5.4.2 Wired Room Units - QAA75 set up
Using the Room unit itself, enter “Commissioning mode” (see section on user levels) and
select “Operator section” Use the following parameter lines to define the setup of this room
unit:
The following example illustrates applications available using the settings “Defined as”
(operating line 40) together with “Heating circuit assignment” (operating lines 42 to 48).
Existing heating circuits 1 and 2 are controlled centrally from room unit 1 for logistical
reasons. The room temperature sensor in room unit 1 is relevant to heating circuit 1 only
since climatic conditions for heating circuit 2 may differ from heating circuit 1. Room unit 2
allows for separate temperature measurements and individually setting of heating circuit 2.
However, operating the occupancy button of unit 1 will activate all heat circuits.
