OpenStudio allows you to place multiple daylighting control objects in a space for use with Radiance. You can also combine multiple spaces into a thermal zone. Therefore, OpenStudio makes you specify the daylighting control at the thermal zone level for simulation in EnergyPlus. For EnergyPlus simulations, only the primary and secondary controls are exported to EnergyPlus. EnergyPlus recently dropped the restriction of 1 illuminance map per zone so OpenStudio will likely deprecate the method that points from thermal zone to illuminance map and will export all illuminance maps to EnergyPlus as they are to Radiance.
