To Change The pH Control Mode:
The CAT 4000 is programmed at the factory to operate in the acid feed mode by default (when
pH exceeds setpoint, the pH chemical feeder is activated). If the sanitizer or other factors of the
application cause the pH to decrease, base feed mode must be selected. From the Configuration
Setup Menu:
Press DOWN to find the pH Control Mode menu item.
Press ENTER to select pH Control Mode.
The current pH Control Mode will be displayed:
Press UP or DOWN to select acid feed or base feed.
Press ENTER to save your selection.
Press MENU to return to the Operating Menu.
The controller will automatically return to normal operating mode in 10 seconds.
NOTE: In certain unusual applications, pH correction may be required in both acid feed and base
feed modes. The third relay can be programmed as described later in this manual to accommodate
this requirement.
pH Priority:
The CAT 4000 features a pH Priority setting which will inhibit ORP feed whenever pH is greater
than .2 pH from the setpoint. This feature provides an important safeguard when sanitizers with a
high pH (such as liquid chlorine) are used. From the Configuration Setup Menu:
Press DOWN to find the pH Priority menu item.
Press ENTER to select pH Priority.
The current pH Priority Mode will be displayed:
Press UP or DOWN to enable or disable pH Priority.
Press ENTER to save your selection.
Press MENU to return to the Operating Menu.
The controller will automatically return to normal operating mode in 10 seconds.
