Why Use Wireless Room Temperature Sensor Communications?

Wireless communications between a room temperature sensor and TEC is a cost effective, reliable, and
flexible alternative to a hard-wired solution that differentiates our solutions from our competitors. For
example, in applications where wire must be run through conduit, electrician labor is expensive, and
architecture or building materials make running a cable difficult, a Wireless Room Sensor Solution is an
attractive alternative.
• Less cabling is required for room temperature sensor device installation. Low-impact installation
enables cost effective replacement of pneumatic and competitor equipment.
• Easier installation and re-configuring spares facilities the difficulties associated with rewiring to
support new cable routing.
• Factory installation of wireless transceivers by terminal box manufacturers further reduces
electrician involvement at installation time and reduces installation costs.

Hardware Components

The Wireless Room Sensor Solution is a wireless connection between P1 or BACnet TECs and room
temperature sensors that communicate via a radio frequency (RF) link instead of a hard-wired link. For
the Wireless Room Sensor Solution, a Wireless Room Sensor (WRS) communicates via point-to-point
wireless link to a Room Sensor Transceiver (RSX) device connected to a TEC device.
