Service position
In the "Service" position the settings of the device can be
edited by means of the service switch and the control pan-
el.
From the "Service" position, the service switch can be
turned a little further to the "SET" position. From this posi-
tion, the switch returns to the "Service" position after re-
leasing it. The "SET" position merely fulfils a pushbutton
function.
Note
The setting options are described in Chapter 7.4 or 7.24
"Service functions with LED display".
