button on HMI screen, or remote emergency stop contact.
The Network Schedule should be configured if a CCN system is
being installed. When control mode is NETWORK, the chiller can
be started and stopped by the CHIL_S_S software point as written
by other equipment through the network command and network
schedule. The chiller can be shut down by EMSTOP software
point and remote emergency stop contact.
For more information about setting time schedules, see the 19XR
with PIC6 Controls Operation and Troubleshooting manual.
