controller’s rack. The card provides a convenient way to update firmware on

firmware.
• To temporarily boot the controller from firmware on the microSD card rather than from
the firmware in the controller, for example to test new firmware.
• To update, run, or test new PAC Control strategies if the controller is not on the
network, if PAC Control isn’t available, or if you want to test a new strategy without
