Calibrating pH Readings from the HCC 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: Press the pH Setpoint Adjustment Button (#4) twice, illuminating the green "CALIBRATE" LED. Press the arrow-shaped pH Channel Increase Button (#2) or pH Channel Decrease Button (#3) until the digital display matches your manual pH test reading. The controller will automatically return to the normal operating mode after twenty seconds, storing any changes. Changing the pH Setpoint The HCC 2000 is preset from the factory to maintain pH at 7.5. To set pH control at a different level, perform the following: Press the pH Setpoint Adjustment Button (#4) until the green "SET" LED is illuminated. Press the arrow-shaped pH Channel Increase Button (#2) or pH Channel Decrease Button (#3) until the digital display matches your desired pH control level. The controller will automatically return to the normal operating mode after twenty seconds, storing any changes. Changing the ORP Setpoint The HCC 2000 is preset from the factory to maintain ORP at 650 mV. This is the generally accepted world standard for safe drinking water. In order to meet Health Department standards for a particular pool or spa, the ORP setpoint may be changed to maintain a desired sanitizer level by performing the following: Manually test pool or spa to confirm that the current sanitizer reading (chlorine, bromine, etc.) is the level you wish to maintain. Note the ORP reading displayed by the controller. Press the ORP Setpoint Adjustment Button (#8) until the green "SET" LED is illuminated. Press the arrow-shaped ORP Channel Increase Button (#6) or ORP Channel Decrease Button (#7) until the digital display matches the ORP reading previously noted. The controller will automatically return to the normal operating mode after twenty seconds, storing any changes. The ORP setpoint should be changed as needed to maintain sanitizer residuals in conformance with Health Department standards. 9 USE ONLY HAYWARD GENUINE REPLACEMENT PARTS

Calibrating pH
Readings from the HCC 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 sen-
sor, the pH channel of the controller may be calibrated as follows:
Press the
pH Setpoint Adjustment Button
(#4) twice, illuminating the green “CALIBRATE”
LED.
Press the arrow-shaped
pH Channel Increase Button
(#2) or
pH Channel Decrease Button
(#3) until the digital display matches your manual pH test reading.
The controller will automatically return to the normal operating mode after twenty seconds,
storing any changes.
Changing the pH Setpoint
The HCC 2000 is preset from the factory to maintain pH at 7.5.
To set pH control at a different
level, perform the following:
Press the
pH Setpoint Adjustment Button
(#4) until the green “SET” LED is illuminated.
Press the arrow-shaped
pH Channel Increase Button
(#2) or
pH Channel Decrease Button
(#3) until the digital display matches your desired pH control level.
The controller will automatically return to the normal operating mode after twenty seconds,
storing any changes.
Changing the ORP Setpoint
The HCC 2000 is preset from the factory to maintain ORP at 650 mV.
This is the generally ac-
cepted world standard for safe drinking water.
In order to meet Health Department standards for
a
particular pool or spa, the ORP setpoint may be changed to maintain a desired sanitizer level by
performing the following:
Manually test pool or spa to confirm that the current sanitizer reading (chlorine, bromine, etc.)
is the level you wish to maintain.
Note the ORP reading displayed by the controller.
Press the
ORP Setpoint Adjustment Button
(#8) until the green “SET” LED is illuminated.
Press the arrow-shaped
ORP Channel Increase Button
(#6) or
ORP Channel Decrease
Button
(#7) until the digital display matches the ORP reading previously noted.
The controller will automatically return to the normal operating mode after twenty seconds,
storing any changes.
The ORP setpoint should be changed as needed to maintain sanitizer residuals in conformance
with Health Department standards.
