Looking back at some older posts and I see your hasn't been answered by anyone in the forum. What a shame. By now your pool is probably all full and operational, but I wanted to check to be sure. Let us know if you still have any questions. Have a good day. 
You can Configure the system and just keep your breakers off so that non of the pumps get turned on by mistake. You can also NOT Enable your schedules, but it’s probably safer to just keep the breakers off until your pool is up and running.
I'll second this - I did this on my initial OmniLogic configuration and I do it every year around this time. Just make sure all your breakers are off and, as long as everything is wired up as it should be, you can play with the OmniLogic as much as you want. This way everything is ready and you've already tested the configuration. When opening time comes around, all you have to do is flip the breakers on and go.
