parameters embedded in the software to simplify assigning heating cable circuits. The application
designs and assumptions are detailed in their associated design guides and installation manuals
which can be found on www.nVent.com.
The control mode functions programmed in the ACS-30 for each application are summarized in
Table 1.1. These control modes will be discussed in more detail in the configuration section of this
programming guide.
