Schneider Electric 2211-012 Single-Pipe Pneumatic Room Thermostat 55-85°F

The Schneider Electric (Barber Colman) 2211-012 is a single-pipe pneumatic room thermostat designed for direct-acting (DA) HVAC control applications. This reliable pneumatic controller provides precise temperature control with an adjustable setpoint range of 55°F to 85°F, making it ideal for commercial and institutional heating and cooling systems.

Key Features:

• Single-pipe pneumatic control system for simplified installation
• Direct-acting output configuration for compatibility with standard pneumatic actuators
• Adjustable temperature range: 55°F to 85°F
• Durable construction suitable for commercial building applications
• Compatible with standard 13-20 PSI pneumatic control systems
• Simple, reliable mechanical operation with no electrical connection required

This pneumatic thermostat is commonly used in older commercial HVAC systems and retrofit applications where pneumatic controls are still in service. The direct-acting design increases control pressure as temperature rises, making it suitable for cooling applications or heating systems with reverse-acting actuators.
