Thank you both. I added the pool details to my signature (need to add the robot).
It was cold (75*) here in Florida last night and I was trying to heat the spa. I know the rest of my valves pretty well, but this was the first time I have touched the heater since the pool was built. The PB just set everything up and walked away, and didn't even connect the Aquacal to the RS6 for control, so I had to figure that out after a few drinks, but in the end I got it all working, it just took a while to heat the spa (probably because I was bypassing 35% of the flow).
One last question if you have time. When running the heater what speed should the pump be on? I can't find any documentation on minimum RPM, but when it is on 3450 the jets pulverize me.
