The Sensor (SA Bus) port on the middle left side of the controller (Figure 1) is an RJ-12, 6-position modular jack that provides a connection for the Bluetooth® Commissioning Converter, the VAV Balancing Tool, specified network sensors, or other SA Bus devices with RJ-12 plugs.
The Sensor port is connected internally to the SA bus terminal block. See Table 1 for more information. The Sensor Port pin assignment is shown in Figure 2.
