Ashrae Range Hood Running Continuously.

If you have an Ashrae range hood and are finding that the hood runs all the time, Ashrae is required in some states (i.e. California) for air exchange and will run constantly at what ever CFM the unit is set to.  If the you wish not to have it run constantly you will need to turn off the Ashrae 62.2 option.  Image below shows the toggle switch from on to off.
