3-inch diameter unit features a dual-voltage 115/230V configuration

Dirt Handling Capability: The top-mounted valve design allows small particles to be purged without clogging the 1/8" orifice

The close on rise switch action—meaning contacts close as the temperature increases—allows for direct control of compressors or refrigerant solenoid valves without the immediate need for auxiliary relays in many line voltage configurations

Contractors favor this model for its HVAC system diagnostics compatibility and ease of field integration

the internal bimetal disc may have lost its calibration
