Today, I identified that the upstairs EIM (Equipment Interface Module) had failed, impacting the system’s ability to function properly. I replaced the faulty EIM under warranty and then thoroughly cycled the system to ensure everything was operating smoothly. After the replacement, I confirmed that the system was functioning as it should, restoring full comfort and efficiency to the home.
