This is the programming remote control required to set up your Microwave Sensors when used with the 100 - 200w UFO LED High Bay - CCT fittings. If you are installing the high bays to be controlled via a manual switch (on/off) then you do not need this remote control. This is only required if you are running microwave motion sensors on your fittings. For use with the HBOMU UFO LED High Bay range only.
