Description
Forced rotation specifies
whether to enable a forcible
rotation on the group before
the specified rotation time.
After a forced rotation, the
accumulated time is
recalculated.
Enable or disable the
requirement control for the
master device.
 When the requirement
control is Enable, the
master device synchronizes
data (the temperature and
humidity control type and
set points of the master
device) to the slave device,
and all the smart cooling
products in the group refer
to the mode delivered by
the master device.

When the requirement
control is Disable, the
master device does not
synchronize data to the
slave device, and all the
smart cooling products
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 smart cooling
products if the active one
cannot meet the refrigerating
requirements.
Proportion coefficient in
L1/L2 linkage PID control.
Integration coefficient in
L1/L2 linkage PID control.
Differential coefficient in
L1/L2 linkage PID control.

Configuration Principle
This item is set to No by
default. If forced rotation is
required, the function is set
to Yes.
The requirement control
function 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 to the
device increases, the
cascade function is
recommended.
You are not recommended
