George Risk Industries Inc. 2600-W Water Temp Sensor 4-wire

Product Description

The GEORGE RISK INDUSTRIES INC. 2600-W is a closed-loop water temperature sensor designed for use in hydronic and water-based HVAC systems. It operates on a 4-wire configuration, which supports more accurate signal transmission over longer wire runs compared to 2-wire sensors. The 2600-W monitors water temperature within a closed loop and feeds that data to a controller or building automation system, allowing the system to stage heating or cooling equipment based on actual fluid temperature. It is installed by licensed HVAC technicians and controls specialists working on hydronic heating, chilled water, or process water applications.

This sensor is suited for closed-loop hydronic systems in both residential and light commercial settings. Typical installation points include supply or return lines on hot water heating systems, chilled water coils, and process fluid loops where continuous temperature monitoring is required for proper system control. The 4-wire terminal connection allows straightforward integration with most standard controllers and thermostats that accept remote temperature inputs.

Key Features

• Closed-loop water temperature sensing for hydronic HVAC applications
• 4-wire terminal configuration for accurate signal over extended wire runs
• White housing finish suitable for wall or pipe-mount installation environments
• Single-unit packaging for straightforward replacement or new installation

Compatibility

Designed as an OEM-style replacement or new-installation temperature sensor for closed-loop hydronic and water-based HVAC control systems accepting 4-wire remote temperature sensor inputs.

Installation Notes

Installation should be performed by a licensed HVAC technician or controls specialist. Shut down the hydronic system and relieve any system pressure before accessing sensor mounting points on the pipe or manifold. Follow all applicable local mechanical codes and manufacturer wiring diagrams when terminating the 4-wire leads at the controller. Do not energize the control circuit until all wiring connections are secure and the system is reassembled.
