2.3.3 Operating Modes
2.3.3.1 Automatic Operation (Standard Operating Mode)
After switching on the main switch, the system is fully automatic controlled through the
electronic control system and the float switch in the drinking water tank. The mode selector
switch is in the “Auto” position.
The control system usually operates in the normal plane in the operating mode operation.
With the exception of an error acknowledgement (only in case of pre-selection Vw-
acknowledgement by actuating the ESC key button), no further operating by the operator is
possible; this is to protect the control system against unintended / unauthorized manipulations.
By entering the respective password, the user level or the technician level for input
of operating parameters, etc. is cleared (see section 3.4.3.1). The program structure
is given in the appendix, Figure 21.
Operating parameters and setting values are listed on the data sheet by the
manufacturer (cf. Tables 34 and 35).
2.3.3.2 Manual Operation
The float switch in the drinking water tank is deactivated by the manual / automatic rotary switch
("Manual" position), so that the plant can run continuously.
Manual operation is not standard operating mode, as the system does not switch off
automatically.
