I am looking to hook up my timer to a pool pump/heater. I was initially concerned about installing a fireman’s switch due to the heater but I talked to Hayward and they said their heater does not require one due to design and shut off features. I even tested pump on 1st stage and heater shut off. I was wondering if I should install timer off of breaker panel or outside by pool to control outlets. Also recommendations for timer brand/type.
