Wireless TECs w/Coordinator
Wireless TECs w/Coordinator
FX40
Wireless Coordinator
Zigbee Ready Communication Module
2.4 Ghz based on 802.15.4 mesh
All TEC models to be wireless capable
Approx. 30 TEC’s / Coordinator, 100 per NAE trunk
Auto Configuring Database
Simple, software set-up utility
Elementary tech training required
Scalable – multiple Coordinators / System
JCI open protocol – BACnet IP and MS/TP
Application ScopeWireless TECs w/Coordinator
• Targeted at retrofit applications where installing a communication trunk is cost prohibitive or disruption to the current business or infrastructure is sensitive.
• New construction where installing communication trunk in a region requires higher cost code / labor compliance.
• Early adopter in wireless technology

Wireless
– Focus of wireless development on replacing the network wiring.
– This allows for centralization of stand-alone equipment.
– No need to run Extra-Wiring for communication which in turn lowers installation costs.
– Benefits well suited to retrofit projects on existing equipment.
– Wired Network interface replaced with Wireless 802.15.4 (ZigBee) radio.
– Network image from wired world duplicated.
The Wireless Coordinator & Thermostats– Wireless Coordinator developed to
provide a simple way in which to integrate wireless thermostats into today’s “open-systems”
– Coordinator provides wireless network access point.
– Also serves as thermostat / network configuration tool.
– Converts 802.15.4 – JCI wireless thermostat messages to familiar BACnet objects
– Supports 30 JCI Thermostats per coordinator.
– Connects easily to BACnet IP or MS/TP network for integration.

Wireless Coordinator
– Existing Wiring from Equipment (Y-W-G) re-used.
– TEC wireless network thermostat transmits data wirelessly to gateway:
– Occupancy.
– Room set points
– equipment status

Application ScopeWireless TECs w/Coordinator
Typical Retrofit Application– Hotel project with existing multispeed
fan coil units.
– Fan coils controlled by existing electronic thermostats.
– Existing controls do not support centralization.
– Thermostats replaced with VT7000 series wireless thermostat.
– After some brief address settings and gateway configuration the wireless mesh is functional.
– Information ready for integration.
Tec Wireless Coordinator Installed on each floor.
Coordinator(s) connected with Category 5 riser.
Integration accomplished over IP network at supervisory controller.
