Hello, I have a Hayward Summit XL 50amp 140,000 BTU electric pool heat pump. I am trying to make a simple on/off smartthings switch for it. On the computer board there are 2 terminals for a remote switch (open/close). I am assuming I can easily hook up a dry contact relay like the mimolite for example, to those 2 terminals, please correct me if i am wrong. The other piece is powering the device (mimolite) as I do not have a recepticle outside near the unit. The heater’s computer board also has 24VAC. Could I tap into that somehow?
