Page 4: General Description
Product description 1. GENERAL DESCRIPTION Green is a high-precision pH, conductivity and proportional dosing controller that at the same time is simple to install and operate. It is specially designed for processes such as fertigation, where correction of pH and EC is needed. The WTR controller enables monitoring of flow, pH and EC, as well as their adjustment through analogue and digital control outputs for dosing pumps. -

Page 7: Setpoint Configuration
Configuration 4.2 Setpoint configuration Configuration of the desired EC, pH or % values for the two channels for control through values or setpoints. Choose the control parameter for channel 1 between dosing by EC setpoint (mS) or by proportionality value (%) of the product to be dosed with the irrigation water. Parameter selection is performed by activating the control through the selected parameter’s Control menu. -

Page 12: Alarms
Configuration - Ki: Integral PI adjustment. This parameter acts on the accumulated error and enables reading stabilisation once the setpoint value has been achieved. It is only valid for in-line controls. For recirculating controls it must be Ki=0. - T delay (seconds): T delay is the time between two consecutive controller orders to position the regulating output. -
