Generally the master and remote controllers should run the same firmware because the firmware APIs are not always the same across different firmwares. They must also have the same device password. Also, the communication is one-way: that is, only the master controller sends command to the remote controller, the remote controller does NOT send status update back to the master. So you can only turn on zones on remote controller from the master; if you turn on zones on the remote controller itself, it cannot send the status update to the master, so it won’t be reflected on the master controller.
