The v4 handset on my EQ3 has blown. Likelihood is that the previous owner connected a battery directly to the motor control box and had the polarity reversed. I think I can fix the handset (voltage regulator and a couple of caps) but when I plug another handset or even a Wifi module directly to the MCB, they are not recognized. Has anyone had a problem with their EQ3 MCB and if so, what was the problem/solution. Thanks, Philip
