The kit includes:
1x Fan TT100, 2 speeds, 147-187m3/h
1x HY-FILTER 100mm 250m3/h
1x Ventilation duct 102mm, 1m
1x Plug with cord.
For an extra 400kr, you can replace the fan TT100 in this package for a fan TT100 with a built-in digital fan controller.
To change the speed of the fan, just change the cord's position between L1 and L2.
The cord attached to the N will always be there and you should never have L1 connected at the same time as L2!
