Johnson Controls A19PRC-1 Temperature Control

The Johnson Controls A19PRC-1 is a heavy-duty mechanical temperature control engineered specifically for high-moisture agricultural and demanding industrial environments. This single-stage temperature control features a SPDT switch action, making it suitable for both heating and cooling applications across a wide voltage range of 24 to 277 VAC. Designed as a direct cross for TF115-001, it utilizes a 1-3/8" x 2-1/4" coiled sensing bulb to ensure high sensitivity and accurate thermal response. The unit is housed in a rugged NEMA 4X enclosure, providing superior protection against corrosion, dust, and water ingress. With a 30 to 110 degree F setpoint range and a 3 to 12 degree F adjustable differential, technicians can fine-tune equipment cycling to prevent short-cycling and optimize system performance. The automatic reset functionality and external knob range adjuster allow for seamless onsite calibration without exposing internal electrical components.

• Corrosion Resistance: The NEMA 4X enclosure is ideal for livestock barns, greenhouses, and wash-down areas where standard controls fail.
• Versatile Compatibility: Broad electrical ratings allow this A19 series control to manage fans, compressors, or heaters on various circuit voltages.
• Precise Tuning: The adjustable differential ensures tight temperature regulation, improving energy efficiency in industrial HVACR systems.
• Ease of Service: Simple mechanical temperature control design eliminates the complexity of electronic boards, providing long-term reliability in harsh conditions.

Is the A19PRC-1 suitable for outdoor installation?
Yes, the NEMA 4X enclosure is designed for high-protection environments, including those requiring wash-down capabilities or exposure to corrosive elements.

Can this control replace a TF115-001?
The A19PRC-1 is an exact technical cross-reference for the TF115-001, maintaining the same form, fit, and 30-110°F range.

What is the benefit of the coiled bulb design?
The coiled sensing bulb increases surface area contact with the air, resulting in a faster response time compared to standard straight remote bulbs.
