The hot gas re-heat circuit has a re-heat coil positioned adjacent to the first evaporator and is configured, when enabled, to bypass the first condenser and to permit refrigerant to flow from the first compressor through the re-heat coil to the first evaporator. The method also includes the steps of enabling the first refrigerant circuit and the second refrigerant circuit in response to a demand for humidity control and a demand for cooling, where in the demand for cooling is one of a demand for stage one cooling and a demand for stage two cooling, and enabling the hot gas re-heat circuit in response to a demand for humidity control and a demand for stage one cooling.
