You can reset to factory defaults by holding he middle button while turning on the unit. However error 2 is a driver fault. That is usually a sign of physical damage. If the board was wired wrong that is how it was damaged. If the problem goes away after fixing the wiring you got really lucky. I will assume it does not go away though. In that case you need to send the unit in for repair. The charge will be minimal if it is just the mosfet driver that is damaged. Make sure to include a note inside the package with your contact information and return address.
