Patent ID: 7736522

Claim:
An automated method of sanitizing a first body of water and a second body of water with electric current from a single shared power source, the method comprising: (a) circulating water from the first body of water through a first circulation system, the first circulation system having a first sanitizer generator; (b) circulating water from the second body of water through a second circulation system, the second circulation system having a second sanitizer generator; (c) sensing a parameter of the water in the first body of water related to a need for sanitization; (d) selectively delivering electric current from the power source to the first sanitizer generator to generate sanitizer for the first body of water when sanitization is needed; (e) sensing a parameter of the water in the second body of water related to a need for sanitization; and (f) controlling with a shared control system, selective delivery of electric current from the shared power source to the second sanitizer generator to generate sanitizer for the second body of water when sanitization is needed.
