If it's a two-pipe change over system, then there is only one coil in the FCU. In the summer, it gets supplied with chilled water from the central plant, in winter it gets supplied with hot water from the central plant.
If this is your setup, then you need a summer/winter change over switch so that the FCU controller knows whether to open the valve as temperature rises (summer) or close the valve as temperature rises (winter).
