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-4516 is a dual temperature, dual dial thermostat for individual day and night control or weekend setback. Functionally it is similar to the T-4506; however, it features an additional output air terminal which can be used as an on-off switchline pressure. The manual indexing switch is standard on this thermostat. Depressing the
switch exhausts the switchline pressure and restores day operation of the individual thermostat without affecting other system thermostats. The switch can be unlatched manually or will automatically reset with the day cycle.
