We bought a house with a pool last June, and I have been following the TFP approach since then mostly with good results. One thing I still can't figure out is my pump timer (see the attached picture). It is my understanding that during the winter, when we don't use the pool at all, I should only be running my pump for about 30 minutes when I add chlorine. How do I do it with this timer? Currently, the pump gets turned on by itself during the day, and I don't want it to happen. I only want to turn it on at around 9 pm when I add chlorine.
