We are going through a pool remodel. We recently had a plumber install our Hayward VSP to the Intermatic timer. I thought since the Hayward had a it's own timer that there was no need to connect it to the timer, but that's what he did without really explaining it. The thing i found odd was that our heater was making a buzzing sound. It's gas powered and wasn't on, but it's still consuming some electricity. I'm thinking that I haven't heard this in the past because the single speed pool pump probably was louder than the buzzing sound. They both were turning on and turning off at the same time since it was connected to the timer.
Is there a right/wrong way to wire this - direct to a circuit breaker vs the timer? Or are there any pros/cons to either design? My goal was to save on electricity, but now if i run the VSP for 12+ hours a day then I'm stuck with the heater most likely consuming energy as well. Should I hire a 3rd party to check the work??
