feed mode has been activated. Calibrating pH Readings from the CAT 2000 are far more accurate than those obtained from most liquid test standards. To match manual water testing results or compensate for a depleted or unclean pH sensor, the pH channel of the controller may be calibrated as follows - Hayward CAT-2000 | CAT 2000 - Page 14
pH control level. 3. The controller will automatically return to the normal operating mode after twenty seconds, storing any changes. Changing the ORP Setpoint The CAT 2000 is preset from the factory to maintain ORP at 650 mV. This is the generally accepted world standard for safe drinking water - Hayward CAT-2000 | CAT 2000 - Page 15
The CAT 2000 features an advanced proportional feed algorithm which constantly analyzes demand for chemicals and initiates feeding in intervals based on the relationship between setpoint and actual water sample values. This feature is highly valuable in maintaining precise control of water chemistry - Hayward CAT-2000 | CAT 2000 - Page 16
