Setting of setpoints and display of other system values.

Procedure:

•

The symbol line is displayed by turning the dial knob.

•

By turning the dial knob again, the selection cursor
can be placed under the relevant symbol.
If the selection cursor is moved beyond the left or
right positions, the display mode is shown.
The display mode also appears, if the enter key has
not been used for 20 seconds.

•

By pressing the enter key, the relevant symbol is
activated and the value set is flashing in the display.
The other symbols are faded out.

•

The value can be changed by turning the dial knob.

•

The value is confirmed by pressing the enter key and
the selection is exited. All symbols of the symbol line
are displayed again.

If the WTC is controlled remotely (via N1 see Ch.
4.6.4) or if an external controller (WCM-FB and/or
WCM-EM) is connected, the menu points are faded
out as the settings are carried out on the controllers.

If communication fails the symbols for emergency
operation are faded in.
