Press the button and keep it down for 5 seconds, the control will change to show flash codes. The flash code is shown at intervals of 2 seconds, to return to “reset mode” press the reset button and keep it down for 5 seconds. The control is reset by pressing the reset button shortly. Note! It is only possible to reset the control in “reset mode”. When reset, the control will try to restart, but if the fault still exists or a new one has occurred, the control will lockout again. In the event of under-voltage, the control will take up a waiting position. This is indicated by a flash code of 8 flashes from the press button. When the voltage is within the work area, the flash code stops and the control starts as normal. Setting the box to diagnostics
