Response to EC pre-blending alarm

The action that you want the controller to take when an EC or pH alarm is triggered:

Pause: Pause irrigation
Continue: Continue irrigation with fresh water (without drain water).

Gain of EC pre-blending 0 - 1000

The factor that determines how many seconds the mixer valve must be actuated, if a
difference arises between the calculated EC setpoint and the measured EC.

EC pre-blending differential time 0 - 1000 sec.

0: The differentiation time is disabled. This mode will suffice in nearly all cases.

1 -> 300: In the case of a mixer valve: The degree to which the control pulse of the
mixer valve will be attenuated.

Maximum control percentage of EC pre-blending 0 - 100 %

1 -> 99: The percentage of the total run time that the mixer valve will be actuated.

100: Maximum control percentage EC has no influence.

No: Not active.

Yes: Active.

pH setpoint 0 - 9.9.

The pH value that the controller will aim to reach. This pH setpoint applies to all
valves of the relevant valve group.
