I have a speck pump and recently had to replace the timer. The timer was sent from speck itself. I had my electrician put it in. First my last timer had three settings - auto off on. This timer has only auto and on. The on position does not work. The auto works and I am able to adjust with the pins but nothing happens when I switch it to on. I called speck they sent another timer which I again put in and it's still doing the same thing.
