Description
Indicates whether to allow the
smart cooling products to work as
the standby device in turn,
maximizing their service life.
Number of days for rotation (1–
30).
24 time points in a day: (0-23).
Indicates whether to enable
forced rotation before the
specified rotation time. After a
forced rotation, the rotation
period starts again.
Indicated 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 requirement control is enabled,
you can enable the cascade
function to start standby units if
running units cannot meet the
cooling capacity requirement.

6 Power-On Commissioning
Setting Rule
It is recommended that the
function be enabled when
the load power is even.
The default value is 7.
The default value is 0.
Set this parameter to Yes if
forced rotation is required.
In normal cases, retain the
default value No.
Anti-competitive running
is recommended for the
following scenario: In one
teamwork, the temperature
and humidity control type
and temperature and
humidity set point of units
are the same, and device
heat loads are distributed
evenly.
If the heat load of devices
increases, it is
recommended that you
enable the cascade
function.
