Johnson Controls a350ps-7 Proportional Temperature Controller

Product Description

The Johnson Controls a350ps-7 is a proportional temperature controller with an integrated sensor and adjustable set point, designed for use in HVAC and building automation applications. The unit covers a control range of 60 to 105 degrees F (16 to 41 degrees C), making it well suited for comfort cooling, ventilation, and light commercial temperature regulation. It provides proportional control output, which modulates a connected device in response to measured temperature rather than simple on/off switching. Licensed HVAC technicians and building controls specialists are the primary installers of this device.

The a350ps-7 is used in applications where proportional modulating control improves system efficiency and comfort compared to standard two-position control. Typical installations include air handling units, fan coil systems, and ventilation equipment in light commercial or residential settings. The integrated sensor reduces field wiring complexity by combining the sensing element and the controller into a single assembly. The set point range of 60 to 105 degrees F covers the majority of occupied-space comfort control scenarios.

Key Features

• Proportional control output for smooth, modulating temperature regulation
• Integrated sensor included with the controller assembly
• Set point range of 60 to 105 degrees F (16 to 41 degrees C)
• Suitable for HVAC comfort cooling and ventilation control applications
• Combined sensor and controller design simplifies field installation

Compatibility

Designed as an OEM-style proportional temperature controller for use in HVAC air handling, fan coil, and ventilation control systems requiring a 60 to 105 degrees F sensing and set point range.

Installation Notes

Installation should be performed by a licensed HVAC technician or building controls specialist familiar with low-voltage control wiring. Power down the control circuit and verify zero voltage before making any wiring connections. Follow all applicable local codes and manufacturer wiring diagrams when connecting the controller to actuators or controlled devices. Ensure the sensor element is positioned in the airstream or space in accordance with the application requirements for accurate temperature response.
