Note: When IDUs support single parameter control, you may not select other parameters.
The actual operating parameters of the IDUs depend on the logic of the IDUs, which are
generally those of the last operation of the IDUs.
Example:
Only the power-on parameter is selected. The values of the unselected
parameters of IDUs, including the set mode, set temperature, set fan speed, and
swing angle, depend on the logic of the IDUs, which are generally those of the last
operation of the IDUs.
Note: If IDUs do not support single parameter control, you need to set all general control
parameters at the same time. If only some of the parameters are set, unset parameters may
be different from what is expected. (General control parameters of IDUs include "Set mode",
"Set temperature", "Set fan speed", "Cooling temperature in auto mode", "Heating temperature
in auto mode", "Swing left/right", and "Swing up/down".)
Example:
If only the "Set mode" is set to cool, "Set fan speed" is set to low fan speed, "cooling
temperature in auto mode" is set to 26°C, and "heating temperature in auto mode"
is set to 20°C, after the IDU receives the command, "Set temperature" may be the
temperature set upon last startup or a random temperature, such as 30°C, and
"Swing left/right" and "Swing up/down" may be auto swing or fixed swing angles.
Note: You must select a mode before you can change the set temperature.
Note: When a control command is sent, it takes a certain length of time for the centralized
controller to refresh the latest state of IDUs. The specific time depends on the number of
connected devices. (According to laboratory test data, when the connected devices are
8 refrigerant systems and 64 IDUs, the maximum polling cycle lasts for about 15 minutes. The
actual duration may vary.)
