Parameter Description
by the master unit.
 When Requirement control is
set to Disable, the master unit
does not synchronize operating
data to slave units, and all the
cooling products operate based on
their own requirements, not
referring to the mode delivered by
the master unit.
Cascade If requirement control is enabled, you
can enable the cascade function to
start standby units if running units
cannot meet the cooling capacity
requirement.

L1/L2 linkage Reference temperature at which the
cooling stop cooling product stops cooling in the
ref. temp cooling mode in L1/L2 linkage.
L1/L2 linkage Reference temperature at which the
dehumid stop cooling product stops
ref. temp dehumidification in the
dehumidification mode in L1/L2
linkage.
L1/L2 linkage Duration within which the device is
cooling stop still cooling when the cooling stop
delay condition is met in L1/L2 linkage.
L1/L2 linkage Maximum temperature rise rate when
fastest temp the temperature rises rapidly caused
rise by sudden load power increase.

Configuration Principle
If the heat load of devices may
increase, it is recommended that you
enable the cascade function.
You are not recommended to change
the value.

Set this parameter based on the lowest
temperature allowed onsite. Normally
you are not recommended to change
the default value.
Set this parameter based on the lowest

Set this parameter based on the lowest
temperature allowed onsite. Normally
you are not recommended to change
the default value.
Set this parameter based on the
micro-module size and maximum load
power. The smaller the module and the
higher the load power, the greater the
temperature rise rate is.
