My pool is 15,000 gal and my spa is 700 gal. In pool mode, the spa overflows into the pool, therefore the autopilot chlorinates spa and pool to the same ppm's. In spa mode, there's only circulation in the spa, and the autopilot does not come on.

I also have solar and when in pool mode it heats the spa and pool to the same temp. In spa mode, it only heats the spa.

The autopilot and solar work against one another.

I'd like to keep the spa at a higher temp than the pool and I'd like a higher chlorine concentrtion in the spa, but I can figure out how to do it.

I run the pump in pool mode for 3 hours and in spa more for 3 hours each day, while the sun is shinning. The pool is heated to almost 80 and the spa reaches about 95 --- solar is working great!

The autopilot only runs when in pool mode and therefore the three hours in pool mode brings both the pool and spa to about 3ppm's of chlorine. I'd like to keep the pool at 3 ppm's and raise the spa to about 5ppm's. If I run longer in pool mode I will get a higher overall chlorine concentration, but lose heat in the spa. If I run it longer in spa mode, I will get more heat in the spa, but the overall chlorine concentation will drop. Basically, I can't figure out how to get different chlorine concentations in the the pool and spa and heat the spa to a higher temp than the pool.

Has anyone else experienced this problem and what have you done to solve it?

Thanks,
