The interval light is on. I have a pump in the first and last socket. The tide mode is on and everything works fine if the dial is kept at the min. possition. If I turn that dial even slightly, then one pump stays on all of the time, they do not switch. I have is set for 7-75 min right now and am pretty happy with the 7 min. So I'll wait till you have the stuff in stock.
Thanks,
Dave
