Description
Indicates whether to enable or disable the
requirement control function on the master unit.
● When Requirement control is set to Disable, the
master unit does not synchronize operating data
to slave units, and all the smart cooling products
in the group operate based on their own
requirements, not referring to the mode delivered
by the master unit.
● When Requirement control is set to Anti-
competitive running, the master unit
synchronizes operating data (the temperature and
humidity control type and set points of the master
unit) to the slave units, and all the smart cooling
products in the group refer to the mode delivered
by the master unit.
● When Requirement control is Indoor fan unified
control, all smart cooling product fans in the
group rotate at the same speed.
If this parameter is set to Enable, the smart cooling
product, which is not equipped with a differential
pressure sensor in the group, is logically controlled by
using the highest, smallest, and average values of the
data acquired by the differential pressure sensors
that have been installed.
When requirement control is enabled, you can enable
the cascade function to start standby units if running
units cannot meet the cooling requirement.
This function can be enabled only when at least one
smart cooling product in the teamwork group is
equipped with cold aisle T/H sensors. If this function
is enabled, the master unit in the teamwork group
collects the cold aisle temperature and humidity
values from all units equipped with cold aisle sensors,
and synchronizes the temperature and humidity
control type and setpoints to all slave units.
This function can be enabled only when at least one
smart cooling product in the group is equipped with
hot aisle T/H sensors. If this function is enabled, the
master unit in the teamwork group collects the hot
aisle temperature and humidity values from all units
equipped with hot aisle sensors, and synchronizes the
temperature and humidity control type and setpoints
to all slave units.
