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 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 offers two significant 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 firmer 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
electric brakes on the caravan or trailer is measured and smoothed
electronically to provide a more comfortable and safer towing
experience and eliminate harsh jolting.
To adjust braking sensitivity the dial can be turned to the left to reduce
trailer braking or to the right to increase trailer braking, the LCD screen
will display the new setting as a percentage gain that will be applied.
Adjust the brakes to a level where trailer braking is felt to assist with
overall braking of the tow vehicle and caravan. Different trailer weights
and driving conditions will require different settings to provide safe
