WRS-TTx Series Radio Frequency (RF)
Wireless Transmitters
Applications
The WRS-TTx Series Wireless Room Temperature
Transmitters are designed to report temperature
and set point (certain models) to a suitable JCI data
receiver. They can be used in two separate types
of control systems, depending on the application.

FCC and Industry Canada Compliance
Compliance Statement (Part 15.19)
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
1. This device may not cause harmful
interference, and
2. This device must accept any interference
received, including interference that may
cause undesired operation.
cause undesired operation.
Warning (Part 15.21)
Changes or modifications not expressly approved by
the party responsible for compliance could void the
user’s authority to operate the equipment.
the party responsible for compliance could void the
user’s authority to operate the equipment.
To comply with FCC’s RF exposure limits for general population
/ uncontrolled exposure, the antenna(s) used for this transmitter
must be installed to provide a separation distance of at least 20
cm from all persons and must not be co-located or operating in
conjunction with any other antenna or transmitter.
Industry Canada Statement
The term “IC” before the certification/registration
number only signifies that the Industry Canada
technical specifications were met.

technical specifications were met.
Locating the Transmitters
The wireless design of the WRS-TTx transmitter
allows a great deal of location flexibility without
worrying about installing wiring. It is important to
follow the standard guidelines for
Sensor/Thermostat location so that the sensor is
sensing the true room temperature. It is important
to avoid outside walls, windows, and areas where
sunshine can fall directly on the sensor or where
drafts from HVAC equipment are likely.

to avoid outside walls, windows, and areas where
sunshine can fall directly on the sensor or where
drafts from HVAC equipment are likely.
Additionally, it is important to remember that the
transmissions used by the WRS-TTx are basically
line-of-site and you should review the likely path of
the RF energy before installation. Generally it is
important to avoid having large areas of metal such
as elevators, duct work, or equipment rooms
between the sensor and the receiver.

An optional signal strength site survey tool receiver
is available to determine the appropriate location of
the WRS Wireless Room Temperature Sensing
System prior to its installation. Using any standard
WRS-TTx transmitter in the rapid transmit mode
(previously described in the section Occupancy
Button and LED), along with the survey tool
receiver TE-7820-100, you can verify that the RF
transmission signal is sufficient to ensure proper
system operation. See Table 1 and refer to the TE-
7820-100 RF Wireless Signal Strength Site Survey
Tool Product Bulletin (LIT-xxxxxxxx) for more
details.
