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. 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.
