Johnson Controls A350PT-1C Proportional Temperature Controller – HVAC Regulation

Johnson Controls A350PT-1C Proportional Temperature Controller – HVAC Regulation

Condition: Used. External sensor not included

The Johnson Controls A350PT-1C is a high-performance proportional temperature controller designed for regulating temperature in HVAC systems. This unit works by adjusting heating or cooling outputs based on the deviation from the setpoint, ensuring precise and stable environmental control. It does not have an integrated sensor and requires a compatible external sensor for temperature input. Its proportional control mechanism allows for gradual and smooth adjustments, reducing system wear and enhancing energy efficiency. The A350PT-1C is ideal for use in commercial and industrial HVAC systems where tight temperature control is critical.
