(Optional) Connecting T/H Sensors Outside the Cabinet
8.2
The T/H sensors outside the cabinet are used to detect the temperature and humidity of remote
points. The installation position can be determined based on the site requirements. It is
recommended that the sensors be deployed near heat sources, or near places that lack cooling
capacity. Place the T/H sensors outside the cabinet near the cabinet. The sensor cannot face the
air outlet of the device.
1. Connect the IN port on the T/H sensor outside the cabinet to the RS485/12V port on the
main control board.
2. Connect the OUT port on the T/H sensor outside the cabinet to the IN port on the next
T/H sensor outside the cabinet in series.
3. Set DIP switches of the T/H sensors.
After the addresses are set, power on the device, choose Settings > System Settings > T/H
Sensor on the home screen, and set the sensors in the aisles corresponding to the addresses to
Enable. Otherwise, the sensors will not work.
