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.
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.
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.
Installation
Observe the following guidelines and see the
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.
Mounting section in this document.
• Transport the WRS-TTx in the original
container to minimize vibration and shock
damage to the WRS-TTx.
• Verify that all parts are shipped with the WRS-
TTx.
• Do not drop the WRS-TTx or subject it to
physical shock.
• Other than the mounting base, do not open
the WRS-TTx. The WRS-TTx has no userserviceable parts inside.
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.

IMPORTANT: Before specifying the
WRS Series RF Wireless Room Temperature
Sensing System for plenum applications, verify
acceptance of exposed plastic materials in
plenum areas with the local building authority.
Building codes for plenum requirements vary by
location. Some local building authorities accept
compliance to UL 1995, Heating and Cooling
Equipment, while others use different acceptance
criteria.
IMPORTANT: Use this WRS Series
RF Wireless Room Temperature Sensing System
only to provide an input to equipment under
normal operating conditions. Where failure or
malfunction of the sensing system could lead to
personal injury or property damage to the
controlled equipment or other property, additional
precautions must be designed into the control
system. Incorporate and maintain other devices
such as supervisory or alarm systems or safety
or limit controls intended to warn of, or protect
against, failure or malfunction of the sensing
system.

Mounting
Hardware is included with each component of the
WRS Series RF Wireless Temperature Sensing
System, allowing for a variety of mounting scenarios.
The preferred mounting method for the transmitter
uses the two expandable wall anchors included with
the unit. Double-sided adhesive foam tape is also
provided with each transmitter for installations where
building retention and its historical preservation are
important, or in buildings featuring marble, granite,
glass, mirrored, wood veneer, or other decorative
surfaces.
Transmitter Location Considerations
Consider the following guidelines when selecting a
mounting location for the WRS-TTx Series
RF Wireless Temperature and Set Point Transmitter:
• Locate the transmitter so that it is easily
accessible.
• Locate the transmitter on the same floor.
(Mounting one floor above or one floor below the
receiver may work, but will dramatically reduce the
RF signal range.)
• Locate the transmitter on an inside wall away from
water pipes and air ducts, minimally 54 in. (1.4 m)
above the floor level, in an area that accurately
represents the temperature of the controlled
space.
• If possible, locate the tra nsmitter in the line of sight
with the receiver, to minimize signal transmission
loss.
• Check that there are no metal objects (including
equipment rooms and elevator shafts) blocking the
RF transmission signal from the transmitter to the
receiver.
• Do not mount the transmitt er in recessed areas, in
shelving units or metal enclosures, or behind
curtains or doors.
• Do not mount the transmitt er in areas that are
exposed to direct sunlight or condensation, or in
areas that are in close proximity to various heat
sources.
• Do not mount the transmitt er in areas susceptible
to warm or cool drafts such as lobbies, walkways,
or near a bank of computers.
• Do not mount the transmitter less than 2 ft (0.6 m)
from the receiver.
• The distance between two or more transmitter
mounting locations is irrelevant.
Removing the Transmitter from its Mounting Base
The WRS-TTx Series Transmitter ships from the
factory pre-assembled to its mounting base. In order to
secure the assembly to a surface, the transmitter must
first be removed from its mounting base (as illustrated
in Figure 2).

damage the mounting base and the mounting
surface.
6. View the Property Code and Transmitter ID DIP
switch arrays on the back of the transmitter.
For a One-to-One application, set the Property
Code DIP switch array to all “Zeros.” Set the
address portion of the Transmitter ID DIP switch
array to match the corresponding TE-78XX
receiver DIP switch array.
For a Many-to-One application, set the Property
Code DIP switch array (1 to 31) and the address
portion of the Transmitter ID DIP switch array (1 to
511) to desired addresses for the designated
locations. (A “zero” setting is not allowed.) These
addresses will be downloaded via the NAE to a
WRS-RTN and be linked with specific Controllers.
See the Setup and Adjustments section for more
details.
7. Install the batteries into the battery compartment
located on the back of the transmitter, and set the
power DIP switch (top DIP switch on the
Transmitter ID DIP switch array) to the ON
position.

Surface Mounting the Transmitter Using Three
Strips of Double-Sided Adhesive Foam Tape
Each WRS-TTx Series Transmitter includes three
1/16 in. (2 mm) thick, 3/4 x 1 in. (19 x 25 mm) strips of
double-sided adhesive foam tape for mounting
locations where building retention and its historical
preservation are important, or in buildings featuring
marble, granite, glass, mirrored, wood veneer, or other
decorative surfaces. To surface mount the transmitter
using the three strips of foam tape, proceed as follows:
1. Remove the transmitter from its mounting base (as
illustrated in Figure 2).
2. Clean the mounting surface to ensure that the
foam tape holds the mounting base securely to the
surface.
Note: The application temperature must be at
least 50°F (10°C).
3. Peel and stick one side of the foam tape strips to
the smooth surface of the mounting base,
arranged as illustrated in Figure 4.

Repairs and Replacement
If the WRS-TTx Series RF Wireless Temperature and
Set Point Transmitter, or the TE-7720 or
TE-7730 Series RF Receiver, or the WRS-RTN Series
RF Receiver fails to operate within its specifications,
unit replacement is required. For a replacement
transmitter or receiver, contact the nearest
Johnson Controls representative.
Table 2 includes the only replacement parts available
for the WRS Series RF Wireless Room Temperature
Sensing System. Do not attempt any repairs on the
temperature sensing system other than those related
to the replacement parts included in Table 2.
Note: The printed circuit board used with the
WRS Series RF Wireless Room Temperature Sensing
System is retained with a tamper-resistant mechanism.
Removing the printed circuit board from the plastic
housing voids the product warranty.
Replacing the Transmitter Battery
The life of the 1.5-volt AA Alkaline batteries included
with each WRS-TTx Series Transmitter is typically five
or more years. The transmitter communicates
diagnostic data, including battery condition,
approximately every 60 seconds to the receiver, where
it is converted into the appropriate units and electrical
format to warn supervisory equipment (via the
Johnson Controls digital controller) when the batteries
needs to be replaced.
For the WRS-RTN Series Receiver, a low battery
signal is sent to the NAE via the Ethernet trunk, and
this signal is not cleared until the transmitter battery is
replaced. For the TE-7820 Series Receiver, a low

adjustment tool (T-4000-119; ordered separately)
to secure the transmitter to the mounting base.
Note: Once installed, the transmitter and
mounting base assembly cannot be removed from
the mounting surface without first loosening the
tamper-proof transmitter cover holding screw and
then depressing the tab at the top through the slot

battery signal is sent to the digital controller via the
zone bus link, and this signal is not cleared until the
transmitter battery is replaced.
For the TE-7830 Series Receiver, the low battery relay
binary output is turned off for 1 minute every 48 hours
and then back on again. This function is intended to
retrigger a system alarm that may have been
acknowledged without taking appropriate action to
replace the transmitter battery.
See Figure 2 to remove the transmitter from its
mounting base and access the battery for
replacement. Replacement batteries must be
purchased locally; suitable models include any good
quality Alkaline (1.5V) or Lithium (1.6V) AA cells. Do
not use Carbon/Zinc batteries as these will give a poor
life and could give erratic operation.
