Ted... you're kidding right? Josh is my Go To Guy!
In addition to what's already mentioned;
- No HIGH salt limit shut down, which means that any accidental overdose of salt (such as at start up, or when the salt level is incorrectly displayed and you should happen to add salt (BECAUSE THE UNIT SAID SO)), the AutoPilot will continue to operate while the Goldline will require you to drain your pool down to dilute the salt level.
- Temperature Compensation - not only adjusts the output for you automatically, under cold water conditions, most system will shut down when temps fall below about 60 degrees or less, AutoPilot will continute to operate, so you don't have to add chlorine by hand over the winter months, if you should happen to continue to run your pool. You didn't mention where you are so I don't know if this is applicable.
- Adjustable Reverse Polarity - which accomodates improper water chemistry balance to prevent scale formation on the cell blades.
- Adjustable Cell Power - which allows you to increase, or in your case, lower the output of the system so as to avoid overchlorination
- Two Boost Modes - 24 hrs and 72 hrs, which also has a memory to recall how many hours are remaining in the boost mode. When the pump shuts off, the AutoPilot knows how hours are left, so it will start back up in Boost Mode. I believe Goldline cycles off when the pump turns off... Ted? Scott? Is this correct?
- Cell Life - Lets say that they estimate cell life like ours, approx 10,000 hrs of operation. Simply due to the fact that their larger cell produces 1.4 lbs/day vs our RC42 cell at 1.78 lbs/day, means you will run the AutoPilot cell less time, to maintain your desired chlorine level. The result of which is our cell will last longer. Therefore, does the minimal price difference really factor in? We may cost more for the replacement cell, but you don't have to replace as often...
OK, I'm off now. Fringe is back on the TV!!
