The starting routine of the ’servitec’ is automatically called up when the
control is switched on for the first time. ’servitec’ type, for instance ’ser-
vitec magcontrol’ or ’servitec levelcontrol’ will then appear in the display.
Now press ok to get to the language selection:
Select the language by means of the country's symbols,
e.g. GB for the english language and confirm with ok.
The note to read these operating instructions will appear.
Confirm with ok.
This display appears only with ’servitec magcontrol’. Set the
minimum operating pressure according to the static head of your
system (refer also to the following diagram) and confirm with ok.

The starting routine commences when the control is switched on for the first time. It serves for the setting of the
parameters required for the operation of ’servitec’. Should you have entered an incorrect value you can restart the
starting routine by pressing the „quit“ button.
Note:
The starting routine can be run through only once, once this has been done parameter modifications and
cheques have to be performed in the customer menu (→ p. 16).
