TROB24 Series Thermostat
Page | 3
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 to between 000 and 254 via thermostat menu* (128-254 represent MS/TP non-token-passing slave
devices).
Device Instance
(Default: Auto)
The thermostat automatically configures its device instance to 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 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 TROB24T4XYZ1. 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’s
Specification & Installation Manual for more details.
Quick Setup
Take advantage of the 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 to the network and then power up the thermostat. The thermostat 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 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 thermostat’s
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
Manual Setup
If your site has more than one TROB24 network and/or you wish to use a Device_Instance other than 153,000,
follow these instructions.
1) With the thermostat 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 thermostat’s
Specification &
Installation Manual
for more details.
