    """Fan Coil Unit (FCU) heating/cooling system (with no ventilation).

    Each room/zone receives its own Fan Coil Unit (FCU), which meets the heating
    and cooling loads of the space. The cooling coil in the FCU is always chilled
    water cooling coil, which is connected to a chilled water loop operating
    at 6.7C (44F). The heating coil is a hot water coil except when when electric
    baseboards or gas heaters are specified. Hot water temperature is 82C (180F) for
    boiler/district heating and 49C (120F) when ASHP is used.

    Args:
        identifier: Text string for system identifier. Must be < 100 characters
            and not contain any EnergyPlus special characters. This will be used to
            identify the object across a model and in the exported IDF.
        vintage: Text for the vintage of the template system. This will be used
            to set efficiencies for various pieces of equipment within the system.
