NOTE: If Local start is not desired then Auto Start needs to be
configured for user to start as per user configurations. User login
or higher is required to access the "Configure Startup Options"
Menu. If Network start by CCN, BACnet or Modbus or if remote
contacts are to be used for startup they will need to be enabled in
the startup menu. To stop chiller each enabled start option must
send a stop command.
When a start-up is initiated, a status screen displays the progress of
the start-up sequence. See Fig. 13 and 14.
