Johnson Controls A19ABC-97C Remote Bulb Temperature Control

Product Description

The JOHNSON CONTROLS A19ABC-97C is a remote bulb temperature control designed to sense and regulate temperature in mechanical and HVAC systems. The remote bulb configuration allows the sensing element to be positioned away from the control body, enabling accurate temperature monitoring at the point that matters most. Licensed HVAC technicians and refrigeration mechanics are the typical installers for this type of control, which is used in commercial and light-commercial temperature regulation applications. The A19ABC-97C provides reliable switching action based on sensed temperature changes, making it a dependable component in refrigeration cases, chillers, unit coolers, and similar equipment.

This remote bulb temperature control is suited for applications where the sensing location is separate from the control mounting location. Typical use cases include commercial refrigeration systems, chilled water equipment, unit coolers, and HVAC air handling systems that require temperature-based switching or staging. The remote bulb design is a standard configuration in both new construction and replacement service work across light-commercial and commercial mechanical systems.

Key Features

• Remote bulb sensing element allows temperature monitoring at a location separate from the control body
• Temperature-based switching action for reliable system staging and control
• Compact control body suited for panel or equipment mounting
• Designed for use in commercial refrigeration and HVAC temperature regulation systems

Compatibility

Designed as an OEM-style replacement remote bulb temperature control for commercial refrigeration and HVAC equipment requiring remote sensing temperature switching.

Installation Notes

Installation should be performed by a licensed HVAC or refrigeration technician. De-energize all electrical circuits and shut down the system before removing or installing the control. Secure the remote bulb at the intended sensing location according to the equipment manufacturer's guidelines, and avoid kinking or sharply bending the bulb capillary. Verify all wiring connections comply with NEC requirements and applicable local codes before returning the system to service.
