FIRMWARE 4.1 Lighting Modes 4.1.1 White Light The unit is illuminated by white LED array. 4.1.2 CCT This unit offers a range of CCT levels with infinite adjustability via the smartphone app and wall control. Voice control can change CCT between 4 preset values (3000K, 3500K, 4000K, and 5000K). 4.1.3 Off No LEDs are illuminated. 4.2 Dimming The unit shall be capable of dimming in any lighting mode. 4.2.1 Levels There shall be ten distinct selectable dimming levels between 10% and 100% light output. Dimming levels shall provide a linear change in the perceived light output. This is to be achieved using a logarithmic control profile. 4.2.2 Variables The dimming levels at any CCT setting shall be independent variables, not carrying over between temperatures i.e. adjusting the dimming level in 5000K mode will not affect the dimming level in the other modes, and vice versa. 4.2.3 Retention The dimming level and CCT variables shall be stored and retained, such that when the unit is changed to the Off mode, then back to an illuminated mode, it illuminates at the previously used dimming and CCT level. 4.2.4 Upgrades Firmware shall be upgraded via cloud OTA (minimum) or wireless connection between app and fan. Hardware and firmware shall be designed to ensure that a failed firmware update will not result in a bricked device. 4.3 Button Actions 4.3.1 Press For a momentary RF transmission from 25 to 1200 ms, the corresponding action shall be executed at the end of the transmission (release of the button). See Figure 9. Figure 9: Button Press Action 4.3.2 Press & Hold For a transmission lasting longer than 1200 ms, the corresponding action shall be executed immediately. Press &

hold actions that are adjusting a multi-level variable, such as increasing or decreasing dimming levels, shall be executed continuously until either the transmission is ended or the end of the adjustment range is reached, whichever comes first. See Figure 10. Figure 10: Button Press & Hold Action 4.4 Responses to Button Actions 4.4.1 Transitions Transitions between variable levels (dimming levels, CCT levels) shall be smooth, and not an abrupt step. Note the ramped change in variable level depicted in Figure 9. 4.4.2 Responses to Inputs Table 1: Button Responses 4.5 Control Pairing 4.5.1 Pairing Window The system shall accept new control pairings, including overwriting an existing control pairing, only during the first 3 minutes after powering the system. This window must be capable of being initiated both by switching the master power source to the driver, as well as by disconnecting and reconnecting the control module from an already powered driver. 4.5.2 Pairing Pairing of the wall control to the communication module shall be achieved by executing a special press & hold action, as defined in Table 1. 4.5.3 Un-pairing Un-pairing of the wall control to the communication module shall be achieved by executing a special press & hold action, as defined in Table 1. 5. REGULATORY & CERTIFICATION COMPLIANCE The system and all components shall comply with the following regulations.
