Johnson Controls S350PQ-1 Proportional Temperature Staging Module with 0-30°F Offset

The Johnson Controls S350PQ-1 is a proportional plus integral temperature staging module designed to work in conjunction with the A350 series temperature controls. This add-on module expands system capabilities by providing proportional or proportional plus integral staging control for HVAC applications.

Key Features:

• Adjustable offset range from 0 to 30°F (0 to 17°C) for precise temperature staging control
• Field-selectable reverse acting (RA) or direct acting (DA) operation modes via jumper configuration
• Proportional control capability for smooth, modulated HVAC equipment operation
• Plug-together modular design with 35mm DIN rail mounting for quick installation
• Receives power and control signals directly from the A350 temperature control
• Compatible with A350P proportional temperature controls for multi-stage heating and cooling applications

The S350PQ-1 is ideal for applications requiring staged control of HVAC equipment such as air handling units, modulating damper actuators, and mixed air control systems. The adjustable offset potentiometer allows technicians to fine-tune the staging point relative to the A350 controller's setpoint, ensuring optimal system performance and energy efficiency.
