We installed a GE water softener recently. Today we had to turn off
the circuit breaker for reasons not related to the water softener ....
anyway, when we turned it back on I went out to adjust the clock on the
water softener .... and it still had perfect time. There is no mention
in the manual of a battery backup and I don't remember us putting a
battery in....so does anyone know about these? Can't find anything
about it on FAQs or DIY. Thanks.
I think sometimes the microprocessors (or more accurately the circuit
board) contain a small battery just for saving settings and clock time,
etc. Or maybe even a small capacitor does the job. Sounds like you
found a nice and unexpected feature. It's things like that that make you
remember and recommend those products.
