Reverse Acting Non-Relay Vertical Pneumatic Thermostat

The T-4000 Series Pneumatic Room Thermostats provide individual space temperature control in all types of heating and cooling applications. By producing a proportional output signal, these thermostats modulate controlled devices in response to load changes in the space. This imposes the least demand on mechanical heating and cooling apparatus. A variety of high volume output and low volume output controllers are available to meet the functional requirements of any control system. Auxiliary devices are available to perform functions such as two-position action, high-low pressure selection, sequencing, etc. FeaturesAdjustable Sensitivities and Set Points Individual Set Points on Dual Temperature ControllersPneumatic Feedback for Greater AccuracyVibration and Shock ResistantMeets Governmental and Commercial RequirementsSingle or Dual Bimetal Sensing ElementsElement Identification LabelsRugged Construction and Decorative Design The T-4100 is a single temperature thermostat. The unit features exposed or concealed set point adjustment and a standard Fahrenheit and Celsius thermometer. With the use of a remote restrictor, this instrument requires only one air connection.
