Honeywell Room Temperature Sensor - TR21/U

Honeywell presents the highly efficient Room Temperature Sensor, engineered with a 20K ohm NTC non-linear thermistor sensing type. Housed within a sturdy, white plastic enclosure, it promises long-lasting performance.

Certain models provide a setpoint adjustment feature for accuracy and preference considerations. The occupied/unoccupied override function is available on specific models, accompanied by an LED indication. Additionally, models equipped with either a 3-position (Auto/0/1) or a 5-position (Auto/0/1/2/3 Speed) fan switch cater to a range of cooling requirements.

However, note that the TR21 and TR21-A models exclude the LonWorks Bus Jack, included in all other models for enhanced versatility. A user-friendly operating range from 45 F to 99 F (7 C to 37 C) makes it compatible for various environments.

Models TR22 and TR23 come equipped with user-selectable temperature setpoint dials in Fahrenheit, Celsius, and relative (- to +) modes. Technically structured configuration for room-specific adjustments, primarily wall mountable with the sensor application focusing on temperature. All these excellent features outline this Room Temperature Sensor as a premium choice in industrial automation and control systems.
