Wireless TEC Room Temperature
Sensor System
Description
The Wireless TEC Room Temperature Sensor
System allows the wiring between the Room
Temperature Sensor (RTS) and Terminal Equipment
Controller (TEC) to be replaced with a Radio
Frequency (RF) link while maintaining the same
functionality as our standard TEC Room Temperature
Sensors.
By eliminating the wiring, labor costs can be
significantly reduced and sensor relocation
accomplished easily. Because the RF link utilizes
frequency hopping spread spectrum technology, it is
virtually immune to interference and unlikely to
interfere with other devices. Though maximum
transmission distances depend on building
characteristics, the RF link should obtain a minimum
transmission distance of 100 feet in most buildings.
The system allows signal strength to be monitored to
determine system performance in a specific building
and to optimize performance during installation.
Two devices - A wireless RTS and a TEC Transceiver
(TTX) are required to replace the wiring. The wireless
RTS is powered off of a standard lithium battery that
can be easily replaced and will operate a minimum of
five years, in most applications, before requiring
replacement.
The TTX is mounted near the TEC and is line
powered. The TTX has an antenna that can be
brought to a knockout in the event the TEC is
mounted inside an enclosure. Both the RTS and TTX
are given unique addresses that permanently bind
them to each other and allowing them to be installed
within close proximity of other wireless systems.
