Honeywell TR21-WK Wireless Temperature Sensor & Receiver Kit TR21

The Honeywell TR21-WK Wireless Temperature Sensor and Receiver Kit is specifically for use with HVAC systems. The part is a wireless temperature sensor that does not require a wire, making it easy to install in existing buildings or in areas that may be difficult to wire. The sensor sends temperature information over the air to the receiver that in turn interfaces with HVAC equipment such as furnaces, boilers, and air conditioning equipment for comfort control. Some of the advantages of this wireless setup include; ease of positioning the sensors, less time required in installation, better control of the heating and cooling zones, increased energy efficiency, and user satisfaction.
