Response to I have a Hayward saltwater controller and this GVA-24. My understanding is as long as the solar panels are reading > the solar temp, it will heat the water to the solar temp. Regarding the manual toggle switch. I've read it's designed as "Auto 1, off, Auto 2". Currently though it seems to be functioning as "Opens Valve, Off, Closes Valve". Am I stuck in manual mode? Any tips on how to return it to an automatic mode, where the controller auto informs actuator to open/close? Thank you!
