Overhead Ceiling Fans

All Remaining Fans
1. Set dipswitch 2 as shown below. Dipswitch 2 is
used to set parameters that improve network
function and will need to be adjusted for all fans in
the network except for the first fan.
Position 1 – Off
Position 2 – Off
Position 3 – Off
2. Adjust positions 1 – 5 on dipswitch 3 so that each
successive fan has a unique Modbus address. A
table with all possible Modbus addresses is shown
to the right.
IMPORTANT:
Positions 6 - 8 are used to set parameters
needed for fan operation and should not be adjusted.
Default settings are as follows:
Position 6 – On
Position 7 – Off
Position 8 – Off
NOTE:
It is good practice to use successive Modbus
addresses for networked fans, but this is not necessary
for proper functioning of the network.
3. On the low voltage wiring terminal strip, remove
the 24V (white-brown) wire and cap with a wire
nut or heat shrink. When complete, verify that the
low voltage wiring terminal strip on the VFD circuit
board is wired as shown in the diagram and picture
on pages 38-39.
4. Reinstall the black plastic cover that was previously
set aside on the front of the VFD.
