Lochinvar & A.O. Smith 100170643 Board
The Lochinvar & A.O. Smith 100170643 Thermostat Control Board is a critical OEM replacement part engineered for high-efficiency CB 045-260 hydronic boilers. As a dual-stage integrated boiler control, this module manages complex heating cycles by monitoring real-time system activity and adjusting firing rates to meet precise demand. It features a broad max setpoint range of 150°F to 200°F and a reliable min setpoint range of 110°F to 140°F, ensuring stable thermal performance across diverse commercial and residential applications. By replacing legacy part numbers TST30017 and TST20036, this updated KTSTAT CB 045-260 board facilitates seamless communication between the tank aquastat and outdoor sensors, optimizing gas consumption and reducing component wear. For technicians, the plug-and-play architecture minimizes field calibration time, while the high-fire offset range (0°F-20°F) allows for granular tuning of the HVAC combustion cycle to maintain peak equipment efficiency.
Key Benefits for Technicians- Precise Modulation: Advanced circuitry supports two-stage thermostat operations for enhanced temperature stability and energy conservation.
- Universal Compatibility: Direct factory replacement for various Lochinvar Knight and A.O. Smith boiler models within the 045-260 series.
- System Protection: Real-time monitoring prevents short-cycling and protects the heat exchanger from thermal stress.
- Comprehensive Kit: Typically includes the TST20036 control and INS70115 instruction set for rapid field installation.
- How do I verify if this board is compatible with my specific unit? Cross-reference your boiler's model and serial number; this board is specifically tailored for CB 045-260 series units and replaces older TST30017 modules.
- What does a 'Fault' light indicate on this module? The board monitors faults related to the outdoor sensor, tank aquastat, and internal circuit health to streamline the diagnostics process.
- Is calibration required after installing the 100170643? While primarily plug-and-play, technicians should verify the high-fire offset and setpoint ranges to match the original system design parameters.
