Hi guys,

I have KH director that stoped working 17 days ago and still shows on the app that my readings 7.6 dkh which im happy with. I havent noticed that last check was done about 17 days ago and if i press test now, vent regent line or other two test button its not activating and doing nothing. Tested all cables, doser heads individually and works fine. Nothing changed since last time i set it all up. if i activate KH director pump and valve i can hear them working.
Any advice welcome

Regards
