operating.
Operation display: You can set parameters for the device and query its status on the
7-inch true-color touchscreen.
Three remote functions:
− Telemetry: supply air temperature, return air temperature, supply air humidity,
return air humidity, and working status of the unit
− Teleindication: startup/shutdown status, overvoltage/undervoltage,
overcurrent/undercurrent, return air overtemperature/undertemperature, return air
overhumidity/underhumidity, air filter normal/blocked, and fan normal/fault
− Telecontrol: startup/shutdown
Teamwork control: Up to 32 devices can be networked for teamwork. When multiple
devices work collaboratively, heat load is optimally allocated to reduce power
consumption and backup is provided to improve reliability.
− Backup: automatic switchover. When a single device in the group is faulty, the
backup device starts to operate automatically to improve the reliability of the
system.
− Rotation: Each device enters the active mode one by one periodically.
