SECTION 2. CAT 4000 SYSTEM COMPONENTS
The following is a description of the components incorporated in a typical CAT 4000
wireless water quality control system:
The Professional-Series pH Sensor samples water from the filtration system and
sends signals to the controller indicating the acidity of the water. The ideal pH range
for pools and spas is 7.4 - 7.6. The CAT 4000 controller is preset from the factory to
maintain pH 7.5. If pH is maintained below 7.4 (too acidic), eye irritation, corrosion
of equipment, and damage to the pool or spa surface can occur. If pH is maintained
above 7.6 (too alkaline), sanitizer activity is reduced, water may become cloudy, and
eye irritation may result.
The Professional-Series ORP Sensor samples water from the filtration system and
sends signals to the controller indicating the oxidation-reduction potential (redox) of
the water. ORP is an actual measure of sanitizer activity (chlorine, bromine, ozone,
etc.) and bacteriological water quality rather than an expression of chemical
residual levels. The CAT 4000 controller is preset from the factory to maintain ORP
at 650 millivolts.
The Flow Sensor monitors the rate of flow across the pH and ORP sensors and
signals the controller to disable automated chemical feeding during periods when the
filtration system is off or low recirculation flow is detected.
The Flow Cell provides a convenient location for mounting the pH, ORP and Flow
sensors while ensuring ideal hydraulic conditions to maximize sensor performance
and life.
The CAT 4000 Controller scans and interprets the signals from the pH, ORP, flow,
and optional digital flow-rate and level sensors, displays water quality readings and
alarms in alphanumeric format, and activates chemical feeders in proportion to
demand to maintain pH and ORP setpoint levels.
The controller incorporates audible and visual safeguard alarms for out of range
conditions and menu-driven control of setpoints, alarms, and a host of advanced
features. The CAT 4000 controller also features an internal transceiver for wireless
transmission of data between the controller and POOLCOMM website.
The Level Sensors (optional) provide signals to the controller indicating low pH
chemical tank level, low ORP tank level, and low water level.
The Digital Flow Sensor (optional) provides a flow rate to be displayed by the
controller and an alarm indication when filter maintenance is required.
