Schedule is UNOCCUP I ED. The contacts are used to stop the ICE BUILD mode when the
Ice Build Time Sched ule is OCCUPIED.
4. ECW TEMPERATURE and Remote Contacts — Termination of compressor operation shall
occur when ICE BUILD TERM I NATION is set to BOTH (te m per a ture and contacts) opt ion
and the previously described conditions for ECW TEMPERATURE and remote contacts
have occurred.
Note: Overriding the CHILLER S T ART/STOP, WATER/ BRI NE CONTROL POINT, and
ACTIVE DEMAND LIMIT variables by CCN devices (with a priority less than 4) during
the ice build period is not pos s i ble. However, over r idi ng can be accomplish ed wi th CCN
during two chiller lead / lag.
Return to Non-Ice Build Operations
Upon termination of ice bu ild, the machine shall r et urn to normal temper at ure control and
start/stop schedul e ope ration. If the CHILLE R S T ART/ STOP or WATER/BR IN E CONTROL
POINT has been forced (w it h a priority less than 4), pr io r to entering ice build op eration, then
