6.5.12. System capacity
Set the capacity of the tank where the valve is installed.
Note
On the basis of system capacity, safety coefficient and inlet water hardness, the controller
calculates the volume of water that the system can treat between 2 regenerations.
This volume corresponds to the volume the tank could treat if the inlet water hardness is 1°F, 1°TH
or 1°dH.
6.5.13. Safety coefficient
Set the percentage value by which the total capacity is reduced as a safety coefficient.
6.5.14. Inlet water hardness
Set the input water hardness in the unit set on chapter 6.5.11. Display format, page 64.
6.5.15. Trip points setting
Set the flow rate and switching delay when another tank is switched to service.
