2211 Series Room Thermostat, Proportional Thermostat, Direct Acting, One Pipe

Proportional Thermostat, Direct Acting, One Pipe, without dial limit stops. 55 to 85 °F Setpoint Range, 0.017 scfm at 20 psig (0.48 L/m at 138 kPa Air Consumption, single temperature. These pneumatic room thermostats are designed for proportional temperature control of pneumatic valves and damper actuators to maintain room air temperatures in heating, ventilating, and air conditioning systems.

Application

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.
