Adaption sequence Each adaption phase is then displayed with a status message:
Various status messages can be output, depending on the selection of
the dosing equipment. Different status messages also have different
execution times. It is possible that several status messages are only
displayed briefly or not at all if the execution time is very short.
CAUTION!
Adaption can take up to 13 hours, depending on the control loop. Du-
ring this time no errors should occur on the control loop (e.g. filter back-
washing, changes in the circulation or widely fluctuating number of vi-
sitors).
NOTE
The adaption procedure can be terminated at any time with "BREAK".
The previously set parameters remain unchanged.
