PIQ control mode for the EC adjustment is a PI algirithm conditioned by the water flow. By means of the PEC parameter the
system set an initial proportional dosage. Later on the controller modifies the dosing flow following a standard PI
adjustment.
PEC=0
Control PI. PIQ disabled.
PEC= 0.01 - 2%
Initial proportional flow in %.
It is necessary to define the clean water EC value (ECo)in the Set UP menu.

The initial proportional value PEC must be introduced for the fertigation program with lower EC set point (The set
points lower han ECo are not considered).
The initial proportional value for the other fertigation programs is odified proportionally to the difference between Set
Point and ECo.
