This article details why you may or may not receive a new cover bundled with a replacement Energy Management System (EMS).
The following products are discussed in this article:
- Legacy: R920 and R247-E
- E Series: R920-E, R820-E, R829-E and R247-E
- F Series: R920-F, R820-F, R829-F and R247-F
The following are two scenarios that you will come across when receiving a replacement EMS:
- Standalone EMS, ready to be mounted to the existing EMS cover
- EMS mounted to a new cover
EMS with Cover Standalone EMS
The new cover is required for systems older than ~2018 Q3. An update to the EMS increased its physical footprint and the cover was also updated to accommodate this. This will allow for a seamless installation process. Newer style systems that already contain the proper size cover will not receive a new cover.
|Model||Date of Manufacture||Cover Included|
|Legacy: R920, R247-E||2018 Q2 or older||Yes|
|E Series: R920-E, R820-E, R829-E, R247-E||2018 Q3 or newer||No|
|F Series: R920-F, R820-F, R829-F, R247-F||2018 Q3 or newer||No|

For older systems we highly recommend preventative maintenance on the ambient brightness sensor cover. For more information see our support article here for our latest drop-in replacement.
When requiring a replacement EMS be sure to advise Carmanah or your distributor the serial number of the original system to correctly match the vintage of the system and any programming that may be required.
