If multiple controllers share power but polarity was not maintained when they were wired, the
difference between the controller's ground and the computer's AC power ground could damage the USB Link and
the controller. If you are not sure of the wiring polarity, use a USB isolator between the computer and the USB
Link. Purchase a USB isolator online from a third-party manufacturer.
Configure the chiller system
You must address and configure the chiller system before starting the 30MP Multi-chiller controller, which
supports a maximum of 8 chillers. The steps below enable the controller to communicate with each individual
chiller through their corresponding UPC Open. Once the system is powered and operating, the controller reads the
type and size of each chiller and automatically configures any additional features, such as hot gas bypass, that
could impact machine staging or sequencing.
•
You do not have to follow any special staging or addressing guidelines.
•
You must carefully implement the following staging and addressing instructions for
optimal water temperature control and part-load efficiency.
