning noise the intermatics develop.
for at least 40 yrs i have used the old low tech clunky intermatic timers for water heaters, pumps, etc. and i am the sort who trusts the old machines more than the new high tech crap. but when i was looking for a replacement for my intermatic that had timed the water heater for the past 15 yrs but crapped out due to weak springs and plastic parts, i got offended by the prices they are asking.
Practical & cheap ! it is useful (at least  for me ) . you can use it as an automatic switch timer or & as a manual switch . Just two sensitive notes : Body material (plastic) is very thin & you need to use very small screws to fit it on wall ...etc .
Perfect item for me. Hope it lasts though, at this moment too early to say.Did you know you have to stupidly fill this with a minimum of words as if a reaction cannot be useful if it is brief.Long enough now?
