Does anyone know of a company that makes their hot tub / spa
controller such that it can be programmed to automatically set back
(lower) the temperature should it be left on?

We are evaluating installing a community spa for our HOA and we are
concerned that someone could turn it up and leave it without turning
it back down. It will be outside in the winter and usually only used
on the weekends and we would not like to have it automatically reset
it's temperature after a certain amount of time.

Thanks for your input.
