Replacing the Room Stations

The remote and door stations use the existing wire and station rough-in mounting frames or boxes. To replace the station, first remove the old station. Leave the existing remote or door station rough-ins in place.

After removing the remote station verify the integrity of the wire run. Then install the mounting plate from the NF300RWH frame. Align the plate on the wall either vertically or horizontally so that the screw holes line up with those on the rough-in or box. Use a level to make sure the plate is level. There are several screw hole locations on the mounting plate so it can attach to many rough-in designs. Mount the plate to the wall using the screws provided.

Next connect the wires to the retrofit remote station. Match the wire colors to the corresponding screw locations on the NRS103WH or NRS104WH remote stations. Please make sure to use only NRS103WH remote stations in a 3-wire installation and NRS104WH remote stations in a 4-wire installation. All 6-wire installations use the NRS200WH remote stations. Please refer to appendix A for a diagram of which NuTone and M&S systems map to the 3, 4 or 6- wire (requires NM200 master) configurations. Refer to the following two charts for the NM100 wiring diagram:

Connect the remote station to the existing wiring using the diagrams above. Place the remote station through the NF300RWH plastic mounting frame. Position the frame either vertically or horizontally depending on the remote station replaced. Place the remote station into the rough-in ring and align the frame with the remote station.
