Parameter
Description
Temperature and
humidity control type
When the application scenario is non-aisle
containment, you are advised to choose Return air.
Choose Cold aisle if cold aisle T/H sensors are
installed. Hot aisle is not recommended.
Temperature control
mode
The temperature inside the equipment room or aisle is
controlled based on the average value, maximum
value, or minimum value collected by multiple sensors.
Humidity alarm mode Set this parameter as required.
Temperature setpoint
After the temperature and humidity control type and
the temperature value under this type are set, the
device performs regulation based on the settings.
● Return air: 18–45°C recommended
● Supply air: 15–35°C recommended
● Cold aisle: 15–35°C recommended
● Hot aisle: 18–45°C recommended
Humidity setpoint
After the temperature and humidity control type and
the humidity value under this type are set, the device
performs regulation based on the settings.
40%–60% is recommended.
Cold aisle sensor
Enables or disables a sensor.
Hot aisle sensor
Enables or disables a sensor.
The relationship between the temperature setpoint and the humidity setpoint is as
follows: Under the condition that the absolute humidity range is [0.0026, 0.0141]
for the default temperature setpoint 23°C and relative humidity range [15% RH,
80% RH], ensure that the absolute humidity range is [0.0026, 0.0141] when you
set the temperature setpoint and humidity setpoint.
