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.
When requirement control is enabled, you can
enable the cascade function to start standby units if
running units cannot meet the cooling capacity
requirement.
When this parameter is enabled, the smart cooling
product, which is not equipped with the differential
pressure sensor in the group, is logically controlled
by using the acquired value of the differential
pressure sensor.
This function can be enabled only when at least one
smart cooling product in the 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 values to all units
after logical calculation.
After this function is enabled, the master unit
synchronizes the temperature and humidity control
type and setpoints to all slave units.
