Can anyone explain how this works....Part L of the building regs states that 'fan coils' should have a specific fan power no more than 0.8w/l/s (other items are listed) but how does this relate to VRF/VRV; Multi split etc ducted fancoils? do they have to comply, and if not, why not, what defines a 'fancoil' The system i want to use is neither of the above, but similar to both, but i need to know how it fits in with Part L.

Any ideas?
