In-Wall remote Control

Bought three fans abd chose this add-on in wall control for each one (wanted this instead of a remote control stuck to the wall). The problem is once all three fans were installed and these were all wired up, the controllers are NOT dedicated to the fan they are wired to! Using one of the these actually controls multiple fans, which is super frustrating. If we change anything in the bedroom, the hallway fan is changing along with it. We are still waiting to hear from Arranmore. Besides the 0-1 toggle on the wall unit before you install it, there are no pins you can change to set each control to a unique ID. If we can't figure this out, then I recommend nobody buy this if you plan to have more than one fan on any given floor of your home (unless you *want* all your fans responding to all the controllers all the time).
