The Bard 8403-038BX humidistat is an OEM, non electronic humidity controller designed to provide dependable on off humidity control in Bard wall mount HVAC applications, including dehumidification control sequences where a simple mechanical setpoint is required. This boxed control adjusts across a 20 to 80 percent relative humidity range and uses SPDT switching for flexible integration with Bard control circuits, helping the system respond when space humidity rises above the selected setpoint. For best results, confirm compatibility by matching the part number to your unit’s wiring diagram or service literature before ordering, since humidity control options and required terminals can vary by model and control package.
