Bonding a Truma AR2 handset to control panel
Check that you have power from the caravan leisure battery to the control panel.
Press & release the small reset button on the rear right of the control panel, a green light should start flashing rapidly.
Press the red button on the handset twice, the red light should light up on the handset.
There should be a series of clicks from the control panel, the handset should now be bonded & the green light should now stay on as a solid light, so switch off the handset, wait 5 seconds, then switch handset back on with a double click of the red button, the control panel should issue several clicks & switch on with a solid green light, try the mover buttons to test it without engaging the rollers to the wheels.
If it didn’t work, remove a battery terminal for 5 minutes to totally kill power to the control panel, then refit it & try the above instructions again, if it still doesn’t work there are several reasons why not, the main cause is battery power too low, so charge the leisure battery with a proper car, or better still a leisure battery charger, but do not boost charge, only charge at under 6 amps max.
Check the terminals on the battery & connections to the control panel to see if they are good & tight & clean.
If all else fails then the receiver in the control panel could have gone down or the handset could be faulty or its battery is low.
