– Teleindication: startup/shutdown states, overvoltage/undervoltage, return
air overtemperature/undertemperature, return air overhumidity/
underhumidity, filter normal/blocked, and fan normal/faulty
– Telecontrol: smart cooling product startup/shutdown
Teamwork control: Up to 32 smart cooling products can be networked for
teamwork. When multiple smart cooling products work cooperatively, heat
load is optimally distributed to reduce power consumption and backup is
provided to improve reliability.
– When a smart cooling product in the group is faulty, the backup smart
cooling product starts to operate automatically to improve the reliability
of the smart cooling product system.
– Rotation: Each unit enters the active mode one by one periodically.
– Cascading: The number of operating smart cooling products varies
depending on the thermal load in the equipment room to meet
requirements promptly, eliminate hot spots, and save energy.
– Competition prevention: To save energy, a mechanism is adopted to
prevent the smart cooling products in the same equipment room
operating in opposite status (such as cooling and heating, or
humidification and dehumidification).
Remote management: You can monitor, manage, and upgrade one or more
smart cooling products using the remote management function provided by
Huawei.
At least 1500 historical alarms can be stored.
Access logs can be traced back. At least 1000 historical login and setting
records can be stored.
The display panel can display 30 days' temperature and humidity in colored
curves. O&M personnel can view the smart cooling product operating status
onsite.
A comprehensive power monitoring function is provided. Faults such as power
open phase, overvoltage, undervoltage, high frequency, and low frequency are
diagnosed and appropriate alarms are reported and recorded. Automatic
protection, recovery, and restart are also provided.
The display panel provides a touchscreen with a user-friendly interface.
The display panel controls the indoor temperature precisely and responds
quickly.
The display panel is protected by a multi-level password protection
mechanism, avoiding misoperations.
The password is verified each time the system is powered on or off to ensure
system operation security.
The display panel provides multiple protection functions, such as chilled water
valve exception feedback, abnormal power-off self-recovery, and water
leakage detection, ensuring system reliability.
The display panel displays the operating status and duration of the smart
cooling product components in real time.
The professional fault diagnosis system automatically displays fault
information, which facilitates maintenance.
