Anyone know if there is a special factory reset operation for these? Installed a used HRD-10D the other day and although it operates as a dimmer, has a serial number, and its sticker displays the HRD-10D model number, the triple tap process does nothing during addressing and the triple tap and hold method of resetting it is unresponsive.. Almost like the control brains of the unit are gone? Just seeing if I'm missing something before I toss it i the garbage!
