[EnergyPlus_Support] Separated zones Branch input



I have problem about Branch input.
Now, modeling 2zones serving fancoil and desiccant separately.
In branch input, some messages showed up below.

** Severe  ** Non-unique node name found, name=PURCHASED COOLING

   **   ~~~   ** ..1st occurence in Branch=PURCHASED COOLING BRANCH

I think that I must use a only one node name at the Branch.
Then, How can change the node name of the second branch input?
