I'm looking for a timer with a specific functionality. I want to be able
to set the thing to turn on an electrical appliance at a set time, then
turn it off after a selectible time. I don't want the thing to come on
again until I tell it to. Not one day later or 7 days later.The
application is for the pre-heaters on my RV-6. I've got a battery warmer
and a sump heater.

The low-down is that I work 15 minutes from the airport, so I can drop by
very easily at lunch or right after work to set a timer if I think I'm
going to be flying the next day (this is particularly useful for flights
early on Saturday morning). There are many timers that will support this
function. The problem is that most of 'em will then turn on again at the
same time the next day, and the next, and the next. Or maybe, they will
turn on a week later. The situation I want to avoid is where I set the
timer for, say, Saturday morning, then plans go bad and I don't get to the
airport for a week or two and the heaters run on a daily basis or weekly
basis until I reset or unplug the timer.

I've tried the big box stores, Grainger, etc. and have not found a timer
that works the way I want.

Suggestions?
