Sensor port
The Sensor (SA Bus) port on the bottom of the controller is an RJ-12, 6-position modular jack that
provides a connection for MAP Gateway, the Bluetooth
®
Commissioning Converter (BTCVT), the VAV
Balancing Tool, specified network sensors, or other SA Bus devices with RJ-12 plugs.
A DIS1710 Local Controller Display also can be connected to the SA Bus port.
The Sensor port is connected internally to the SA bus terminal block. For more information about
the Sensor port functions, requirements and ratings, see Table 5. The Sensor Port pin assignment is
shown in Figure 6.
Note:
The MAP Gateway serves as a replacement for the BTCVT, which is no longer available
for purchase, but continues to be supported.
Supply power terminal block
The 24 VAC supply power terminal block is a gray, removable, 3-terminal plug that fits into a board-
mounted jack on the top right of the controller.
Wire the 24 VAC supply power wires from the transformer to the HOT and COM terminals on the
terminal plug as shown in Figure 7. Do not use the middle terminal on the supply power terminal
block. See Table 5 for more information about the Supply Power Terminal Block.

Note:
The supply power wire colors may be different on transformers from other
manufacturers. Refer to the transformer manufacturer’s instructions and the project
installation drawings for wiring details.
Important:
Connect 24 VAC supply power to the controller and all other network devices so
that transformer phasing is uniform across the network devices. Powering network devices
with uniform 24 VAC supply power phasing reduces noise, interference, and ground loop
problems. The controller does not require an earth ground connection.
