Bard 8612-027BX - 230V Head Pressure Control

The Bard 8612-027BX is a 230V head pressure control used as part of Bard modulating low ambient control applications on select wall-mount air conditioners, helping the system maintain stable condenser operation when outdoor temperatures drop by modulating condenser fan performance based on monitored high-side pressure. This OEM Bard control is designed to integrate with the unit’s low ambient circuitry so the refrigeration system can stay within proper operating limits during cool-weather cooling, reducing nuisance trips and supporting consistent capacity when the job requires low ambient operation. Verify compatibility by matching the exact part number and the unit’s model and serial information, and follow the applicable Bard installation instructions for proper wiring and sensor placement.

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.
