Remove Unwanted Default Values in OpenStudio

edit

Is there a way to remove unwanted default values in the OpenStudio application? For example, when using a SetpointManager:OutdoorAirReset, if you click on the field "Setpoint at Outdoor Low Temperature 2" it goes from being blank to having a value of 0 when you click off it. Upon translation to IDF this value also gets translated. I know I can easily remove the field value in a text editor, but just wanted to check if there is anyway to do it in the application itself.
