how can i switch one fan independantley from 2 separate rooms?

You need to use a 2 way switching system where the power is transfered to each of the switches. You need live feed to one of the switches (top) and a switch wire to the fan (brown) from the other switch (top) between the two switches u must have strappers a pair of brown cables. 1.5mm 2 and you need a neutral to your fan and a permanent live feed if a timer model.
