3. Harmony 380/380SE operation & care
3.1 Harmony 380/380SE System
• The Harmony 380/380SE system is
compatible with NuVinci Optimized N360
and N380/380
SE series CVPs (but is
incompatible with the NuVinci Optimized
N330/N330f CVP).
• The Harmony 380/380SE system utilizes
the Harmony H8 controller, which offers
both fully automatic and manual shifting
options. The rider switches between
“automatic” and “manual” modes by
pressing the “mode” button (A) on the H8
Controller housing.
• In automatic mode, Harmony 380/380SE
automatically adjusts ratio to maintain
the rider’s preferred cadence. The rider
can choose their ideal cadence setting
by rotating the grip. The blue LED “RPM”
display indicates the cadence setting (B).
• In manual mode, the rider is able to
shift on their own with “ride by wire”
technology. Like the cable-shift system,
the steeper the orange “hill” on the
LED display (C), the easier the ratio for
climbing.
3.2 Calibrating the Harmony 380/380SE
System
If the Harmony system has been reinstalled, or
if system operation is inconsistent or incorrect,
your Harmony 380/380
SE system may need
to be calibrated.
To do this:
1. Turn system power on.
2. Pedal the bicycle lightly through the entire
calibration procedure (preferably on a
stand with the rear wheel off the ground).
3. On the Harmony H8 controller, press and
hold the “mode” button (A) until the rear
hub begins shifting (5-7 seconds typically),
then release the button.
4. Continue pedaling lightly while the system
shifts from “low” to “high” ratio multiple
times and completes calibration.
HARMONY 380 OPERATION & CARE
The NuVinci Optimized CVP cannot
be shifted completely through the
ratio range when stationary. The
Harmony system will intelligently wait for
pedaling or wheel movement if wide ratio
ranges are commanded while stationary.
