Wireless Temperature and Humidity Transmitter Overview and Indentication
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 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 to 8 years.

Installation and Operating Instructions

Analog Output Module Training
The installation process requires that each transmitter is trained to its associated output modules so that they communicate with each other. Pushing buttons in a dened 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 identication mark on the transmitter and associated output modules after they have been trained so that they can be matched together at the job site.
The temperature and humidity variables each require a separate output module. 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 OR HUMIDITY VARIABLE TRAINING
1. To train an output module to a temperature or humidity variable, select the
Resistance, Voltage or Current Output Module calibrated to the proper temperature or humidity range and connect it to the wireless receiver. Note: Multiple output modules can be trained to the same variable if desired.
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 3. Or open the cover of the BAPI-Box on non-room transmitters and remove the battery tabs or install the batteries as shown in Fig 4. The “transmit LED” will ash about once every 20 seconds, indicating a transmission. (The ash is very quick.)
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 3 & Fig 4) on the transmitter. When the output module receives the “training transmission” from the transmitter, the output module’s red 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.
Note: Combination transmitters send both the temperature and humidity information when the “Training Button” is pressed.
However, each Analog Output Module is congured at the time of order as a temperature, humidity, setpoint or override module and will only recognize the relevant data and will ignore the rest.
5.
Mount the transmitter at the desired location, removing the batteries if needed. (The units will remain trained to one another through power failures and battery replacement.)
Battery polarity is important or damage to the unit may occur

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.
