Ph Set Point - Zodiac TRiPRO Notice De Montage

19. Once the calibration is completed, note the new pH value displayed ('CURRENT pH'). If the value is
different than 7,5 pH, repeat steps 1 to 8.
20. Press (MENU) button twice or wait 30 seconds, the TRi power pack will return to the default display
on the LCD screen.
IMPORTANT NOTES :
- In order to ensure that the Zodiac TRi remains fully efficient, it is recommended to perform a
calibration at least once every two months during the season of pool use.
- Ensure that the pH sensor is perfectly clean before starting a calibration operation (Refer to
chapter 8 / 'pH & ACL sensors cleaning'). Then rinse it with clear water, this will ensure that the
calibration will be more accurate.

4.2/ pH set point

The pH set point is the value to which the Zodiac TRi will adjust the pH in the swimming pool water. This
value is always displayed on the LCD screen. The default setting for the TRi PRO module is 7,2 pH. This
value corresponds to the ideal compromise so as to achieve optimal efficiency in terms of water
disinfection, but it can be changed to adapt to specific pool conditions and requirements.
To change the pH set point :
1. Ensure that the pH sensor has been calibrated (see above procedure).
2. From the default display on the LCD screen, press the (MENU) button.
3. Use the (UP)/(DOWN) buttons to display 'pH/ACL SETUP', then press (SELECT).
4. Use the (UP)/(DOWN) buttons to display 'pH SETPOINT', then press (SELECT).
5. Use the (UP)/(DOWN) buttons in order to change the set point value and press (SELECT) to validate.
6. Press (MENU) button 2 times or wait 30 seconds for the TRi power pack to return to the default
display on the LCD screen.
