T-4002-9014 Johnson Controls Thermostat

Overview

The Johnson Controls T-4002-9014 is a high-volume output, single-temperature pneumatic room thermostat designed to provide proportional control of pneumatic valves and damper actuators. This reverse-acting controller is specifically engineered for vertical mounting and is a reliable solution for individual space temperature control in commercial and industrial HVAC systems. It is part of the legacy T-4000 series, known for its durability and precision in heating and cooling applications.

Features

• Reverse-acting control operation to modulate pneumatic devices
• High-volume air flow output suitable for larger pneumatic systems
• Vertical mounting orientation for standard wall installations
• Exposed adjustment dial for convenient temperature setpoint changes
• Proportional output signal responds accurately to load changes
• Adjustable sensitivity to fine-tune system performance
• Two-pipe configuration for streamlined air transmission
