Adding field to Fan coil unit inputs

I am using v1.14 and trying to model a Fan coil unit with fan operating on a schedule- unfortunately, the osm file does done have supply air fan operating mode field that makes it relevant to operate the unit at that schedule and cycle it per demand at other hours. It is only operating as either run as constant(24X7) or cycling it on demand(OA cycles as well!!!!). How can I get this to work? The following text is from energy plus i had edited to make it work. I prefer to stay in the open studio platform inorder to run parametrics using PAT. Please help!!!!
