Alde main circulation pump circuit board on back of motor burnt up M/N D5vario 38/000 S/N50371977. There is 12v power going to this motor all the time when battery switch is on. The Alde 3020 controller is not controlling power to this pump. That's why it burnt up. There is power to the pump when the wire from the 3020 is disconnected at the board at the boiler. My thought is; there is a relay on the board that is bad stuck closed to power the pump. Anybody had this problem? Or other ideas. Sincerely Tim Tab 400 BB 2022 Alde M/N 30209300 S/N 371145
