Dimensions
1. Remove the cover from the base at the bottom of the device.
2. Position the sensor base vertically on the wall 1.35 m (4.5 ft.) above the oor with the “UP” arrow facing upward. Locate away
from windows, vents and other sources of draft. If possible, do not mount on an external wall, as this may cause inaccurate
temperature readings.

6. Congure the device.
Address Configuration:
Each device on a single network must have a unique address. Set the DIP switch labeled “ADDRESS” to assign a unique address
before the device is connected to the network. If an address is selected that conicts with another device, neither device will be
able to communicate.
Address the device as any whole number between and including 1 to 127. Note that zero is not a valid address for Modbus;
zero is a valid address for BACnet. Positions 1 through 7 of the “ADDRESS” DIP switch designate the address. Position 8 toggles
between the Modbus and BACnet communication protocols, as shown in the diagram below. This is the left bank of DIP
switches on the sensor.
LSBM

124816 32 64
Decimal Values
Modbus/BACnet
Toggle
On = Modbus
O = BACnet
Binary Address
To set an address using the DIP switch, simply add the values of any switches that are in the ON position.
For example, an address of 73 is set as shown in the diagram below.
73
=
LS
BM
SB
124816 32 64
Position number 1 has an ON value of 1, position number 4 has an ON value of 8 and position number 7 has an ON value of 64
(1 + 8 + 64 = 73).
Communications Configuration:
See the Product Diagram section for the location of the DIP switch labeled “CONFIG”. The following parameters are
congurable:
- Parity (Modbus only): None, Odd, None1 (one stop bit), Even
- Baud rate: 9600, 19200, 38400, 57600 (Modbus), 76800 (BACnet)
