Description
The Schneider Electric (Barber Colman) 2216-126 is a direct acting, three-pipe pneumatic thermostat designed for day/night temperature scheduling in commercial HVAC applications. Built without dial limit stops for maximum setpoint flexibility, this thermostat ships with a remote sensing element, allowing it to respond to conditions at a location separate from the thermostat body — ideal for fan coil units, VAV systems, and other commercial pneumatic control applications.
Key Features
- Direct acting pneumatic operation — branch pressure increases as temperature rises
- Three-pipe configuration for reliable day/night (occupancy/unoccupied) setpoint switching
- Day/night switching capability enables energy-saving setback during unoccupied periods
- Supplied without dial limit stops for unrestricted setpoint adjustment range
- Includes remote sensing element for accurate zone temperature measurement at a remote location
- Designed as a drop-in replacement for legacy Barber Colman pneumatic thermostat applications
- Part of the Schneider Electric (Barber Colman) 2216 series pneumatic thermostat family
Application
The 2216-126 is well suited for commercial buildings utilizing pneumatic control systems, including offices, schools, hospitals, and multi-zone facilities. The three-pipe design allows the building automation system to remotely switch between day and night setpoints via a pneumatic signal, reducing energy consumption during unoccupied hours. The remote sensor configuration makes this model ideal for installations where the thermostat must be mounted away from the controlled space, such as in a corridor or mechanical room.
