I just recently bought a house with a pool/spa. The heater was dead when I moved in and just had a new F400HDN installed. The pumps are set to run overnight between spillover for the majority of the time, and then spa mode for a short period thereafter.
I noticed this AM that the heater was heating the spa when the spa was on. I do NOT want this. Is there a way in the Aqua Logic board, it can be set that the heater ONLY turns on when explicitly told to do so, no exceptions? I only plan on using the spa a few times a week. I'm still trying to learn how all this stuff works, so I apologize if that's a dumb question.
Thanks very much in advance!
