Bard HVAC 8406-112BX Control
The Bard 8406-112BX Low Ambient Control is a critical high-pressure switch designed for performance stability in specialized HVAC applications, particularly in wall-mount units and telecommunications shelters. This encapsulated pressure switch operates with a fixed 350 PSI cut-out and a 225 PSI cut-in, ensuring precise head pressure regulation during low-load or cold-weather operations. By cycling the condenser fan motor, the 8406-112BX prevents evaporator freeze-ups and maintains the thermal expansion valve's pressure drop, protecting the compressor from liquid slugging. Built for durability in extreme environments, this SPST pressure control features heavy-duty leads and a hermetically sealed housing to prevent moisture intrusion and vibration-induced failure. For contractors managing Bard wall-mount heat pumps or air conditioners, this HVAC low ambient kit component provides the reliable setpoints required to maintain system equilibrium when outdoor temperatures drop below standard operating thresholds.
Key Benefits for Technicians- Optimized Head Pressure: Maintains consistent 350/225 PSI setpoints to ensure proper refrigerant flow in cooling mode during low ambient conditions.
- System Protection: Reduces the risk of compressor damage by preventing low suction pressures and evaporator icing.
- Field Reliability: High-cycle life construction designed specifically for the demanding duty cycles of commercial Bard HVAC systems.
- Direct Fit: Engineered for seamless integration into existing Bard control circuits, minimizing labor hours during replacement or upgrades.
- Environmental Resilience: Encapsulated design protects internal contacts from debris, oxidation, and humidity.
What happens if the low ambient control fails?
A failed control can result in the condenser fan running continuously or not at all. If it fails open, the fan will not engage, leading to high-pressure trips; if it fails closed, the evaporator may freeze during low outdoor temperatures.
Is the Bard 8406-112BX adjustable?
No, this is a fixed-setting encapsulated switch. The 350 PSI cut-out and 225 PSI cut-in setpoints are factory-calibrated for specific system logic and should not be tampered with.
Can this switch be used with R-410A systems?
Yes, the 350 PSI and 225 PSI ratings are compatible with the pressure curves found in many R-410A low ambient cooling configurations; however, always verify the specific submittal sheet for your Bard model number.
