Network Variables- Alphabetically
Network variables for the LCI-C Extension are listed alphabetically in Table 1 with
columns for chillers types.
Not all variables are available for every chiller. For example, the variables
nvoAirFlowPctC1 and nvoCondFans apply to other chiller models that use the LCI-C
extension.
