TS300 SERIES SENSORS
iWorX® TS300 Series Sensors are a family of wall-mounted digital temperature and humidity sensors for use with
iWorX® HVAC Controllers. These sensors feature a Sensor Link (S-Link) communication protocol which provides a
simple two-wire interface for power and exchange of sensor and control information. Control information includes occu-
pancy override selection, heat/cool status, temperature setpoints, and fan mode.
Overview
Available in six models, these iWorX® TS300 Series Sensors provide integral analog to digital conversion for elimina-
tion of noise effects and wire resistance offset between sensor and controller.
Using the digital wall sensor, the operator can monitor performance and edit operational settings.
iWorX® TS300 Series Sensors are suitable for direct-wall, 2 x 4 electrical box, 1/4 DIN electrical box, or surface box
mounting.
The TS300 series sensor measures room conditions and transmits the information to the controller via the S-Link. A
single sensor is connected directly to an application-specific iWorX® Series controller via low-cost, unshielded, twisted
pair cable. The connection between the sensor and controller is not polarity-sensitive.
Features
• Contemporary, low-profile packaging.
• Digital zone temperature indication (selectable for 0.1 or 1 degree display resolution of °F or °C).
• Self-compensating temperature conversions remove the need to calibrate over time.
• Digital zone humidity indication (selectable for 0.1 or 1% RH display resolution).
• Long-life humidity sensing element with excellent resistance to contamination and condensation.
• Pushbutton override capabilities allow occupants to switch to timed occupied mode for after hours operation.
• Displays selected system values such as setpoints, and operating mode.
• Directly connects to selected iWorX® controllers via low-cost, unshielded, twisted-pair cable, which provides both
power and communication.
• Separate wiring subbase and electronics.
