return valve actuator not working
I have a pretty standard pool/spa set up with a Pentair VS, EasyTouch panel and jandy valves with actuators. When I switch from pool to spa the valves work just as they should. However, when I want to switch back to pool the return valve doesn't move, it stays open to the spa. Moving the toggle switch to the other position does nothing. The actuator seems dead in all settings except spa where it responds as it should. It doesn't matter if I'm in auto mode or service mode it behaves the same way. The suction valve operates just fine either through the panel or manually.
I've opened the back of the actuator, which is essentially new, and there is nothing obviously amiss. I checked the EasyTouch low voltage section and everything seems to be hooked up correctly. I have a feeling it's in the programming somewhere but even after careful study of the user's manual I don't have a clue as to what the problem is. At present I only have the pool scheduled to come on for 8 hours a day automatically. With the return valve not working I don't dare schedule the spa.
I'd appreciate any thoughts.
