It looks like you are trying to have one chiller loop serve two separate AHU's. When you use our templates to make a system type using plant loops everything comes pre-wired together. The screenshots below show how to hook a second air loop into the system.

While viewing the new airloop, grab a Coil Cooling Water object from the library and drag it to the supply side of your air loop. Notice how it doesn't have the dots above and below. That is because it isn't currently linking any loops together.

Next go to the chiller loop. This time go to "My Model" instead of "Library" and then drag the new Coil Cooling Water object to the demand side of the plant loop.

If you went back to the air loop you would now see the link made. You can also do this in reverse order. First adding to the plant loop and then the air loop.

Thanks so much David, that is was immense. However I have a follow-up question. I have the schematic but can not figure out how to upload it here so will put it up as a new question. Do kindly take a look. Cheers

You can't add images to a comment, but if it relates to this question, you can update it and add an image. But if this is a new question it is probably better being separate anyway.
