I'm wondering if any Spa/Hot Tub companies are making programmable heat cycles? I'm hoping to purchase one in the next month and not sure if any brands out there have features that allow customizing. What I really want is something that will allow me to set my heating lower during the week when we aren't around and Fridays bring the temperature back to our optimum soaking temperature for the weekend. Not having much luck with google and going from site to site is kind of a pain, so hoping someone might have suggestions out there! THANKS.
