boolean ZW_ShutterMoveDown (int $InstanceID)
ID of the device to be switched
If the command succeeds, it returns TRUE, otherwise FALSE.
Moves the shutter with the ID InstanceID downwards until MXC_ShutterStop is running or the end position is reached.
Note that some blind control from Z-Wave must be adressed over ZW_DimSet like the dimmer.
ZW_ShutterMoveDown(12345); //Move downwards
