Only been running the KHD for three weeks and yesterday got a one-off higher reading moving from a consistent 8.2 to 8.5 and then suddenly jumped to 9.1 from 8.2 over an 8 hour period and then gradually back again to 8.2 in just over 24 hours.
Anyone any ideas why this would occur as there is no changes been made within the system and I have not yet got control set up. - see screenshot
