Product Description

Wireless Room Sensors eliminate the need to run
wire between Terminal Equipment Controllers
(TECs) and their respective room temperature
sensor. The sensor communicates wirelessly with
the TEC using a Room Sensor Transceiver (RSX)
mounted at the TEC.

Installation Instructions
November 2, 2015

Required Tools

• Phillips screwdrivers, sizes 1 and 2

• Medium and small flat-blade screwdrivers

• 1/16” hex key

• Medium-duty electric drill and 3/16-inch

(4.8 mm) drill bit

• Small level and tape measure

NOTE: Depending on the actual installation

(surface mounting) some of these tools
may not be required.

Binder Instructions

Do not mount the WRS within 10 feet of
other RF devices such as microwave
ovens, Wi-Fi/802.11 access points, and so
on.

1. Remove the plastic insulating strip between the
battery in the WRS battery holder (or insert the
battery) to power up the WRS.

NOTE: Even though the WRS is powered, it

stays in a low-power sleep mode until
commissioned.

Binding Using HMI Commands

To bind your WRS to its associated RSX using HMI
commands, follow these steps:

1. Connect a PC cable (540-143) from a computer
to the RJ-11 port on the bottom of the WRS.

2. Start a HyperTerminal session, log on (1200
baud, 8 data bits, no parity, 1 stop bit, no flow
control), and then press ENTER to display the
WRS prompt.

3. At the WRS HMI prompt, type
BIND RSX a (where a = EUID of the RSX), and
then press ENTER.

When binding is succ ess f ul, the LED on the RSX
turns solid yellow, and the WRS initiates a
communication check with the RSX to verify link
quality.

When successful, remove the computer cable from
the WRS. By default the HMI will time out after five
minutes. Remove and reinsert plug to reactivate.

For additional information on using HMI commands
to change the default configuration, troubleshoot
binding, placement or other diagnostics, see the
Wireless Room Sensor Solution User’s Guide
(563-068).

2. Bind WRS to associated RSX using optional
auto-binding cable (part number 563-207) or
HMI command.

NOTE: Verify associated RSX is installed and

Binding Using Auto-Binding Cable

To bind your WRS to its associated RSX using the
optional auto-binding cable, follow these steps:

1. Using the Auto-binding cable (563-207), plug

2. Plug the other cable connector into the RJ-11

3. If the RSX indicator light does not immediately

When binding is successful, the indicator light on the
RSX turns solid yellow. When successful, remove
the auto-binding cable.

port on the RSX.

turn solid yellow, power cycle the RSX to enter
binding mode.

Mounting Instructions

If the WRS cannot communicate with its
RSX for an extended period of time due to
the RSX not being commissioned or the
RSX is out of range, remove the battery to
avoid excessive battery drain.

1. Select a location for the WRS, following the
standard rules for room temperature sensor
placement.

Always mount the sensor vertically. Locate the
sensor as follows:

• No further than 100 feet (30 m) from the

RSX, ideally in a location where there are no
major RF obstructions (for example, metal or
concrete walls) between the two devices.

• Per design specifications, and local

regulations.

• Where the air circulates around it freely (not

in recessed areas or behind doors).

• Allow a minimum of 4 inches (10 cm) free

space above and below for the front cover
removal tool and to allow proper airflow.
