Wireless Temperature Transmitter Overview and Indentication
The BAPI Wireless Temperature Transmitter measures the room temperature
and transmits the data at 418MHz or 433MHz RF to a receiver. The transmitter is mounted in a BAPI-Stat 2 style enclosure and has maximum in-building
range of open-air range of 100 feet.
The transmit rate is approximately once every 20 seconds with an estimated
battery life of 5 to 8 years using two high-capacity 3.6V lithium batteries. Each
transmitter has a unique address with built-in error detection. Each variable
sent by the transmitter is picked up by the receiver and converted by a separate BAPI Analog Output Module to a voltage, current or resistance signal
which is sent to the controller.

Complete Wireless Temperature and/or Humidity System Overview
418 MHz System:
The Transmitter measures the temperature or
temp/humidity and transmits the data at 418MHz to
the 418 MHz Receiver up to 100 feet away. The optional temperature setpoint and override status are
also transmitted at 418 MHz to the receiver. The
transmit rate is about once every 20 seconds with
an estimated battery life of 5 to 8 years.
The information sent by the Transmitter is picked
up by the 418 MHz Receiver and passed along
to the Analog Output Modules. Each transmitted
variable (temperature, humidity, setpoint, etc.) is
converted by a separate output module into an
analog resistance, voltage, current or relay contact
which is hard wired to the analog inputs of the BAS

900 MHz System:
The Transmitter measures the room temperature or temp/humidity and
transmits the data at
418MHz to a Repeater
up to 100 feet away. The
optional temperature setpoint and override status
are also transmitted at
418 MHz to the Repeater.
The transmit rate is approximately once every
20 seconds with an
estimated battery life of 5

Analog Output Module Training
The installation process requires that each transmitter is trained to its associated output module so that they communicate with each other. Pushing
buttons in a dened sequence on the units will bind them together.
The training process is easiest on a test bench with the units within arm’s
reach of each other. Training can be done in the eld but requires two people
and a set of walkie talkies or cell phones. Be sure to place an identication
mark on the transmitter and associated output module after they have been
trained so that they can be matched together at the job site.
Perform the training sequence for each output module. Any transmitted variable can be trained to more than one output module. If a Repeater is used in
the system, be sure it is powered and within reception range of the transmitter and the 900 MHz Receiver to train the output modules.

TEMPERATURE VARIABLE TRAINING
1. To train an output module to a temperature variable, select the
Resistance, Voltage or Current Output Module calibrated to the proper
temperature range and connect it to the wireless receiver. Note: Multiple
output modules can be trained to the same transmitter.
2. Apply power to the receiver which will supply power to the connected
output modules. The power LED on the receiver will light and remain lit. (Current Output
Modules must have loop power supplied to the module itself before they can be trained.)
3. Remove the cover of the room transmitter and remove the battery tabs or install the batteries,
observing polarity as shown in Fig 4. The “transmit LED” will ash about once every 20 seconds,
indicating a transmission.

4. Press and hold down the “Service Button” on the top of the output module (Fig 5) that you wish
to train. Then, press and release the “training button” (see Fig 4) on the transmitter. When the
output module receives the “training transmission” from the transmitter, the output module’
LED will light steady. Release the “Service Button” on the output module and the red LED will go
out. The transmitter and output module are now trained to each other. During normal operation,
the output module’s LED will ash about once every 20 seconds indicating data reception from
the transmitter trained to it.

5. Mount the transmitter at the desired location, removing the batteries if needed. (The units will remain trained through power failures
and battery replacement.)

Drywall Mounting
1. Place the base plate against the wall where you want to mount the sensor.
Typically 5 feet above the oor.
2. Using a pencil, mark out the two mounting holes.
3. Drill two 3/16” (4.7 mm) holes in the center of each marked mounting hole.
Insert a drywall anchor into each hole.
4. Secure the base to the drywall anchors using the #6 x 1 inch mounting
screws provided.
5. Install provided batteries or pull battery tabs and follow polarity as shown
in gure 3 or damage may occur. The unit will work on just one battery
however the battery life will be cut in half.
6. Attach cover by latching it to the top of the base, rotating the cover down
and snapping it into place.
7. Secure the cover by backing out the lock-down screws using a 1/16” Allen
wrench until they are ush with the bottom of the cover.
