Operating modes
The program sequencer has three operating
modes:
• Automatic
• Service (maintenance)
• Programming
Automatic
In the »automatic« mode, the cleaning functi-
ons are executed using the parameters set in
the »programming« mode. A manual cleaning
cycle can be started at any time independent
of the starting times programmed while no cle-
aning cycle is in progress.
Service
Switching the unit to the »service« mode inter-
rupts automatic operation. The pH electrode
is moved to the »service« position. In service
mode, you can perform manual water rinse
and cleaning operations.
Note:
Once it has been started, a cleaning
cycle (automatic, manual or exter-
nal) is executed completely and can-
not be interrupted. For this reason,
the unit cannot be switched to the
»service« mode during an ongoing
cleaning cycle.
