*Dashes are displayed for the setpoint when the chiller is not in the “Ice Building” or “Ice Building Complete” mode.
**The UCM will permit only one type of reset (Return, Zone, or Outdoor) to be selected at one time. For example, if Return
Reset is enabled, an attempt to enable Zone Reset would disable RETURN RESET and enable Zone Reset automatically.
***The UCM contains setpoints for each of the types of reset. The setpoint displayed will be for the type of reset enabled.
If no reset is enabled, dashes will be displayed.
