[QUOTE="Tom78, post: 464207, member: 30184"] I am getting a phone like noise emitting from the Cupboard where my Vailliant EcoTec boiler is installed. The boiler has been checked by Vailliant and nothing was found. The noise is intermittent. The Condenstat has been changed due to horrible noise and while that noise was cured the phone like noise still occurs. I Have a Digistat 1RF Thermostat working with a DigistatSCR. Alongside the SCR is a Honeywell ST9400C Programmer' Close to the Cylinder is a small unit labelled as V4073A1039 Do not know what this is. Any help regarding the reason for the noise would be appreciated [/QUOTE]
