240616 Where are the DIP Switches?

There are two adjacent rooms. Each room has a fan (Cosa Alpha brand of unknown model) with its remote controller (GTM8 ALPHA CEILING FAN REMOTE CONTROL).

During installation many years ago, the contractor did not separate the frequency of the fans and now both of them respond to any of the two of the remote controllers whenever any one of them is pressed.

From the photo above, you can see that the DIP switches are set to the same pattern.

I am trying to locate the DIP switches on one of the fans in order to change it to a different pattern, and do the same to its corresponding remote controller.

Can anyone tell me which part of the fan are the DIP switches located?

    Some suggestions that I have gotten:

    – It is in part ‘A’.

    – Stand very close to the fan you want to control, and press the remote controller. The other fan would then not be affected.

    – Point the remote controller towards one particular direction, and it will not affect the other fan.

    – Take the fan down, remove the blades, open everything up and locate the DIP switches. This is a 2-person effort.

    – I have not seen this type of remote controllers before. But why do you want to adjust the switches? If they are same models, there are likely set to the same frequency. So I would try using another remote and see if the other fan reacts? (sic)

    Download cosa alpha instruction manual, it shows how to pair the fan’s receiver with the remote controller. I suppose you can set the dip switches of one of the remote controller to a different one and set the receiver of one of the fan to pair with the new frequency.

      There are too many versions of Cosa Alpha manuals. So far has not found any for this model. Many of them have their receivers in part A, the so-called ‘top canopy’.

      But this particular model has its receiver inside part C.

      Problem has been solved.
