1. A rooftop heating, ventilation, and air conditioning (HVAC) unit comprising:
a cabinet;
an energy recovery wheel which is configured to be mounted within the cabinet, wherein the energy recovery wheel is configured to transfer heat between an outdoor air stream and a return air stream when in an operational mode and is further configured not to transfer heat between the outdoor air stream and the return air stream when in a bypass mode;
a plurality of dampers configurable to direct the outdoor air stream and the return air stream through the rooftop HVAC unit, either through the energy recovery wheel or around the energy recovery wheel, wherein the plurality of dampers includes an exhaust outlet damper which is configured to allow the return air stream out of the energy recovery wheel through an exhaust outlet when opened; and
a controller which is configured to adjust the plurality of dampers based on a selection between the operational mode and the bypass mode of the energy recovery wheel.
