(Optional) Team Setting
When supporting the group control function, the operator
must make the relevant group control setting after the
chiller is powered on for the first time and runs normally,
otherwise the group control function will not be realized,
and the chiller will return to the independent operation
control mode.
Group control can improve the efficiency of
chillers and avoid the competition between
chillers by cascading multiple chillers.
Group control function is an optional function.
When the group control function is not provided,
the values of the parameters in the Team Setting
interface are displayed as "****", as shown in
Figure 4-15.
