I have a jandy controller. The panel is in the house. The controller box is outside next to the filter. From that it is connected to a pool pilot dig 220. Question. Why isnt the display board on the pool pilot working? I can't even run the pump for the pool. I am assuming no power to the pool pilot. From the jandy controller in service mode I can here the relay click, but nothing. I can run the pump for the water falls. I think the pump for water falls is in same relay as pump for pool. Do I need a new pool pilot? Can I check to see if approprite power from jandy is going to pool pilot? I am handy with a volt meter. I do not see anything burnt inside the pool pitol. I can also turn on lights in pool. Also, I can remotly turn valve for solar heat in service mode.
