£32 plus 3.68 pp

this kit is to convert the earlier version (pre May 2021) to the latest release which would make your atu so it will accept either the infrared or capacitive sensors


capacitive sensor

capacitive sensor mount w/magnet

programmed chip (IC) - the chip is not available on its own!


 no electronics skill is needed but it will require opening the controller and removing and replacing the programmed chip (mounted on a socket so a little care needed - see thumbnail)
