You can dim the lights using touch control or remotely .
The master dimmer switches are one way but can be used in conjunction with slave units
in a multi-way circuit (including intermediate and 2 way)
so that the lights can be dimmed from more than one location.
In this type of circuit you should use one master dimmer and any number of slave units
with three wires directly connecting each switch (as is usual in a 2 way circuit).
