FORM 160.78-CL2 B. CONTROL PANEL: Login at SERVICE level access to ensure access to the necessary setpoints. The setpoints are grouped by the screen in which they appear. Enter the as-left value in the corresponding box for each setpoint. Some are ADMIN-controlled chiller configuration and factory defaults that should not be changed. Those that cannot be changed in SERVICE level access are identified with (ADMIN) after the setpoint name and are intended only to be validated and logged at SERVICE level. Those with recommended settings for proper operation are designated with the setting in parenthesis after the setpoint. Others do require specific setup for the site conditions and consideration of the application. Those most likely requiring site-specific setup are marked with italic text. Ensure each setting is logical for the chiller configuration and application. Refer to forms 160.78-O2 and 160.78-M2 for procedures to perform calibrations or explanation of setpoints. Start by navigating to the Capacity Control - Setpoints Screen and accept the default capacity control and level control setpoints with the DEFAULT SETPOINTS button on the bottom bar.
