Description
The Johnson Controls T-4002-301 is a direct acting pneumatic thermostat conversion kit engineered for commercial and industrial HVAC applications where reliable pneumatic control is essential. Featuring a 55–85°F dial range, this kit allows technicians to efficiently convert or restore pneumatic thermostat systems without full equipment replacement, saving time and reducing overall project costs.
The included white cover provides a clean, professional finish that blends seamlessly into commercial building interiors. As a direct acting device, the thermostat increases branch line pressure as space temperature rises, making it well-suited for cooling applications or systems configured for direct acting control sequences.
