These thermostats have a single setpoint to control heating and cooling systems at one temperature for basic temperature control in older schools, hospitals, and commercial buildings. Pneumatic thermostats regulate the temperature using compressed air for power.

The 2211 Series Pneumatic Room Thermostat is designed for proportional control of pneumatic devices and actuators in environmental control systems. These one-pipe thermostats are force-balanced and utilize an external restrictor in the supply line. Their design incorporates a highly sensitive bimetal thermostatic element and a ball valve for pneumatic feedback, which ensures accuracy and stability over the entire operating range.
These thermostats have a serrated thumb wheel for setpoint adjustment.
