The sensors connected to terminal B1 can be tasked with different functions:
Parameter setting
Description
Room
Room indoor air sensor (can also be used for
averaging, see below).
Return air Return air sensor
(refer also to Section 9.7, "Periodic fan kick")
No sensor
No sensor connected
(basic setting, except for FNC08)
Only measured value
acquisition
Uses the signal, see "analog input B1", page 155.
Supply air (cascade)
(RXB2... only)
Supply air temperature for cascade control.
The sensor is automatically configured as a supply air
sensor if application FNC08 is selected.
The sensor is parameterized under fan control for tool architectural reasons:
Click Fan control, Temperature sensor B1 (see page 121).
Select Fan control, Temperature sensor B1 (see page 121).

7.1.3 Averaging analog input & PPS2 interface
In large spaces it can be useful to measure the room temperature in two locations and
to determine an average value. If both a QAX3… room unit and a QAA24 LG-Ni1000
sensor are connected to a controller, the measured room temperature is automatically
based on the average value from both sensors. The automatic detection feature
prevents miscalculation.
A QAX34 / QAX84 will display this average value.
