astral dimmers are available in 1 and 2 gang versions for connection and control of 1 or 2 load circuits. They 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. Each astral dimmer also has the capability to control up to 5 other switches and/or dimmers. It will provide on/off control over switches and 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.
