I am wanting to keep my pool temperature at 78-80 or so. I have a reverse cycle Aquacal heat pump and would like to know if it more cost-effective, to cool the water at night down to 75, turn OFF the cooling when I get up in the AM and let it warm up some as the day goes on, rather then leaving a temperature setpoint on all the time? I also want to shutdown the pool pump for a number of hours during which time I cannot have the heat pump on (or maybe I can and the FLO condition will keep it off?).
Any strategies for how to most efficiently cool (and heat) pool water?
