T-3100, T-3200, and T-3300 Series Controllers
The T-3100 and T-3300 Series proportional action W ARM
pneumatic thermostats are designed to maintain
temperature in accordance with the return air
temperature in terminal air conditioning units. The
T-3200 Series of pneumatic thermostats are designed
to control pneumatic actuators in single temperature,
dual pressure applications.
The T-3111 and T-3311 Series controllers are
combination pneumatic thermostats and valve
actuators. The T-3111 provides proportional control of
a steam or water valve on a single temperature
application, while the T-3311 provides control in Figure 1: T-3100 Remote Mounted Thermostat and
dual temperature, dual pressure applications. T-3311 Valve Top Thermostat
