Bard 8406-112BX - Low Ambient Pressure Control
The Bard 8406-112BX Low Ambient Control (350/225) is an OEM pressure control used on select Bard wall mount and packaged HVAC systems to help maintain stable cooling operation when outdoor temperatures drop and head pressure can fall off. This control cycles the condenser fan based on refrigerant pressure, using a cut-in around 350 psi and a cut-out around 225 psi, which helps support proper condenser performance and more consistent system operation in cooler weather. If your unit short cycles on low pressure, struggles to cool during cold weather operation, or you are restoring a factory low ambient setup, 8406-112BX is the correct Bard-made replacement to match original electrical fit and operating characteristics. Always confirm compatibility by model and serial number before ordering.

What does the "BX" suffix mean?
Bard uses suffixes like "BX" to manage parts internally. These do not change the physical form or function of the part.
A part number ending in "BX" simply means it is packaged in a box for shipping, rather than for internal assembly use.
Example: 8406-142BX is physically identical to 8406-142.
