are on a bus.
TIPS AND THINGS YOU NEED TO KNOW
•
Each thermostat is delivered from the factory with the default MAC address set at 254. At this value, BACnet communication is
NOT active and the device will not participate in the token pass either. The local LED status for the communication adapter at
this point is one short flash only. To enable BACnet communication, set the local MAC address configuration property of the
thermostat to any valid value from 0 to 127.

After the initial configuration of your device and if your BAS allows you to remove objects, we suggest that you remove all the
configuration objects to prevent unnecessary polling of non used objects and to help speed up the network.
All configuration objects are available and accessible locally from the device itself using the local configuration routine. Please
refer to the PIR Application Guide for TB7200 and TB7300 Series Thermostats (form number 63-4526).
In its default mode of operation, the device will automatically match its baud rate to the baud rate of the network. Automatic
baud rate detection will occur when the MS/TP communication port is initialized (on power up). If the network speed is
changed, the device will keep listening at the previously detected speed for 10 minutes before resuming auto-bauding. Re-
powering the devices will force immediate auto-bauding.

Enumeration sets for System Mode MV16 depends on Sequence of Operation (MV15) value upon device discovery. If
required enumerations are not present, set MV15 to desired value and rediscover MV16 object. Available enumeration will
now reflect required configuration.
Enumeration sets for MV16 depends on Fan Mode Sequence (MV58) value upon device discovery. If required enumerations
are not present, set MV58 to desired value and rediscover MV16 object. Available enumeration will now reflect required
configuration.
Enumeration sets for MV26 and MV27 depend on Control Type (BV75) value and Pipe Number (MV52) value upon device
discovery. If required enumeration is not present, set BV75 and MV52 to desired value and rediscover MV26 and BV27 object.
Available enumeration will now reflect required configuration.
If the device should go off-line, the following binded thermostat parameters will be released:

The BACnet Data Link layer has two key parameters: the device object name and the device object ID. The device object
name must be unique from any other BACnet device object name on the BACnet network (i.e. not just the MS/TP sub-
network). The device object ID must be unique from any other BACnet device object ID on the entire BACnet network (i.e. not
just the MS/TP sub-network).
