Five screwholes available; use a mini-
mum of two for secure mounting.
INSTALLATION
1. Remove the cover by pressing the tab at the top of the sensor while
pulling outward from the top of the cover.
2. Remove the backplate by unfastening the sensor from the bottom
of the backplate and pivoting the sensor outward.
3. Punch out openings in the backplate.
4. Position the sensor vertically on
the wall, 4 1/2 feet above the
oor.
5. Mount the backplate onto the wall using the screws provided.
6. Wire the backplate.
Wire the RS-485 connections with shielded, twisted-pair wire, such as Belden Cable
1120A or equivalent. With 2-wire cable, connect the shield at one end only to the
RS-485 SHIELD terminal.

DIP switches, located on backside of board,
Top row: Address switches
Bottom row: Conguration switches
Select Address DIP switches
1. Up for Modbus, Down for BACnet.
2. Up to add 64 to network address.
3. Up to add 32 to network address.
4. Up to add 16 to network address.
5. Up to add 8 to network address.
6. Up to add 4 to network address.
7. Up to add 2 to network address.
8. Up to add 1 to network address.
The network address is the sum of the values selected by placing switches 2
through 8 in their UP position. E.g.: If switches are D D D U D U D D, then BACnet
communication is selected, and the address is 16 + 4, for a total of 20. Valid Modbus
addresses are 1 to 127, and valid BACnet addresses are 0 to 127. Each device on the
daisy chain must have a unique address.
Select Configuration DIP switches
Conguration DIP switches 1 and 2 control the parity settings for Modbus and have
no eect on BACnet communication, which never has parity.
Switch 1 Switch 2 Parity
Down Down None (2 stop bits)
Down Up Odd
Up Up Even
Up Down None (1 stop bit; common but non-standard)
Conguration DIP switches 3 and 4 control the data rate for both Modbus and BACnet
modes.
Switch 3 Switch 4 Data Rate
Down Down 9600 bps
Down Up 19200 bps
Up Down 38400 bps
Up Up Modbus: 57600 bps; BACnet: 76800 bps
Ground each unit via the power supply GND terminal or the RS-485 SHIELD terminal
if the power supply is oating. Grounding is necessary to minimize common mode
voltage on the signal lines and to minimize radio frequency emissions that can
interfere with the operation of nearby radio equipment.
Daisy-chain devices with 120Ω termination resistors between RS-485+ and RS-485-
on the last device at each end of the chain. Maximum of 63 devices on one daisy
chain.
7. Congure the sensor.
Set the DIP switches on the backside of the
board.

Modbus Configuration
The list of supported Modbus function codes and the Modbus Point Map are in the
Point Map section of this document. The capabilities for controlling the TWxP are
identical with those for BACnet. The functions are summarized here.
Function Description
Coils Used to set temperature (Fahrenheit scale) and override button coil. *
Discrete
input
Indicates whether the relay is on.
Input
registers
Used to read the sensor options: RH (in units of 0.1%), temperature (in units
of 0.1°), and the slider (in units of %full scale). **
Holding
registers
Used to specify the temperature oset and RH oset. Initial settings are 0°F,
and 0%, respectively. Settings are retained if power is lost.
* The temperature scale is maintained if power is lost. When delivered, temperature in Farenheit
and calibration lockout is on. Pressing the override button turns the override button coil on. It can
only be turned o remotely.
** If any sensor option is not installed, the reading for that sensor will be 0.
The various registers are still present even without the corresponding options
installed. In particular, the discrete input function can be used to see if the CO2
setpoint has been reached even if the relay is not in use.
BACnet Configuration
The list of BACnet objects and their implemented properties is in the BACnet
Descriptions section of this document. The capabilities for controlling the CWxP
are identical with those for the Modbus conguration. However, BACnet has some
additional protocol-related settings.
The Device Object must have a unique name. This is set at the factory to the model
name, followed by the device’s serial number. The name can be changed if desired.
The device object must also have a unique object identier number. By default, this
is 133nnn where nnn is the current network address. This number can be changed
and the new number will be remembered. Setting the number to -1 (normally not
allowed) will reset the device to the default.
The Reliability property of the analog inputs for temperature, relative humidity, and
slider can be read to determine whether the device has these options installed.
8. Install the sensor onto the backplate.
9. When installation is complete, install the cover
and snap into place.
VISUAL INDICATORS
The RX light will ash while data is being received. If it isn’t blinking, it can indicate a
bad connection or that the RS-485+ and RS-485– wires are connected backwards.
The TX light will ash while data is being transmitted. For Modbus, if this light isn’t
blinking it can mean that the device isn’t being selected (wrong address) or the
communication parity or bit rate is set improperly.
In a BACnet installation, both the RX and TX lights will ash repeatedly even if no
communication is being performed. In a Modbus installation, no lights will ash if
there is no communication activity.
