Function Description
Four remote
functions
● 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
lter normal/blocked, and
fan normal/faulty state.
● Telecontrol: controls startup/shutdown.
Teamwork 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.
Remote
management
Users can remotely manage the operating status of one or
more units.
Storage ● 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.
Log
backtracking
Access logs can be traced back. Up to 1000 historical operation
logs recording login and setting can be stored.
Power
management
Supports alarm reporting, fault diagnosis, and alarm recording
for reverse phase, open phase, overvoltage, undervoltage, high
frequency, and low frequency; provides functions such as
automatic protection, recovery, and restart.
