We have encountered some unwanted and disturbing noise on our ZoneDirector, the noise lasted for around 2 hours but stopped on itself. Please see my shared link of the video taken during the incident: https://drive.google.com/open?id=0B2EPe3bdUiyAa054aUl6Mmt2SFU

Could anyone please tell me what's wrong with our unit? What can we do to prevent this to happen again..

Nice vid!
You are absolutely certain the noise emanates from the ZD (and not from kit above)?

Sounds like worn fan bearings on the way out. Believe a ZD3000 has 2 fans at back of unit.

Suggest query tech support and get replacement unit.
