So we are the proud owners of a new pool. We used the spa for the first time Christmas Eve! Anyway, I have a question about cam settings and run modes for our pool. The NPC has set the return valve cam so when the controller is in "pool" mode, it is sucking from the pool and returning to both the pool and spa (50-50). He says he always sets the valves this way, but didn't really give a good explanation of why. The downfall to this is if I heat the spa for an evening, and want to heat it again the following evening, all of the hot/warm water was pumped out during the day's filter cycle. Any thoughts on why the NPC would set it this way? Unless told otherwise, I'm going to change the cam so pool mode is truly just that.
PS I just found this site, but it is great!
