The commissioning menu is automatically displayed upon PowerUp and must be
processed. The user must enter the language settings and time. Once completed,
the basic display is displayed and the menu no longer appears at PowerUp. It can,
however, be enabled again using the parameter "Commissioning menu" and then
is displayed again the next time power is interrupted.
Addition: The process can be bypassed by pressing the ESC button on the
commissioning menu. The basic display is immediately displayed and the
commissioning menu returns at the next PowerUp (since it has not yet been
processed).

¦ Operator unit 2 ¦ Operator unit 3 ¦ Service unit
* QAA7x only
Basic principle: the number (1, 2, or 3) after the room unit or operator unit indicates
the heating circuit (1, 2, or 3) controlled by the operator unit.
Additional assignments are available for room unit/operator unit 1 on heating
circuits 1 to 3 (heating circuit assignment: Operating lines 42 to 48).

The following example illustrates applications available using the settings "Used
as" (operating line 40) together with "Heating circuit assignment" (operating lines
42 to 48).
Existing heating circuits 1 and 2 should be controlled centrally from room unit 1 for
logistical reasons. The room temperature on room unit 1 is relevant to only heating
circuit 1 since climatic conditions for the heating circuit 2 (e.g. winter garden) may
differ from heating circuit 1. A room unit 2 allows for separate temperature
measurements and individually setting of heating circuit 2. Conversely, operating
unit 1 operates the occupancy button.
Settings for the example:
QAA7x, unit 1
Operating line 40 Room unit 1
Operating line 42 Heating circuits 1 and 2
Operating line 47 For heating circuit 1 only
Operating line 48 For all assigned heating circuits
QAA7x, unit 2
Operating line 40 Room unit 2
