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.

The T-4506 is a dual temperature, dual dial thermostat designed to provide individual day and night or two set point temperature control. The set point change is accomplished with a change in supply pressure. A 15 PSIG 105 kPa) supply represents the lower element and a 20 PSIG (140 kPa) supply represents the upper element. The action of both elements is the same. A change in either set point does not affect the other set point. On day-night applications with 20 PSIG representing the night set point, an optional manual indexing switch is available to restore the day temperature of the individual thermostat without affecting the other system thermostats. The indexing switch can be unlatched manually or will automatically reset with the day cycle.
