The MyStat Startup UI guides the user through the initial device setup and operational mode selection during device power ON or reboot. During startup, the user can select one of three operational modes: Pair with CCU, Standalone, or Test Mode. Based on the selected mode, the device either performs CCU pairing, configures standalone operation, or enters output testing mode for validation purposes. After successful configuration in both Pair with CCU and Standalone modes, the device automatically restarts and transitions to the Home screen for normal runtime operation.
