SENSORS AND SEQUENCES

AboveAir Technologies offers equipment with a variety of control sequences based on the application and engineering requirements, as well as units provided for controls by others or with simple thermostat control.

The wiring diagram shipped with your unit and the submittal will indicate the control installed on your equipment. The tables below provide basic information on the application, sensors, and a link to the full sequence of operation and sensor schematic. For controls by others, contact your controls provider for control details.
