Due to numerous requests I decided to describe the recovery procedure for our controllers. Recovery mode allows you to bring controller to out-of-the box state, with the firmware version it was shipped with to you. There is no way to go back to version older that the one you got device with originally.   Entering recovery mode on Home Center 2:   1. Unplug your device from power.   Please login or register to see this attachment.   2. Hold down the recovery button (with a little "+" on it )
