Upgraded from intellitouch to intellicenter. I have 3 light circuits. They are scheduled to turn on at 6:30pm. At that time, I hear the relays (I believe) going "CLICK, CLICK, CLICK, CLICK" (and the lights in the pool turning on and off and on and off until finally they make up their mind and stay on). Sounds like alot of wear and tear. Why do they do that, and how can I stop it?
