I put this one in my 195RB Hengs Vortex reversible, multispeed fan

No changes to outside lid, did from inside. Works great!
Took me longer to read instructions and gather tools then the actual install.
No big deal to fish wire but took a while to figure how to get ceiling light out and test hot before connecting.
Spouse held fan up while I made connections and tested. Then handed me screws and screwdriver while I held it in place.
