    Have you called the tech support number yet or the people that sold or installed it? And if you swap the inlet with the outlet sensor does it fault out to the outlet of chilled water. If you end up ordering 1 and they are the same order 2.

    And you reset the power? I would get a hold of the place that has these parts and or service. If all the sensors are the same order a couple of them. And do the other comps work or our you dead in the water,so to speak. If so you need to get a hold of tech support. ASAP

    Ramzan i do not know what else i can help you with on this. One of our members named moideen Yousaf, allows lives in Dubai. I sent him a message to see if he may be of some assistance. Get your post count up, then apply for professional status on this site. I t will open up a lot more info and contacts than you have now. I will try to look up that manual you have, i would think that you would only have 1 water sensor for the inlet and outlet that goes to the main board. Then the comps would use that for staging purposes.
