Setting T/H Sensor Parameters

Procedure

1. On the home screen, choose Settings > System Settings > T/H Sensor.
   Figure 5-5 Setting humidity and temperature
   

2. Set Return air sensor 2 to Enable.
3. Set temperature and humidity parameters.

   You are advised not to modify the parameters that are not listed here.

   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.
   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: The value ranges from 18°C to 45°C. Supply air: The value ranges from 15°C to 35°C. Cold aisle: The value ranges from 15°C to 35°C. Hot aisle: The value ranges from 18°C to 45°C.
   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.
