astral mains controllers are available in 1 and 2 gang versions and are suitable for flush or surface mounting in
BS wall boxes with a minimum internal depth of 35mm and should be mounted in dry indoor locations only.
A mains controller can provide on/off control over switches and in addition on/off and dimming control over dimmers to operate together as a group. Alternatively it can be used to control a scene where the user configured light levels are recalled to set a required lighting mood.
