Ice Build Control
Ice build control autom at ically sets the chilled W ATER/ BRINE CONTROL PO INT of the
machine to a temperatu r e whe re an ice building oper at ion for thermal storage can be
accomplished.
Note: For ice build control to pr ope rly operate, the PIC con trols must be placed in CCN m od e.
See Figure 16 and Figure 17.
The PIC can be configured fo r ice build op eration. Config uration of ice build control i s
accomplished throu gh en tries in the Config tabl e, Ice Build Setpoint ta ble, and the Ice Build
Time Schedule table. Figure 16 and Figure 17 show how to access each entry.
The Ice Build Time Sche dule defines the perio d during which ice b uild is active if the ice b uild
option is ENABLED. If t he Ice Build Time Schedul e overlaps other schedu les defining time, the n
the Ice Build Time Schedu le shall take priority. During the ice build perio d, the WATER/BRINE
CONTROL POINT is set to the ICE BUI LD SETPOINT for temperatur e cont rol. 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. Termi nation of ice build can result fro m the ENT ERING CHILLED WATER/BRI NE
IMPORTANT: The Ice Build control option is only available on machines with PSIO
