To reprogram the unit after a reset or battery change, you generally need to calculate the capacity in cubic meters ( ) using this formula:
Capacity (m3)=Liters of Resin (22)×Factor (5)Network Hardness−Residual HardnessCapacity open paren m cubed close paren equals the fraction with numerator Liters of Resin (22) cross Factor (5) and denominator Network Hardness minus Residual Hardness end-fraction Residual Hardness: Usually set between 7∘F7 raised to the composed with power cap F 12∘F12 raised to the composed with power cap F for domestic use.

Set Time: Press the clock button and use arrows to adjust the current local time.
Input Hardness: Use a kit like the Cillit Aquatest to find your water's hardness level, then enter that value into the "Set Hardness" screen.
Regeneration Time: Schedule this for a low-usage period, typically 2:00 AM.
Salt Level: Fill the brine tank about halfway; ensure the salt level stays above the water level for proper brine creation. 💡 Key Maintenance Tips Manuales Descalcificación - Cilit
