The following figure is an example of a Metasys network using the TEC Series Wireless Thermostat Controller system.

Figure 1. Metasys Network with TEC Series Wireless Thermostat Controller System (BACnet IP and BACnet MS/TP Versions Shown)

Note: A system can use either a TEC20-3C-2 Coordinator (BACnet IP) or a TEC20-6C-2 coordinator (BACnet MS/TP), but cannot use both BACnet IP and BACnet MS/TP versions.

ZigBee Wireless Network (802.15.4)

Bidirectional (2.4 GHz Channelized, 2.4 GHz DSSS Wireless Protocol)

The TEC Wireless Thermostat Controller System provides a wireless interface between a network engine and the TEC Wireless Thermostat Controllers, allowing the exchange of BACnet IP (TEC20-3C) or BACnet MS/TP (TEC20-6C) messages for the purpose of wireless monitoring and temperature control of building HVAC equipment.

The system consists of at least one TEC20-3C-2 Coordinator and multiple TEC Wireless Thermostat Controllers. The system uses DSSS wireless technology and operates on the 2.4 GHz ISM band. The system meets the IEEE 802.15.4 standard for low power, low duty-cycle wireless transmitting systems and are compatible with wireless mesh networks compliant with the ZigBee standard. The TEC Thermostat Controllers use a transmission power of 10 dBm.

For general information on the TEC Series Wireless system, refer to the TEC Series Wireless Thermostat Controller System Technical Bulletin (LIT-12011414).

1 When using BACnet protocol with TEC20-3C-2s, you must specify UDP Port 47808 as being used. For multiple BACnet networks, use a different port number for each network.
2 In Unidirectional communication, only the originating device initiates requests (assuming synchronous response is allowed in the request).
