Schneider 2212-618 DA Pneumatic Stat Kit 2-Pipe, White

Designed for proportional control of pneumatic devices and actuators in environmental control systems. These two-pipe thermostats incorporate a highly sensitive bimetal thermostatic element and a pilot operated relay with pneumatic feedback for accuracy and stability over the entire operating range. These thermostats have a serrated thumb wheel for setpoint adjustment. Models are also available with preassembled internal dial stops. Thermostat covers are available in various styles to meet particular requirements. Cover options include models with a setpoint scale and a thermometer, a setpoint scale only, a thermometer only, or blank. An external setpoint adjustment cover is available on some models, or can be field-installed on covers where desired.
