The 7-inch display panel with the true-color touchscreen allows you to set parameters for
the air conditioner and query its status.
The air conditioner has the following three remote functions.
−
Telemetry: supply air temperature, return air temperature, supply air humidity,
return air humidity, and working status of the air conditioner
−
Teleindication: startup/shutdown, overvoltage/overcurrent,
undervoltage/undercurrent, return air overtemperature/undertemperature, return air
overhumidity/underhumidity, filter normal/blocked, and fan normal/faulty
−
Teleadjust: air conditioner startup/shutdown
When multiple air conditioners work cooperatively, the controller optimally distributes
the heat load to reduce power consumption and provides backup to improve reliability.
−
When an air conditioner in the group is faulty, the backup air conditioner starts to
operate automatically to improve the reliability of the air conditioning system.
−
Each air conditioner enters the active mode one by one periodically.
−
The number of operating air conditioners varies depending on the thermal load in
the equipment room to meet requirements promptly, eliminate hot spots, and save
energy.
−
A mechanism is adopted to prevent the air conditioners in the same equipment room
operating in opposite status (such as cooling and heating, or humidification and
dehumidification), in order to save energy.
You can monitor, manage, and upgrade one or more air conditioners using the remote
management software provided by Huawei.
At least 500 historical alarms can be stored.
Access logs can be traced back. At least 200 historical login and setting records can be
stored.
The controller can display 30 days' temperature and humidity in colored curves and 30
days' differential pressure of supply air and return air (differential pressure control
function required) in colored curves. O&M personnel can view the air conditioner
operating status onsite.
A comprehensive power monitoring function is provided. Faults such as power reverse
phase, 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 operating status and alarms of the outdoor unit are monitored using the touchscreen
controller on the indoor unit. Audible and visual alarms are supported and alarms can be
uploaded to the upstream element management system (EMS) for centralized
management.
Alarms about the condensate pump are monitored using the touchscreen controller on the
indoor unit. Audible and visual alarms are supported and alarms can be uploaded to the
upstream EMS for centralized management, which helps locate faults accurately and
improve the drainage reliability.
Features
The controller provides a touchscreen with a user-friendly interface.
The controller controls the indoor temperature precisely and responds quickly.
The controller is protected by a multi-level password protection mechanism, avoiding
misoperations.
