Ice Build Control

IMPORTANT: The Ice Build control option is only available on machines with PSIO Software Version 09 and higher.

Ice build control automatically sets the chilled WATER/ BRINE CONTROL POINT of the machine to a temperature where an ice building operation for thermal storage can be accomplished.

Note: For ice build control to properly operate, the PIC controls must be placed in CCN mode. See Figure 16 and Figure 17.

The PIC can be configured for ice build operation. Configuration of ice build control is accomplished through entries in the Config table, Ice Build Setpoint table, and the Ice Build Time Schedule table. Figure 16 and Figure 17 show how to access each entry.

The Ice Build Time Schedule defines the period during which ice build is active if the ice build option is ENABLED. If the Ice Build Time Schedule overlaps other schedules defining time, then the Ice Build Time Schedule shall take priority. During the ice build period, the WATER/BRINE CONTROL POINT is set to the ICE BUILD SETPOINT for temperature control. The ICE BUILD RECYCLE OPTION and ICE BUILD TERMINATION entries from a screen in the Config (configuration) table provide options for machine recycle and termination of ice build cycle, respectively. Termination of ice build can result from the ENTERING CHILLED WATER/BRINE
