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 the case of emergency braking being 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 Control and Brake Smoothing.  Hill Descent Control 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 Control 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 braking operation on the trailer. Experiment with the settings to determine the ideal braking settings for your trailer or caravan. Braking to the trailer or caravan can be applied manually by pressing the brake controller dial. This will apply braking at the level indicated on the LCD screen. Turn the dial to the left for less braking and to the right for more braking. In manual mode Hill Descent Assist and Brake Smoothing are disabled.

Pairing a WiTi Wireless Electric Brake Controller to the WiTi Anti-Theft

System

1. Ensure the WiTi Anti-Theft System is powered on and within 10 meters of the WiTi Wireless Brake Controller.

2. On the WiTi Anti-Theft System press and hold the PAIR Button.

3. While the PAIR Button is still depressed, press the RESET Button for half a second and then let go of the RESET button whilst still depressing the PAIR Button.

4. When the RESET button is released, you will notice the red LED flashing rapidly while the amber LED is still solid. Let go of the PAIR button. The WiTi Wireless Communication Module is now in PAIRING mode. The unit will stay in pairing mode for five minutes while searching for a WiTi Wireless Brake Controller to connect to.

5. While the WiTi Wireless Communication Module is in PAIRING mode, retrieve the WiTi Wireless Brake Controller. Turn the ignition in the tow vehicle on to ensure there is power available at the 12V cigarette lighter socket. Press and hold the emergency Brake override button on the WiTi Wireless Brake Controller. While the Brake override button is still depressed, insert the WiTi Wireless Brake Controller into the vehicle 12V cigarette lighter socket.

6. The WiTi Wireless Brake Controller LCD Screen will now display the “Pairing Successful” Message. You can now release the Brake override button. The “Pairing Successful” message will display for 5 seconds and then the WiTi Wireless Brake Controller will exit PAIRING Mode and return to normal operation. The Battery Voltage and Linked Icon will now also be displayed.

7. On successful power and pairing the WiTi Anti-Theft LEDs will flash simultaneously for 5 seconds to indicate that it has successfully paired with the WiTi Wireless Brake Controller. Once the LED’s stop flashing the WiTi Anti-Theft will exit PAIRING Mode and return to normal operation. Both the Amber LED and the Red LED will now be illuminated while the WiTi Wireless Brake Controller is within wireless range of the caravan / trailer.

8. If the Anti-Theft System unit did not detect a PAIRING partner during the pairing sequence, then the red and amber LEDs will flash in an alternating sequence for 5 seconds. This indicates that pairing has failed and the unit will then return to normal operation mode with just the amber LED illuminated.

9. If the WiTi Wireless Brake Controller did not detect a PAIRING partner during the pairing sequence, the display will show a message reading, “Pairing Timeout” followed by a message “Pairing Failed”. Repeat the pairing.

Brake Controller Brake Calibration
The WiTi Wireless Brake Controller integrates with the WiTi Anti-Theft Unit installed in the caravan or trailer. The WiTi Anti-Theft Unit should be installed vertically and facing either to the front or the rear of the caravan or trailer. The WiTi Break Controller uses input from the accelerometer located in the trailer unit and uses gravity as a reference point for calibration. The WiTi Trailer Unit is calibrated at factory however, in the event it requires re-calibration or the installation or caravan / trailer is not level when hitched, please follow the following steps:

1. WiTi must be paired and linked status on the LCD Screen must be lit indicating a paired state
2. The Caravan / Trailer must be stationery (any movement will prevent the calibration)
3.  The Caravan / Trailer must be on a level surface (if not level a faulty calibration will result)
4. Turn the dial to the left until it displays 0 then press the button. The Menu screen will appear
5.  Use the dial to highlight “BRAKE CAL” and press the button. The screen will display “Brake Calibration in progress” followed by “Calibration Successful”.

Brake Controller Voltage Calibration
The WiTi Wireless Brake Controller displays the voltage of the batteries in the caravan. Occasionally the voltage displayed may be different to the actual voltage in the caravan and a calibration is required. To calibrate the Brake Controller voltage to the caravan battery voltage.

1. Turn the dial to the left until it displays 0 then press the button. The Menu screen will appear
2.  Use the dial to highlight “VOLTAGE CAL” and press the button. The screen will display the voltage. Adjust the voltage up/down by turning the dial. When the voltage is correct press the button and the screen will display “Volt Calibration Successful”.
