Setting T/H Sensor Parameters
Prerequisites
- If T/H sensors outside cabinets have been deployed in the aisle, enable the sensors. Otherwise, skip 2.
- This section describes how to enable Cold aisle sensor 1.
Procedure
- On the home screen, choose . The screen shown in Figure 6-10 is displayed.
- Set Cold aisle sensor 1 to Enable.
- Set temperature and humidity parameters.
Parameter
Description
Cold aisle sensor
Enables or disables a sensor.
Hot aisle sensor
Enables or disables a sensor.
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: 26–35°C recommended
- Supply air: 18–24°C recommended
- Cold aisle: 18–24°C recommended
- Hot aisle: 26–35°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.
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.
