Spreading across the range is the revolutionary multi-coloured roof lighting, more commonly known in the industry as Chromotherapy lighting. The Chromotherapy lighting is model dependent so please check the specifications of your model to ensure it has it.
To operate the multi-coloured lighting you turn on the control panel. The lights will automatically come on, then you press the light function and wait. After a few seconds the lights will begin to scroll through the colour options. Once you are happy with the colour option and you want to stop the colours scrolling you press the light button again. Be vigilant the panel hasn't locked in the meantime because if so the light button will not work whilst in lock mode.
You can see the operation of Chromotherapy lighting in a tutorial video below.
