For fertiliser dosing, choose between the options:
- Flow Rate control (proportionality):
Dosing will be regulated depending on the % value entered as the setpoint value, representing the
percentage of product flow rate dosed with respect to the main water pipe flow rate.
- EC control:
Dosing will be regulated automatically to adjust the conductivity reading to the value entered as the EC
setpoint.
- EC control with flow rate adjustment:
Activate the EC control and set the PEC value (%) in the PI Control menu to set an initial proportionality
value that the controller will regulate automatically to adjust to the EC setpoint.
For acid or base dosing for pH regulation:
- Control in pH:
Dosing will be regulated automatically to adjust the pH reading to the value entered as the pH setpoint.
