    When in spa mode you want the suction port set to come 100% from the spa. If you accidentally draw any water from the pool the jets will be cold.

    Yeah, when heating the spa, you don't want to see any spillover to the pool.

    The last time I had a bunch of people over to swim, the spa was a lot warmer than the pool and as the sun went down, the kids gravitated towards the spa. When they didn't want to get out, I just killed the heat and moved the valves and chilled them out.

    Troublefree does not mean Maintenancefree. It's like brushing your teeth: You can spend a couple minutes a day and pennies a week or go to the dentist once a year and spend several thousand dollars.
    A pool is like a pet - you have to feed it every day, even the days you don't want to play with it!
