Digital messages in a load control system

A system controller for controlling a load control device configured to control an electrical load, the system controller comprising:

• a communication circuit configured to communicate commands for controlling the load control device;
• a control circuit;
• and
• a memory having instructions stored therein that when executed by the control circuit direct the control circuit to:
• in response to a first selection of a first preset, communicate a first command via the communication circuit to the load control device, wherein the first command comprises preset data that defines one or more operations of the load control device in response to a selection of the first preset and further comprises a preset identifier for referencing the preset data, the first command configured to cause the load control device to store the preset identifier and at least a portion of the preset data in a memory of the load control device, and to control the electrical load based on the preset data;
• store within the memory of the system controller an indication for the first preset that the preset data was communicated to the load control device;
• in response to a second selection of the first preset, determine from the indication for the first preset stored within the memory of the system controller that the preset data was communicated to the load control device;
• and
• based at least in part on determining from the indication for the first preset stored within the memory of the system controller that the preset data was communicated to the load control device, communicate a second command via the communication circuit to the load control device, wherein the second command comprises the preset identifier and does not include the preset data, the second command configured to cause the load control device to use the preset identifier from the second command to access the at least portion of the preset data from the memory of the load control device, and to control the electrical load using the at least portion of the preset data accessed from the memory of the load control device.
