Lochinvar & A.O. Smith 100170645 Sensor
The Lochinvar & A.O. Smith 100170645 System Sensor kit is a critical diagnostic and control component designed for high-efficiency hydronic systems. As a genuine OEM boiler communication kit, it provides the precise thermal feedback necessary for the control module to manage firing rates and maintain target setpoints. This kit is specifically engineered for Lochinvar Knight and A.O. Smith commercial boilers, as well as AQUAS Low NOx indirect pool heaters. It includes a high-accuracy NTC thermistor sensor and a compatible bulbwell to ensure a dry, secure interface with the system piping, preventing leaks while maximizing thermal conductivity.
For service technicians, this 100170645 system sensor is the standard replacement for legacy part number TST30019. It integrates seamlessly with existing communication harnesses to eliminate "Sensor Open" or "Sensor Short" fault codes that cause system lockout. By accurately monitoring return water or system supply temperatures, this kit enables advanced modulation features, reducing short-cycling and increasing overall energy utilization efficiency in demanding commercial HVACR applications.
Key Benefits- Precision Thermal Monitoring: Provides real-time temperature data to the boiler control module for optimized modulation and firing rate accuracy.
- Complete Assembly: Includes a dedicated bulbwell and communication module components to facilitate a professional, leak-free installation.
- Direct OEM Compatibility: Engineered as a drop-in replacement for Lochinvar Knight and A.O. Smith units, ensuring electrical and physical fit.
- Enhanced Reliability: Resolves common communication errors and sensor-related lockout issues in high-demand hydronic systems.
- Rugged Build Quality: Designed to withstand the thermal stress and high-pressure environments of industrial boiler rooms.
What boiler models are compatible with this sensor kit?
This kit is primarily used in Lochinvar Knight (WH/KB) series boilers and A.O. Smith commercial equivalent models. It is also found in AQUAS indirect pool heating systems.
Can this sensor replace the TST30019 part?
Yes, the 100170645 is the direct manufacturer-authorized replacement for the older TST30019 sensor assembly.
Do I need to drain the system to install the bulbwell?
If you are replacing an existing bulbwell, the system must be isolated and drained at the header. If only the sensor probe is being replaced within an existing dry well, draining may not be necessary; however, always verify the integrity of the well first.
