Description
The module supports the four remote functions when it
connects to the NMS.
● Telemetry: measures the supply air temperature, return air
temperature, supply air humidity, return air humidity, and
working status of the unit.
● Teleadjust: adjusts the temperature, humidity, and alarm
threshold.
● Teleindication: generates alarms for the startup/shutdown,
overvoltage/undervoltage, high/low return air temperature,
high/low return air humidity, air filter normal/blocked, and
fan normal/faulty state.
● Telecontrol: controls startup/shutdown.
When multiple units work cooperatively, the controller
optimally distributes the heat load to reduce energy
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 units 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 unit in the network without a
master unit can automatically become the master unit to
continue teamwork control.
Users can remotely manage the operating status of one or
more units.
● A large number of fault alarm records can be stored. Alarms
can be managed by severity. A maximum of 500 historical
alarms can be stored for each severity. That is, a maximum
of 1500 historical alarms can be stored.
● The controller displays up to 30 days of temperature and
humidity in colored curves. O&M personnel can view the
operating status of the device onsite.
Access logs can be backtracked. Up to 1000 historical operation
logs recording login and setting can be stored.
