Chapter 17—Restart
4 The Home Control Assistant
The restart options for the device allow you to control restart for just this device. Similar options
are available from devices, programs and groups.
Restart from a normal shutdown
Up until now all the discussion has focused on restart after a power failure. What is different when
starting after a normal shutdown? Almost nothing. HCA still has a state file that is marked with
the time of the shutdown. That state file contains the state of all devices, the current schedule, all
the values of the flags, etc.
When HCA starts after a normal shutdown it proceeds as described above. That is, it catches up to
where it would have been if it had not been shutdown.
Restart from a normal shutdown must be enabled as one of the options on the Startup tab as shown
above.
Some final information about power failure and recovery
Here is some additional information about restart
 Restart is a very complex subject and this brief explanation is discussed in much
more depth in a technical note on the support web site.
 Power failure recovery is so complete that you may not notice that power has failed while
you were out. Check the log—entries are made when power fails and when it is restored.
 If you are using an uninterruptible power supply, make sure that you power only the
appropriate parts of the interface hardware from the UPS. Refer to the Hardware
Connection Guide for information on the interface hardware that you are using.
