Unable to find any firmware file for the KH Director, the current version for mine is version 1

Do I need to update firmware for the KH, if yes where can I please find the relevant file to download.

No need to update KHD, 1.00 is the latest.

Intelligence is in the Profilux (or SA doser), an update of the KHD itself has not been necessary until now
