Overview
The EnerVista 489 Setup software interface supports three ways of handling changes to
relay setpoints:
•In off-line mode (relay disconnected) to create or edit relay setpoint files for later
download to communicating relays.
• Directly modifying relay setpoints while connected to a communicating relay, then
saving the setpoints when complete.
• Creating/editing setpoint files while connected to a communicating relay, then
saving them to the relay when complete.
