Description
The Johnson Controls T-4002-9008 is a direct-acting pneumatic thermostat engineered for precise temperature control in commercial HVAC and building automation applications. Designed for horizontal mounting, this thermostat delivers dependable pneumatic signal output proportional to space temperature, making it an ideal choice for VAV systems, fan-coil units, and other pneumatically controlled HVAC equipment.
Key Features
- Direct-acting pneumatic control — output pressure increases as temperature rises
- Temperature sensing range: 12 to 30 degrees Celsius (approximately 54°F to 86°F)
- Horizontal mount configuration for straightforward wall installation
- Designed for use in commercial building automation and HVAC pneumatic control systems
- Reliable Johnson Controls engineering for long-term performance in demanding environments
Application
The T-4002-9008 is well-suited for commercial and institutional buildings where pneumatic control systems are in place. Its direct-acting operation ensures that as the space temperature increases, the branch line pressure to the controlled device also increases — enabling accurate modulation of heating and cooling equipment.
