Weil McLain 383-500-602 - 383-500-602 Return/Supply Temperature Sensor

Maintain precise temperature control across your hydronic loop with the Weil-McLain 383-500-602 Return/Supply Temperature Sensor. Designed to bridge the gap between boiler output and system load, this sensor, part number 383-500-602, monitors fluid dynamics to ensure your heating equipment operates within designated parameters for optimal fuel economy.

This device functions by providing high-fidelity resistance data back to the boiler control board. By continuously tracking the temperature of circulating water on both the supply and return lines, the system can intelligently modulate firing rates to meet immediate thermal demand without causing temperature overshoot or cycling inefficiencies.

Key System Performance Baselines:

• Precision Sensing: Delivers accurate thermal feedback for exact boiler modulation.
• Rugged Build: Constructed to withstand the high-temperature fluctuations and vibration common in hydronic environments.
• Streamlined Integration: Compact form factor allows for simple, rapid installation in tight mechanical room spaces.

⚠️ Application Profile: Primarily utilized in residential and light commercial boiler systems, this sensor is specifically engineered for compatible Weil-McLain high-efficiency boilers requiring dual-point temperature monitoring to optimize hydronic heating output.
