Thanks for the clarification. The SPST Relay would be in front of my current relay. I guess it can pull in my relay using the additional 24VAC power supply. I’ll have to mock it up and see if it works with my GE relay. My RainBird system has a 24VAC relay with a 650mA limitation and it worked great for years. So obviously my GE relay draws less than 650mA.
