Operation and Installation Instruction
The WiTi Wireless Electric Brake Controller plugs into a standard 12V
cigarette lighter socket and includes an LCD screen and a dial for gain
adjustment and manual override. The WiTi Wireless Electric Brake
Controller is supplied with a separate WiTi Communication Module
that must be connected to an existing Anti-The Unit in the caravan or
trailer. Locate the Communication Module next to the Anti-The Unit
and connect with the supplied RJ45 cable. There is a corresponding
connector at the bottom of the WiTi Anti-The Unit and the side of
the Communication Module. The Communication Module is used
to wirelessly transfer the lighting and braking signals from the WiTi
Wireless Electric Brake Controller to the Anti-The Unit and then on to
the lights and brakes of the caravan or trailer.
The WiTi Wireless Brake Controller Unit has a functional display LCD
screen that displays the Trailer Battery Voltage, % Braking that will
be applied and the linked status. There is also an emergency Brake
Override button supplied in case emergency braking is required.
The WiTi Brake Controller is a proportional controller that applies
braking to the caravan or trailer in proportion to the rate of deceleration
plus it oers two signicant safety innovations - Hill Descent Assist and
Brake Smoothing.
Hill Descent Assist improves safety and control when descending steep
hills. All proportional brake controllers use inertia to determine the
braking force applied to the brakes. The rmer the braking the more
inertia is generated and braking is applied on the caravan or trailer in
proportion. However, when descending steep hills the driver of the tow
vehicle typically feathers the brakes to maintain speed - this generates
no inertia as there is no deceleration. As a result there is no braking
applied to the caravan or trailer and the tow vehicle is being pushed
down the hill. WiTi Hill Descent Assist eliminates this by measuring the
angle of descent and applying the brakes relative to the gain setting
on the dash mounted dial. The steeper the descent the more braking is
applied resulting in a safer more controlled descent.
Brake Smoothing eliminates the sharp and annoying jolting that
may occur with other brake controllers. With WiTi the output to the
