T-3100, T-3200, and T-3300 Series Controllers

The T-3100 and T-3300 Series proportional action 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

dual temperature, dual pressure applications.
