 - `Dimmer Automatic Control`: ON/OFF switch to select automatic routing mode or manual control of the dimmer.
 - `Dimmer Level` / `Dimmer Level Manual Control`: Slider to control the dimmer level manually. Only available when the dimmer is not in automatic mode. Otherwise the dimmer level is displayed.
-- `Grid Excess Sharing`: Only available in automatic mode. Allows to share the available grid excess between outputs so that each output are activated and will receive a certain percentage of grid excess.
-  If output 1 is set to 100%, then output 2 will only be activated when output 1 is at 100%.
-  If output 1 is set to 0%, then output 1 will be skipped and all the grid excess will go to output 2.
+- `Grid Excess Reserved`: Only available in automatic mode. Allows to share the remaining grid excess o the second output.
+  For example, if output 1 is set to 50%, then output 1 will take at most 50% of the grid excess (eventually less if 50% of the grid excess exceeds the nominal power of the connected load). Output 2 will be dimmed with the remaining excess.
 - `Dimmer Duty Limiter`: Slider to limit the level of the dimmer in order to limit the routed power.
 - `Dimmer Temperature Limiter`: Temperature threshold when the dimmer will stop routing. This temperature can be different than the temperature used in auto bypass mode.
