Circulation control
If a biocide dosing is pending on the weekly timer, the 'Biocide dosing' flag (orange LED)
is set. If there is no startup message for the circulating pump (release) is shown, the
'Circulation' flag (grey LED) is set. You can also see that this element is not available by
the white cross against an orange background. At the same time an output is activated,
which is to start the circulation pump.
If you now see a run message for the circulating pump (release), there is a wait of a set
time (precirculation time) to ensure proper reasonable mixing in the cooling circuit.
'Precirculation' is displayed for that time.
Depending on the size of the current conductivity, the next step is either predesalination
or biocide dosing.
After the set dosing time has elapsed, the biocide dosing flag (orange LED) is reset and
the application time starts.
After completion of the exposure time, the 'Circulation' flag (grey LED) is reset and the
output for the circulation pump is deactivated again.
Settings for W, W +, Ws, dosing time, exposure time, precirculation time and dosage time,

Monitoring
Desalination monitoring
If the desalination process is not completed after the start of the desalination beyond an
adjustable time, the display shows 'desalination alarm.'
Signal monitoring
If a biocide dosing is pending but the enable signal is missing, there is a wait of a set time.
If after this time there is still no release, there is an 'Enable signal alert' .
For desalination monitoring and signal monitoring settings, see
Ä Chapter 10.3.2 'Versatronic cooling water' on page 141.
