Bard HVAC 8612-023B Temp Sensor

The Bard 8612-023B Remote Temperature Sensor is a critical OEM replacement designed for high-precision thermal monitoring in commercial and industrial HVAC applications. This outdoor temperature sensor features 35-foot leads, providing the necessary length for flexible field placement when the primary controller is located away from the optimal sensing zone. As the direct engineering update for the discontinued 8612-023A, this thermistor-based component ensures seamless integration with Bard MC control series lead-lag controllers, including the MC4002 family. By delivering accurate real-time data, it allows for efficient staging and balanced operation of multiple wall-mount air conditioning units. For technicians managing telecom shelters or modular offices, utilizing a genuine Bard HVAC sensor is vital for maintaining tight setpoint tolerances and preventing unnecessary equipment cycling. Proper installation following official wiring diagrams is required to ensure correct polarity and signal integrity across the 35-foot span.

• Direct OEM Compatibility: Specifically engineered for Bard MC4002 and MC series controllers, ensuring no communication errors between the sensor and the logic board.
• Extended Lead Length: The 35 ft leads eliminate the need for field-splicing in most standard installations, reducing resistance variables and potential failure points.
• Enhanced Recovery Logic: Provides the precise feedback necessary for controllers to manage lead-lag staging, optimizing the service life of connected compressors.
• Updated Specifications: Replaces the older 8612-023A model with improved environmental sealing for reliable performance in various outdoor conditions.
• Standardized HTS Code: Classified under HTS 8415.90.8085 for straightforward parts identification and procurement.

Is the 8612-023B compatible with older 8612-023A installations?
Yes, the 8612-023B is the official updated version of the 8612-023A. It maintains the same electrical characteristics and physical footprint, making it a drop-in replacement for existing Bard systems.

Can the 35-foot leads be shortened or extended in the field?
While leads can be shortened, it is recommended to maintain the factory length to preserve calibrated resistance. If extension is required, use shielded twisted pair wire and high-quality connectors to prevent EMI interference from affecting temperature readings.

Which controllers support this remote sensor?
This sensor is primarily designed for the Bard MC Series controllers, such as the MC4000, MC4002, and MC5000 series, typically used for sequencing wall-mount HVAC units.
