Power On Display
At power on, the controller displays the pH feed mode and firmware version number. The pH feed
mode is displayed on the pH channel LED display:
A: Acid feed selected.
b: Base feed selected.
The firmware version number is displayed on the ORP channel LED display:
Firmware version number (or later).
Entering Advanced Setup Mode
Find the Hidden Button (#1) located behind the large pH text over the pH digital display.
1. Press and hold the Hidden Button (#1) for five seconds to enter advanced setup mode.
2. Press the Up (#6) and Down (#7) arrow buttons to scroll through programming options.
3. Press the Enter Button (#8) to make a selection.
P.Fd (pH Feed Mode)
Selects the condition under which the pH feed output is activated.
A: Acid (default). pH feed output is activated when the measured pH is greater than the pH
setpoint, indicating the need to feed acid to decrease the pH of the water.
b: Base. pH feed output is activated when the measured pH is less than the pH setpoint,
indicating the need to feed base to increase the pH of the water.
P.Pr (pH Priority)
Inhibits ORP feed when pH is not within .2 of setpoint.
Off: The pH feed and ORP feed decisions are independent of each other. This is the default
setting.
On: The pH Priority feature is enabled. Inhibits the ORP feed output when the measured pH
value differs from the pH setpoint by more than 0.2 pH units. For example, when the pH set-
point is 7.5, then the ORP feed output will be enabled when the measured pH value is in the
range 7.3 to 7.7; and inhibited when the measured pH is any value outside this range.
P.Ai (pH Interlock)
Inhibits ORP feed when the controller is in pH High Alarm.
OFF: The pH feed and ORP feed decisions are independent of each other. This is the default
selection.
On: The pH Priority feature is enabled. Inhibits the ORP feed output when the pH High Alarm is
triggered. ORP feed will resume when pH High Alarm stops.
