Wireless TEC Room Temperature Sensor (Mesh)

CAUTION:

Equipment damage or loss of
data may occur if you do not
follow a procedure as
specified.

Product Description

The APOGEE® Wireless Room Temperature
Sensors eliminate the need to run wire between the
Terminal Equipment Controllers (TECs) and their
respective room temperature sensor. The sensors
communicate with the Field Level Network
Transceivers (FLNXs), mounted at the TECs, that
also support the Wireless Field Level Network
(WFLN).

Caution Notations

Prerequisite

All wiring must conform to NEC and local codes and
regulations.

CAUTION:

Do not mount the WRTS within 3 feet of
other RF devices such as microwave
ovens, Wi-Fi/802.11 access points, etc.

CAUTION:
If a WRTS cannot communicate with its

FLNX for an extended period of time due
to the WFLN not being commissioned or
the FLNX is out of range, remove the
battery to avoid excessive battery drain.

CAUTION:
Over-tightening may cause the sensor

base plate to crack or bend.

Mounting Information

WRTS Installation

1. Select a location for the WRTS, following the
standard rules for room temperature sensor
placement. Locate the WRTS no further than
100 feet from the nearest FLNX on its WFLN,
ideally in a location where there are no major
RF obstructions (for example, metal or concrete
walls) between the two.

2. Remove the plastic insulating strip between the
battery in the WRTS battery holder (or insert
the battery) to power-up the WRTS.

NOTE: Even though the WRTS is now

powered, it will stay in a low-power
sleep mode until commissioned.

If the WRTS has an LCD panel, the
displayed value will not change until
the WRTS is bound to an FLNX/TEC.

3. Mount the WRTS base plate to the wall.

4. Snap the sensor front to the sensor base plate

by first hooking the sensor front to the top
latches, and then rotating the cover downward
until it latches.

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 proper airflow and
the front cover removal tool.

Away from drafts caused by doors, windows,

outside walls, air registers, return air plenums,
etc.

Away from heat sources such as strong lights,

fireplaces, direct sunlight, etc.

On an inside wall, about 5 feet (1.5 m) above

the finished floor.

The line of sight distance (through walls) to the

nearest FLNX ideally should be less than 100
feet (30 m).

Drywall Base-Plate Mounting (Figure 2)

1. Using the sensor base plate as a template, mark
the top and bottom mounting hole locations for
drywall mounting.

2. Drill two 3/16-inch (4.8 mm) mounting holes and
mount the two wall anchors.

3. Orient the UP arrow on the base plate at the top
and mount on the wall as follows:

a. Level the sensor base plate.
b. Tighten the two mounting screws to the

sensor base plate.

5. Loosen the safety set screw at the bottom of the
base one or two revolutions to lock the cover to
the base. Be careful not to loosen too far as the
screw can be completely removed from the base.

NOTE: There is a perforated label containing

the 16-digit EUID number on the back
of the WRTS. It can be removed and
used for wireless communications with
the WRTS via the TLX.

6. Commission per the WFLN Start-up Procedure

(140-0649)

Always mount the sensor vertically. Locate the

sensor as follows:

Per design specifications, and local regulations.

Section 7.1.5 of RSS-GEN

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.

FCC NOTE:

This device complies with Part 15 of the FCC rules.
Changes or modifications not expressly approved by
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.

FCC Interference Statement
Part 15.105 (b)

This equipment has been tested and found to
comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC Rules. These limits
are designed to provide reasonable protection
against harmful interference in a residential
installation. This equipment generates uses and can
radiate radio frequency energy and, if not installed
and used in accordance with the instructions, may
cause harmful interference to radio communications.
However, there is no guarantee that interference will
not occur in a particular installation. If this equipment
does cause harmful interference to radio or
television reception, which can be determined by
turning the equipment off and on, the user is
encouraged to try to correct the interference by one
of the following measures:

Reorient or relocate the receiving antenna.

Increase the separation between the

equipment and receiver.

Connect the equipment into an outlet on a

circuit different from that to which the
receiver is connected.

Consult the dealer or an experienced

radio/TV technician for help.

Industry Canada Statement per Section

4.0 of RSP-100:

The term “IC:” before the certification/registration

number only signifies that the Industry Canada
technical specifications were met.

This device has been designed to operate with an
antenna having a maximum gain of 5dBi. An
antenna having a higher gain is strictly prohibited
per regulations of Industry Canada. The required
antenna impedance is 50Ω.

To reduce potential radio interference to other users,
the antenna type and its gain should be so chosen
that the equivalent isotropically radiated power
(EIRP) is not more than that required for successful
communication.

The Wireless Room Temperature Sensor (Mesh)
must be installed or replaced by professional
installation personnel only.

電波輻射性電機設備之干擾。

According to "Administrative Regulations on Low
Power Radio Waves Radiated Devices" Without
permission granted by the DGT, any company,
enterprise, or user is not allowed to change
frequency, enhance transmitting power or alter
original characteristic as well as performance to a
approved low power radio-frequency devices. The
low power radio-frequency devices shall not
influence aircraft security and interfere legal
communications; If found, the user shall cease
operating immediately until no interference is
achieved. The said legal communications means
radio communications is operated in compliance
with the Telecommunications Act. The low power
radio-frequency devices must be susceptible with
the interference from legal communications or ISM
radio wave radiated devices.
