Hi, I just signed up to build hub today and I can already see someone who I can help!! I am a ventilation engineer who has now solely concentrated on installing, domestic ventilation for the last 7 yrs and had the luck to be involved in many different applications of nearly all the products that are currently on the market. I have had a few issues with itho advance but luckily I had a stock of replacement fan modules. I havn't touched them in 5yrs but I'll dig em out and give them a thorough functionality check. They are unused (as new), so I can help by getting a replacement to you sharpish and get your system back up and happy. I'm based in Anglia but am quite proficient in my explanatory skills to help you solve this issue remotely. Let me know if I can help. Scott 07586 993232
