9. Operation and use
9.1 Basic design of the control unit
Color LCD display (digital):
The conductivity is measured at the cartridge outlet. The water flows through the conductance measuring probe
integrated in the control head or in the connection fitting. The digital electronics built into the control head or in the
conductance measuring device continuously monitor the conductivity.
When the set limiting value is reached, an alarm message is displayed.
Functions of the digital display:
The digital display shows the value in S/cm.

The electronics are powered with 9V DC — the current consumption is less than 200 mA. The 9V DC inlet is protected
against polarity reversal. The maximum permitted voltage via this input is 24V DC. AC voltage is not permitted!
