3. Upgrading to OS 2.5.2
Follow the recommendations in this section if you have an older system that uses Embernet, and you
want to upgrade that system to ZigBee Pro with the latest release.
3.1 Update Recommendations for Existing Systems
IMPORTANT! (1) The OS 2.5.2 release utilizes ZigBee Pro for ZigBee RF communications.
Controllers and ZigBee firmware devices upgraded to OS 2.1 or later cannot be downgraded to
Release 1.7.4 or prior versions. (2) A few legacy products are not supported in OS 2.5.2. Other
products are supported, but may have limited functionality or may not provide access to new
capabilities. For a current list of products and lifecycles, see
http://dealer.control4.com/dealer/support/product-lifecycle.
Control4 recommends that customer systems running OS 2.0.x or 2.1.x be upgraded to OS 2.5.2 if
they need any of the improvements included in this release.
1. Control4 recommends that customer systems running OS 1.8.2 be upgraded to OS 2.5.2.
Control4 no longer provides any support for OS 1.8.2.
2. Control4 will continue to support Release 1.7.4 for existing customers for a limited time.
Please use Composer 1.7.4 to manage projects running on Release 1.7.4. Other versions of
Composer may introduce incompatible drivers or project settings.
3. Control4 no longer provides support for versions of software prior to 1.7.4. We recommend that
these systems either be left “as is” or be upgraded to OS 1.7.4 or to OS 2.5.2.
Control4 will not provide new or replacement hardware products for prior versions.
Customers may continue to run prior versions for as long as they want. However, Control4
Technical Support has limited ability to answer questions and provide assistance for older
product releases.
Release 1.3.2.442 was the final release of the Release 1.3.x product line. While Control4
doesn’t actively support this release, it is the best/final release of this line and may be
considered as an option for customers who are using a Home Theater Controller or a Media
Controller as the primary controller within their system.
Customers’ systems running Release 1.6.0 or any 1.7.x release should be upgraded to
Release 1.7.4 or to OS 2.5.2.
IMPORTANT! OS 2.5.2 is a complete system software release. All supported Control4 devices
will receive new software or firmware. The update process will affect all devices in the Control4
system.
