A method of providing treatment for a medical condition includes storing a plurality of closed loop control algorithms in memory accessible by the control unit and receiving. A control unit receives analyte data from an analyte sensor in communication with the control unit. The control unit controls a medication delivery device in accordance with the first closed loop control algorithm based on the analyte data. The control unit causes the medication delivery device to be controlled in accordance with the second closed loop control algorithm instead of the first closed loop control algorithm, and controlling the medication delivery device in accordance with the second closed loop control algorithm. The control unit is configured to transmit one or more closed loop control operations to control the medication delivery device.
