Description
Each device has an independent control system, LCD, and T/H
sensor to ensure its normal and high-precision operation.
Users can set parameters and query status on the 7-inch true-
color touchscreen.
● Telemetry: supply air temperature, return air temperature,
supply air humidity, return air humidity, and working status
of the unit
● Teleadjust: temperature, humidity, and alarm threshold
● Teleindication: startup/shutdown states, overvoltage/
overcurrent, undervoltage/undercurrent, return air
overtemperature/undertemperature, return air overhumidity/
underhumidity, filter normal/blocked, and fan normal/faulty
● Telecontrol: startup/shutdown
When multiple units work cooperatively, the controller
optimally distributes the heat load to reduce power
consumption and provides backup to improve reliability.
● Backup: When a unit in the group is faulty, the backup unit
starts to operate automatically, improving system reliability.
● Rotation: Each unit enters the active mode one by one
periodically.
● On-demand operation: The number of operating units varies
depending on the thermal load power in the data center to
meet requirements promptly, eliminate hot spots, and save
energy.
● Anti-competitive running: A mechanism is adopted to
prevent multiple devices in the same equipment room
operating in opposite status to save energy.
● Independent teamwork control: If a communications cable in
the teamwork network is disconnected, two teamwork
networks are formed. A device in the network without a
master unit can automatically become the master unit to
continue teamwork control.
