1. Remove the front VFD cover using a phillips
screwdriver.
2. On the communication wiring terminal strip,
remove the 24V (brown-white) wire and cap with
a wire nut or heat shrink. Additionally, remove the
stranded silver drain wire that is attached to the
circuit board mounting screw and isolate from all
circuit board components using heat shrink.
IMPORTANT: If touchscreen control was provided with
the optional temperature/humidity sensor package,
do not remove the 24V (brown-white) wire from the
communication wiring terminal strip on the last fan
in the daisy-chain (furthest fan away from the control
source).
3. 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
4. Adjust positions 1-5 on dipswitch 3 so that each
successive fan has a unique Modbus address. A
table with possible Modbus addresses is shown
below.
IMPORTANT: Positions 6-8 are used to set parameters
needed for fan operation and should not be adjusted.
NOTE: It is good practice to use successive Modbus
addresses for networked fans, but this is not necessary
for proper functioning of the network.
5. Reinstall the front VFD cover.
