What should be on during freezing temps

[Hen429]

Hi! I'm down in Houston. My pool cleaner said we had a freeze guard on our pool. He told me that the pool and filter light should be on but all these other lights are on. It's 25°. Should I switch it to pool, turn on the filter and the water feature? Does the booster pump and cleaner need to be on?

The booster pump should be on, along with any other piece of equipment or set of pipes.

How many pumps do you have, what are your water features, and do you have a spa? You want to make sure water is circulating through everything, otherwise the pipes/equipment will freeze if there is just water standing in there. Lights do not matter. Do you know the "not used" circuits that are lit up?
