I'm a big fan of the automation by Pentair. Easy to setup and easy to use.

I also understand that its a considerable investment. Thats why I sell so many of the universal replacement timer mechanisms for the intermatics.

Its a fairly simple 20 minute replacement. You'll want to throw the circuit breaker for the pool equipment first. Be sure you've got a good solid ground on your timer, and that you get the plastic wire gaurd back on.
