Description
synchronize data to the
slave device, and all the
air conditioners operate
based on their own
requirements, not
referring to the mode
delivered by the master
device.
After the requirement control
is enabled, you can configure
Cascade. The cascade
function starts standby
precision air conditioners if
the active one cannot meet
the refrigerating
requirements.
Indicates whether to enable
chiller linkage. If this
function is enabled, all smart
module air conditioners
adjust the chiller control
temperature based on
workloads to increase the
system energy efficiency.
Indicates the chiller water
temperature tolerance (water
supply temperature condition
to be met by a precision air
conditioner after the chiller
linkage function is enabled,
that is, the difference between
the chiller outlet water
temperature and the inlet
water temperature of the
precision air conditioner must
be within the configured
range) after the chiller
linkage function is enabled.
The value range is 0–5° C.
Indicates the time needed by
the chiller to stabilize the
water supply temperature at
the set point after the chiller
linkage function is enabled.
The value range is 0–7200s.

Configuration Principle
If the heat load to the device
increases, the cascade
function is recommended.
Determine whether to enable
this function based on the
onsite heat dissipation
requirements and whether
the Huawei NetEco system is
used.
Set the parameter based on
the water temperature
precision requirement for the
chiller and the pipe length
between the chiller and an
air conditioner.
Set the parameter to the time
after which the difference
between the inlet water
temperature inside a smart
module and the chiller outlet
water temperature is within
the range set in the A/C
supply water temp diff
parameter.
