I have the manual for this softener, but I'm still unclear about this: If I set the calendar override to some value other than zero, am I forcing it to regen at that interval, or will it still make a decision at that time? I've had it on zero (auto regen based on usage) and think I may be using a ton of water. I'd like to set it so it will regenerate at most every 3 days, but not do it if it doesn't think it needs to based on usage. Thanks.
