Title: even with battery backup it looses it's programming every time main power is lost
Review: I got this as a timer for my block heater, I mounted it in my truck, but it is not keeping the program, it does keep time, but does not remember to run the program after the power is lost, so for me it is an expensive switch. I know I'm not using it the way it is designed, but, buyers should be aware that it will either be on forever, or off forever after a power failure, depending on whether it was off, or on when the power went out.
Is the review positive or negative?
