Application
The TE-7800 Series Receivers for One-to-One
wireless room temperature sensing systems receive
wireless Radio Frequency (RF) temperature data from
WRS Series Wireless Room Temperature Sensors,
and provide single zone temperature control data to
specified digital controllers in building Heating,
Ventilating, and Air Conditioning (HVAC) systems.
In a typical application, one WRS Series Sensor
reports to one TE-7800 Series Receiver; however, up
to four WRS Series Sensors can associate to a single
TE-7800 Series Receiver. In multi-sensor applications,
the receiver either averages the sensors’ temperature
input or selects the highest or lowest sensed
temperature for control of the target zone.
The TE-7820-x Series Receivers communicate over
a zone bus interface with Johnson Controls®
VMA14 Series Controllers. The receiver supplies the
sensed zone temperature, temperature setpoint, field
strength measurements, and low battery conditions.
The TE-7830-x Series Receivers communicate over
an analog interface with Johnson Controls AS-AHU,
AS-UNT, AS-VAV, DX-9100, and FXxx Series Field
Controllers. The TE-7830-x Series Receivers
communicate 0 to 5 VDC analog signals for zone
temperature and setpoint, binary inputs for low battery
indication, and occupancy status to the supported fie ld
controllers.
Note: TE-78x0-1 Series Receivers (CE Mark
compliant models) have a reduced transmission power
(10 dBm) and transmission range to comply with the
requirements of select countries.
Refer to the TE-7800 Series One-to-One Wireless
Room Temperature Sensing System Technical Bulletin
(LIT-12011097) for information on commissioning TE-
7800 Series Receivers and configuring One-to-One
wireless temperature sensing systems.
Part No. 24-10139-8, Rev. G
Issued February 2016
The TE-7800 Series Receivers use direct-sequence,
spread-spectrum RF technology and operate on the
2.4 GHz Industrial, Scientific, Medical (ISM) band. The
receiver meets the IEEE 802.15.4 standard for low
power, low duty cycle RF transmitting systems.
A TE-7800 Series Receiver operates as a transceiver
to create a bidirectional association with a WRS Series
Sensor that allows the temperature sensing system to
confirm and synchronize data transmissions between
the sensor and the receiver.
IMPORTANT: The TE-7800 Series Receiver is
intended to provide an input to equipment under
normal operating conditions. Where failure or
malfunction of the receiver 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 receiver.
IMPORTANT: Le TE-7800 Series Receiver est
destiné à transmettre des données entrantes à un
équipement dans des conditions normales de
fonctionnement. Lorsqu'une défaillance ou un
dysfonctionnement du receiver risque de provoquer
des blessures ou d'endommager l'équipement
contrôlé ou un autre équipement, la conception du
système de contrôle doit intégrer des dispositifs de
protection supplémentaires. Veiller dans ce cas à
intégrer de façon permanente d'autres dispositifs,
tels que des systèmes de supervision ou d'alarme,
ou des dispositifs de sécurité ou de limitation, ayant
une fonction d'avertissement ou de protection en
cas de défaillance ou de dysfonctionnement du
receiver.
IMPORTANT: The TE-7800 Series Receivers are
not designed or intended for use in mission-critical
or life/safety applications.

Installation
IMPORTANT: Before installing the TE-7800 Series
Receivers in 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.
Follow these guidelines:
• Transport the TE-7800 Series Receivers in the
original container to minimize vibration and shock
damage to the receiver.
• Verify that all the parts shipped with the receiver.
• Do not drop the receiver or subject it to physical
shock.
Parts Included
• one TE-7800 Series Receiver
• one omnidirectional indoor antenna
• one control interface and power cable
• four No. 6 pan-head, sheet-metal screws
Mounting
Location Considerations
Receivers Using the Omnidirectional Indoor Antenna
Follow these guidelines when locating a TE7800 Series Receiver using the omnidirectional
antenna.
• Locate the receiver so that it is easily accessible
(typically just above the ceiling tiles) and within
close proximity to the field controller when using
the 6 ft (1.8 m) power and zone bus interface cable
included with the receiver.
Note: Additional communication cables of
various lengths are available to connect the
(TE-7820-x Series) zone bus only (no power
cable). See Table 1 for details.
• The TE-7820-x Series Receivers may be
located up to 300 ft (91 m) from the
VMA14 Series Controller.
•The TE-7830-x Series Receivers may be
located up to 100 ft (30 m) from the supported
field controller.

associated sensor layout in multi-sensor
applications.
• Locate the receiver on the same floor or building
level as the associated sensors. (Transmissions
may pass through floors. Test the transmission
strength before installing associated sensors and
receivers on different floors or building levels.)
• Locate the receiver in line-of-sight with the sensors
whenever possible.
• Mount the receiver in any orientation. For best
signal transmission, the antenna should be
oriented vertically, and at least 2 in. (50 mm) of the
tip of the antenna should be exposed below or
beyond any pipes, duct work, or other metal
obstructions in direct line-of-sight to the sensors.
• Avoid metal obstructions (including equipment
rooms and elevator shafts) and concrete/brick
walls between the receiver and sensors.
• Mount the receiver in metal enclosures, only if you
take special measures for the omnidirectional
antenna to protrude from the metal enclosure.
You can also use the WRS-SST Series Wireless
Sensing System Tool to determine the RF signal
strength between the sensor and receiver locations.
Refer to the WRS-SST Series Wireless Sensing
System Tools Technical Bulletin
(Part No. 24-10139-16) for more informatio n on testing
RF signal strength in your One-to-One application.
Mounting the Base
The TE-7800 Series Receivers can be surface
mounted using the four No. 6 self-tapping, pan-head
screws.
To mount the receiver base with screws:
1. Remove the receiver from the mounting base
(Figure 2).
2. Use the mounting base as a screw hole template;
place the mounting base against the mounting
surface and mark the location for the four screw
holes (Figure 2).
3. Drill a pilot hole at the four marked locations.
4. Secure the mounting base to the surface with the
(four) No. 6 screws supplied (Figure 2).
• Do not mount the receiver in recessed areas or
shelving units.
Wireless RF Signal Transmission Considerations
The maximum transmission range for indoor
line-of-sight transmissions between a WRS-TTx-00000 Series Sensor and a TE-78x0-0 Series Receiver is
500 ft (152 m). Taking into consideration RF signal
absorption and reflection due to metal objects, walls,
and furniture found in typical building interiors, the
practical average indoor (line-of-sight) transmission
range between a sensor and receiver is 200 ft (61 m).
The maximum transmission range for indoor
line-of-sight transmissions between a WRS-TTx-00001 Series Sensor and a TE-78x0-1 Series Receiver is
375 ft (114 m). Taking into consideration RF signal
absorption and reflection due to metal objects, walls,
and furniture found in typical building interiors, the
practical average indoor (line-of-sight) transmission
range between a sensor and receiver is 165 ft (50 m).
The RF signal strength between an installed sensor
and receiver can be tested by pressing and releasing
the occupancy button on the WRS Series Sensor.
Refer to the TE-7800 Series One-to-One Wireless
Room Temperature Sensing System T e ch nical Bulletin
(LIT-1201 1097) for more information on determining
the signal strength between a WRS Series Sensor and
a TE-7800 Series Receiver.
IMPORTANT: Do not overtighten the mounting
screws. Overtightening the mounting screws may
damage the mounting base or mounting surface.
