General Maf Sequence of Operation

About this detail

The control diagram outlines the operational sequence and point mapping for the mechanical makeup air unit and supply fan. A duct-mounted temperature sensor senses supply air temperature while the equipment controller modulates the heating control valve to maintain the setpoint. System interlocks require verification of the outside air isolation damper status prior to enabling the supply fan, along with an interlock with exhaust fan EXF-42. Points include analog outputs, digital inputs, variable frequency drive control, and fire life safety interfaces.
