WIRELESS INSTALLATION & INTEGRATION REFERENCE GUIDE FOR TB7200/TB7300/TB7600 SERIES THERMOSTATS
HOW ORPHAN NODES ARE CREATED IN THE FIELD
Example: 2 small buildings are within a few feet of each other. Both have 6+ devices each (Fig. 15).
NOTE: A configuration like this, with communicating thermostats split between two buildings, is not recommended.
Premises
• Building A is started first.
• Yellow device has given its 6 addresses out to other devices in building A.
• Building B devices can only be connected through blue device due to maximum distance coverage.
Result
Because the blue device cannot have an address assigned by the yellow device which is within range, the blue device and
orange devices cannot join the ZigBee network.
GETTING ORPHAN DEVICES BACK ON THE NETWORK
1. Disconnect and bring one of the building B devices and power it up in building A until it joins the ZigBee network (confirmed
either at the device or using the status LED on the wireless communication card of the device).
2. When the device has joined the network in building A and is added to the Workbench station, bring it back into building B so
it can propagate ZigBee addresses to the other devices in building B.
Initial Network Startup at the Job Site
1. As shown in Fig. 16 below, first power up the orange devices in sequence and wait until they are joined to the network or
matched to their offline created counterparts.
2. All the remaining yellow devices / nodes / controllers can now all be powered up to also join the network.
3. This start-up sequencing allows for ALL devices to be discovered without creating orphan nodes.

Initial Network Startup at the Integrator's Office
1. Power up the WEBs-AX controller with the wireless communication card installed and set the PAN ID and Channel.
2. Power up the first thermostat or repeater to add to the Workbench. Once it has an address, which you can see in the Work-
bench under the device's property sheet, it has used one of the six addresses the controller can assign.
3. Continue adding devices to the network with one thermostat previously added always powered up so there will be sufficient
device addresses available. For example, if you have 48 thermostats to add to the station, the controller and seven other
devices would be needed to assign addresses to all of the other devices being added to the network.
