pH Range Settings

• There are 2 values to configure, so the system maintains the water pH within the specified range:
  • pH min > pH > pH max
  • In the example shown: pH min = 7.37, pH max = 7.40
  • During operation, when the measured pH exceeds pH max, the system will lower pH by opening the CO₂ valve to inject CO₂. When pH drops below pH min, the CO₂ valve will close.
  • It is recommended not to set pH min/pH max too far apart. In the example, the gap between pH min and pH max is 0.03, which is ideal. A larger gap means greater pH swings and longer CO₂ valve open times. Frequent prolonged valve operation may cause the valve spring to deteriorate faster due to heat generated during operation.
