Appendix C–Wireless TEC Commissioning and
Balancing
Once the WRS is bound to a RSX device that is connected to a powered TEC, the TEC itself can be
configured (such as during typical TEC commissioning and balancing procedures) using a tool (such as
WCIS). The tool is simply run (at 1200 baud) on a computer (usually a laptop) connected via an HMI cable
to the WRS HMI port, and can command and read points at the TEC wirelessly. This allows the tool user to
avoid having to access the TEC (typically in the ceiling) to plug into the TEC's RTS port.
Tool communication through the WRS/RSX wireless link is slower (by up to 50%)
compared to a direct connection to the TEC's RTS port.
Appendix D– Wireless Channels
This appendix provides details on wireless link channels and the Wireless Room Sensor Solution.

Overview

For the WRS/RSX pair, the wireless link channel setting is made automatically. By default, the WRS/RSX
pair initially use Channel 15 for the wireless link. When excessive interference is detected on the active
channel, the RSX initiates an automatic change to a new channel.
Channels correspond to the sixteen IEEE 802.15.4 frequency channels in the 2.4 GHz band (Table 13).
