Network Variable and Configuration Property Definitions
This network variable provides the rate of water flow in the evaporator.
• Default: 0xFFFF = 65535 L/s
• Invalid value: 0xFFFF = 65535 L/s
nvoEvapWtrFlow
Evaporator water flow status, SNVT_switch
This network variable indicates that there is water flowing through the evaporator.
nvoEvapWtrPump
Evaporator water pump output, SNVT_switch
This network variable indicates a request from the chiller to turn on the evaporator water
pump.
nvoFileDirectory
File directory, SNVT_address
This network variable points to a file directory containing descriptors for the files in the
device. It is used because the LCI-C implements configuration properties as configuration
parameter files accessed by network management read/write messages.
