The low-end Intermatic products ARE junk. Use the SS7C - it is much
better designed and will handle inductive loads (that's the root cause
of your problem - the large inductance of the long load circuit).

Hi Frank -
Well, I'm in a warm southern climate, so maybe the problem was
temperature related. I can't imagine why a wide temperature swing would
cause the relay to fail. Perhaps it was a failure in one of the
electronic components that drives the relay.
What functionality specifically are you looking for in a wall
timer....random on/off periods or fixed on/off periods (how many),
battery backup *yes*...what else?
Here's two wall switch timers that might work for you. Haven't tried
either one, so I can't vouch for their reliability.

Another option might be to eliminate the wall timer and install a
in-line industrial duty time switch at your electrical panel. Assuming
that the lighting you want to control is on it's own circuit, of course.

Are you referring to Aube?
I have recently installed about 6 of their timers. I *really* like the
fact that the switch and timer sit flish to the plate and look just
like a regular Decora paddle (other than the LCD window). My only
(minor) reseravation is that the cover is a bit difficult to open to
change the settings and I am concerned that it might eventually break
off (though to date I have not had any problems). Cost is about $30-35.
Looks exactly the same as the Aube timer. Not sure who OEMs for whome
but seemingly identical.
