TFxB Series Thermostat Controller

Getting Started
The following BACnet
®
properties are configurable and may need to be modified to effectively establish
communication on the network and to guarantee uniqueness of each device in a BACnet
®
system.
MAC Address (Default: 001)
Set between 000 and 254 via thermostat menu* (128-254 represent MS/TP non-token-passing slave devices).
Device Instance (Default: Auto)
The thermostat controller automatically configures its device instance to 153000 + MAC address. Can
also be set manually via thermostat menu* or through the WriteProperty service to Device
Object.Object_Identifier. The device’s Object_Identifier is a combination of the Device Object_Type (8)
and the Device_Instance (0-4194302), therefore its decimal or hexadecimal representation tends to be
incomprehensible. For example, the Device_Instance=1000 has an equivalent Object_Identifier of
0x020003E8 hexadecimal or 33555432 decimal. While it’s the device’s Object_Identifier property that
can be changed using a BACnet
®
WriteProperty service, this document refers mostly to
Device_Instance.
Baud Rate (Default: 0 = Auto)
The thermostat controller automatically configures its baud rate by detecting the network speed upon
connection. Can also be set manually via thermostat menu* or through the WriteProperty service to
Device Object.proprietary property #1001. This value is Unsigned type, and available values are 9600,
19200, 38400, 76800.
Max_Master (Default: 127)
To increase network efficiency or if there are less than 127 devices on the network, the Max_Master
value can be configured through WriteProperty service to the Device Object.Max_Master. For more
information, refer to the MAC address and Max_Master section on page 4.
Device Object.Object_Name
Name of device, for example TFCB24XYZ3. This value can be configured through WriteProperty
service to the Device Object.Object_Name.
* NOTE: When referring to the thermostat menu in this section, it includes the Quick Access Menu when in
operation mode (RUN) and the Installer Menu when in programming mode (PGM).Refer to the thermostat
controller’s Specification & Installation Manual for more details.
Quick Setup
Take advantage of the thermostat controller’s Auto Baud Rate Detection, Auto Device Instance Configuration,
and default Max_Master value, to get up and running with no programming.
1) Connect the thermostat controller to the network and then power up the unit. The thermostat controller
automatically configures the baud rate and device instance.
2) If you need to set a unique MAC address (default 001), continue to step 3. If not, setup is complete.
3) With the thermostat controller in Operation Mode (jumper = RUN), go to the Quick Access Menu by
pressing and holding both function buttons on the thermostat for 5 seconds. Refer to the Specification &
Installation Manual for more details.
4) Enter the password (637).
5) Set a unique MAC address.
6) Power down and then power up the thermostat controller.
Manual Setup
If your site has more than one TFxB network and/or you wish to use a Device_Instance other than 153,000,
follow these instructions.
1) With the thermostat controller in Operation Mode (jumper = RUN), go to the Quick Access Menu by
pressing and holding both function buttons on the thermostat for 5 seconds. Refer to the Specification &
Installation Manual for more details.
