Control point 1:
For measured values <
control point 1, the dosing is 100% base.
Control point 2:
For measured values >
control point 2, the dosing is 100% acid.

Controller simulation
Options
• On
• Off
Factory setting
Off
Here, you can switch a configuration loop on or
off. Hold is taken away when controller
simulation is activated.
Simulation on:
The characteristic values
entered in the previous field are used in the
next field for simulating the controller behavior.
Off:
Controller simulation is exited when you
confirm with
F
.
