Honeywell TR23 Wall Module

The Honeywell TR23 Wall Module is a dedicated LonWorks networked sensor designed for seamless integration with Excel 10, 15, and other controllers utilizing a 20 K Ohm NTC non-linear sensor. This unit serves as a critical interface for building automation systems, providing precise HVAC temperature control within a 55?F to 85?F setpoint range. Built for field flexibility, it features a LonWorks bus network jack for local tool access and a manual override button with LED status indication to signal temporary occupancy or bypass modes. The hardware supports multiple configuration options, including selectable setpoint dials for Fahrenheit, Celsius, and Relative (- to +) scales. Designed for standard installations, the Honeywell TR23-KL mounts directly to 2"x4" or 60mm junction boxes, making it a reliable solution for commercial Honeywell wall module replacement projects where networked zone sensing and robust communication are required.

Key Benefits for Technicians

• Direct LonWorks Integration: Features an accessible LonJack for rapid networked HVAC sensor commissioning and troubleshooting directly at the wall unit.
• Universal Setpoint Options: Includes three field-interchangeable dials (F, C, and Relative) to match specific commercial thermostat requirements.
• Reliable Sensor Accuracy: Utilizes a 20 K Ohm NTC thermistor to ensure stable environmental data for Excel 10 controllers.
• Rugged Occupancy Control: The integrated override button allows occupants to trigger timed bypass modes without complex programming.

Common Questions

Is the TR23 compatible with non-LonWorks systems?
The TR23 is specifically engineered for systems utilizing 20 K Ohm NTC inputs and LonWorks communication; always verify your controller's input requirements before installation.

How do I access the LonWorks network through this module?
You can connect a networked sensor tool via the 3.5mm LonWorks bus network jack located on the side of the housing for local monitoring and configuration.

What mounting hardware is required for installation?
The unit is designed to fit a standard 2"x4" junction box or a 60mm diameter box, allowing for straightforward HVAC wall module retrofits in most commercial settings.
