Aaon P86650 Temperature Control

The Aaon P86650 Temperature Control, also identified as the Johnson Controls A350PS-1C, is a high-performance proportional plus integral (PI) electronic control designed for precise climate management. Operating on 24Vac, this HVAC part delivers simultaneous analog outputs of 0-10Vdc and 0-20mA to modulate valves, dampers, and heating or cooling equipment. The unit supports a wide setpoint range from -30 to 130 degrees F (-35 to 55 degrees C) and features an adjustable differential of 2 to 30 degrees F, allowing technicians to fine-tune system stability. Included with the controller is the A99BC-25 silicon sensor, making it a complete solution for modulating HVAC control applications in Aaon furnaces, air handlers, and rooftop units. Its modular, NEMA 1-rated design ensures the Aaon P86650 can be easily expanded with staging or display modules for versatile system integration.

Key Benefits:

• Precision Modulation: Uses proportional plus integral control logic to eliminate setpoint offset and maintain stable environmental conditions.
• Dual Analog Outputs: Simultaneously provides 0-10Vdc and 0-20mA signals to interface with industry-standard actuators.
• Broad Temperature Range: Covering -30 to 130 degrees F, it is suitable for both refrigeration and comfort cooling/heating applications.
• Easy Installation: Compact NEMA 1 enclosure supports 35 mm DIN rail mounting and features plug-together connectors for rapid modular expansion.
• Reliable Sensing: Packaged with a high-accuracy A99BC-25 PTC silicon sensor for consistent temperature feedback.

Common Questions:

Can I use the Aaon P86650 for both heating and cooling?
Yes, the Aaon P86650 features a field-selectable jumper for direct or reverse acting modes, making it compatible with both heating and cooling equipment.

What is the purpose of the adjustable throttling range?
The adjustable differential (2 to 30°F) allows you to set the proportional band, ensuring the system responds appropriately to load changes without excessive cycling.

How do I power this temperature controller?
The unit requires a 24Vac Class 2 power supply. Always observe correct polarity during HVAC controller wiring to prevent damage to the electronics.
