NuTone NM100 Serie Manuel D'installation page 4

For the NWH300C Master Station and CD combination rough-in,
have a qualified electrician loop a power wire from the NA200TA
transformer enclosure to the NA300TA transformer enclosure
following the same procedure described previously and shown in
the next figure.
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.
