4. ECW TEMPERATURE and Remote Contacts — Termination of compressor operation shall
occur when ICE BUILD TERMINATION is set to BOTH (temperature and contacts) option
and the previously described conditions for ECW TEMPERATURE and remote contacts
have occurred.
Note: Overriding the CHILLER START/STOP, WATER/ BRINE CONTROL POINT, and
ACTIVE DEMAND LIMIT variables by CCN devices (with a priority less than 4) during
the ice build period is not possible. However, overriding can be accomplished with CCN
during two chiller lead/ lag.
Return to Non-Ice Build Operations
Upon termination of ice build, the machine shall return to normal temperature control and
start/stop schedule operation. If the CHILLER START/ STOP or WATER/BRINE CONTROL
POINT has been forced (with a priority less than 4), prior to entering ice build operation, then
chiller START/STOP and WATER/BRINE CONTROL POINT forces will be removed.
