Description Class DimmableControlledLight

INTENTION

This description class provides all definitions of sensors and actuators relevant for the control of a dimmable light. This installation includes in addition to a controlled light:

• a dimmer, i.e. an actuator for the control of the illuminance of the light if it is on (object dimmer).
  Note that this dimmer can not switch on or off the light, i.e. even if the dimmer value is zero the light can have the status on, i.e. the circuit of the light is closed. Thus, the dimmer sets the illuminance in the case that the light is on.
