SECTION 1. WATER QUALITY with the CAT 4000

The CAT 4000 revolutionizes the manner in which water quality can be monitored

and maintained. A pool operator typically checks, records and adjusts pool or spa

water chemistry hourly at best. The CAT 4000 continuously samples pH and

sanitizer activity, adjusting the feeding of chemicals on a basis proportional to the

demand. Hourly water quality readings are sent along with any alarms or service

requests through a wireless network to the POOLCOMM web server for remote

monitoring and management through any internet connection.

From the website, the subscriber can monitor water quality, print charts, graphs and

logs, change controller settings, and designate contacts for outbound notification via

email, cell phone or PDA. Optional digital flow and level sensors are available to

monitor flow rate, chemical storage tank levels, and even automate water level

control.

The results include elimination of "human error", accurate and reliable maintenance

of chemical levels twenty-four hours a day, compliance with Health Department

operating standards, reduced burden on operating staff, and a reduction of chemical

usage and costs. The CAT 4000 controller and POOLCOMM water quality

management website together provide unprecedented control, access and

documentation.

manually versus automatically with the CAT 4000 controller:
