l Always keep device on: Select the check box to prevent the device from turning off after
60 seconds. The default for Always keep device on is disabled.

NOTES:

Existing devices in upgraded systems will have "keep sources on" disabled to maintain
their current functionality in Pyng. The Installer can then enable it as needed.

When Always keep device on is disabled:
o Keep device on when not in use is disabled by default.

o Startup behavior:
n For sources with power state feedback, the source power state is set to
reflect the current source power state (on or off).
n For sources that do not support power state feedback, the source power
state is assumed to be off.
n For sources that do not have power commands, the source power state is
assumed to be on.
o If the source is off when routed, then the source will be turned on using either the
discrete Power On command or the Toggle Power command.

o If the source is no longer routed to any room, the source is turned off after 60
seconds.
When Always keep device on is enabled:

o Startup behavior.
n For sources with power state feedback, if the source is off then it will be
turned on automatically. If the source is on, no action will be taken.
n If the source does not have power feedback and supports discrete power
commands, the PowerOn command is sent to the device and the power
state is set to on. Turning the source on at startup minimizes the wait-time
for the device to warm up.
n If the source does not have power feedback and only supports toggle power
commands, the PowerToggle command is not sent to the device and the
power state is set to on. This prevents a source that is on from being turned
off. If the source is not on, the user can turn on the source in the Crestron
Home user interface.
n If the source does not have any power commands, the power state is set to
on.
o If the source supports power feedback and is off when routed, the source will be
turned on. This can occur if the source was manually powered off.
o If the source is no longer routed to any room, the source remains on.
