ABOUT THE TREK3

The Trek3 is a wall-mounted smart battery monitor designed specifically to operate with BMPRO’s BatteryPlus35.

The Trek3 provides vital data at a glance including caravan battery voltage and charging/discharging current. The Trek3 also provides an indication of the battery’s remaining charge capacity as well as the time remaining before the battery completely discharges – so you’ll never be left on the road without battery power.

In addition to battery monitoring, the Trek3 enables monitoring of water levels of up to four water tanks and control of two water pumps, all from a sleek, wall mounted display.

The Trek3 can be connected to the included OdysseyLink103 to become part of the Odyssey system. Once connected to the OdysseyLink103, you can use BMPRO’s free Odyssey App to remotely monitor your battery and control your caravan’s water pumps from your smartphone!
For more information about Odyssey, refer to your Odyssey Owner’s Manual.

OPTIONAL ADD-ONS

To get the most out of your Trek3, it may be used with the following products from the BMPRO range:

FAQS AND TROUBLESHOOTING

Need more help troubleshooting your Trek3?
Contact our customer service team online at teambmpro.com/technical- support

Why has the Trek3 screen turned off?
The Trek3 receives power to run the monitor from the BatteryPlus35. If the BatteryPlus35 shuts power to the monitor, the Trek3 screen will turn off. The BatteryPlus35 will shut power to the Trek3 if:

1. The user activated the load isolation switch connected to the BatteryPlus35. This turns off power to the data cable connecting the Trek3 and BatteryPlus35. Check that the switch has not been activated.
2. The BatteryPlus35 has entered Storage Mode and to conserve remaining battery voltage will disable power to the Trek3. To re-power the Trek3, plug the BatteryPlus35 to a power source and begin battery charging. When the battery is sufficiently charged, the BatteryPlus35 will enable power to the Trek3.

Why are the battery volts and amp flashing on the Trek3?
Battery volts and amps will flash on the Trek3 if a BC300 + CommLink external shunt has been installed and communication with the shunt has been lost.
Use the advanced menu function to clear the external shunt from memory and re- establish communication with the BC300 + CommLink. See the Appendices for more details.

I have water tanks, but they are not showing up on my Trek3?
If your Trek3 is connected to the OdysseyLink103, then the water tanks also need to be connected to the OdysseyLink103 for them to show up.

APPENDICES

ADVANCED MENU FUNCTIONS
