I'm getting confused, sorry.
You have to tell me abit about the system. Most of the fan remotes are RF based with a module mounted in the fan. Some are add on and others are buit in.
Many times homes are wired with power to the ceiling fixture and a two conductor wire becomes a switch loop.
Usually, and I think it's stupid, only the remote can be used and you cannot use two remotes at the same time.
There is the IR version like I've eluded too.
You sort of mentioned that there was no fan. Is there a fan now?
What basically confuses me is
1. A hampton bay wireless remote
(implies a receiver in a fan and nothing in the switch n the wall)
2. Using the switch an remote at the same time
(generally implies an IR remote with somethig on the wall that you aim at)
3. Any markings? Picture of this thing. Model numbers?
4. Are you trying to use a fan this time. *without 3 wires heading to the ceiling fixture it won't happen)
I also don't know, what, if anything you have for troubleshooting: A meter, a test light etc.
I don't quite undersatnd two wires for the fan. Are any labels present on the wires?
If this thing is something that's mounted in place of the switch and it's an IR receiver and your not using the fan, then the hookup should be straightforward.
1. Remove the wires to the switch
2. Identifying power would be first on the agenda. It likely comes in at the bottom. Measuring between whaite and black with the switch off is first on the agenda.
3.Black and white of the control unit would go to the identified power.
4. Blue would go to the light. The fan wires would be capped.
Esentially, it would look the same as before except there would be more wirenuts and there would be 3 white wires together.
