This SPST (single-pole, single-throw) control is configured to open on a rise in temperature, making it suitable for high-limit or over-temperature protection applications. It features a 10-foot capillary tube connected to a sensing bulb measuring 0.290 inches in diameter by 2.52 inches in length. The adjustable differential, ranging from 6 to 24 degrees F, allows technicians to fine-tune the operating band to match system requirements. Licensed HVAC and refrigeration technicians are the primary installers of this control.\u003c\/p\u003e\n\u003cp\u003eThe A19ABB-2C is applied in residential and light commercial HVAC, refrigeration, and process temperature control systems where the sensing element must be located remotely from the switching mechanism. With a setpoint range of 50 to 200 degrees F, this control covers a broad range of heating and cooling applications including duct-mounted sensing, equipment protection, and process temperature switching. It is well suited for any installation requiring accurate remote-bulb temperature switching with field-adjustable differential settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSPST open-on-rise action provides reliable high-temperature limit or over-temperature cutout switching\u003c\/li\u003e\n  \u003cli\u003e10-foot capillary tube allows the sensing bulb to be positioned remotely from the control body\u003c\/li\u003e\n  \u003cli\u003eSensing bulb dimensions of 0.290 inches diameter by 2.52 inches length for precise thermal response\u003c\/li\u003e\n  \u003cli\u003eSetpoint range of 50 to 200 degrees F covers a wide variety of heating and cooling applications\u003c\/li\u003e\n  \u003cli\u003eField-adjustable differential of 6 to 24 degrees F for customizable system response\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation remote bulb temperature control for residential and light commercial HVAC and refrigeration systems requiring SPST switching with a 10-foot capillary remote sensing bulb.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC or refrigeration technician. Disconnect and lock out all electrical power to the equipment before removing the existing control or mounting the A19ABB-2C. Route the capillary tube carefully to avoid kinks, sharp bends, or contact with moving parts that could damage it. Wiring must comply with applicable local codes and the National Electrical Code (NEC).\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eControl Output\u003c\/strong\u003e: SPST\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAction\u003c\/strong\u003e: Open on Rise (Open High)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSetpoint Range\u003c\/strong\u003e: 50 to 200 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDifferential\u003c\/strong\u003e: 6 to 24 degrees F (adjustable)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCapillary Length\u003c\/strong\u003e: 10 feet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBulb Diameter\u003c\/strong\u003e: 0.290 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBulb Length\u003c\/strong\u003e: 2.52 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSensor Type\u003c\/strong\u003e: Remote Bulb\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: JOHNSON CONTROLS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: A19ABB-2C\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"JOHNSON CONTROLS","offers":[{"title":"Default Title","offer_id":51283999293746,"sku":"A19ABB-2C","price":242.67,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309279036.jpg?v=1781065572","url":"https:\/\/voomisupply.com\/products\/johnson-controls-a19abb-2c-remote-bulb-temperature-control","provider":"Voomi Supply","version":"1.0","type":"link"}
