I was installed this past December with a Genie HR44. They have the SWM/Swim, whatever it is called hooked up downstairs while my HR44 is upstairs in the living room. I believe when it was installed, the technician told me the HR44/HR54 are hooked up differently. So, I've been experiencing a few issues with my current HR44 with it slowing down and some other things. I called in to tech support a few days ago and they set up to ship me a replacement receiver.. Well, they shipped me a HR54 instead of a HR44.. I'm wondering if I can just plug and play by disconnecting the HR44 and plugging in the HR54 with the Swim setup still going downstairs? I know the HR54 has it built in so that's why I wasn't sure if it will work properly with this current setup.
