Single unit control: Each device has an independent control system, LCD, and
temperature and humidity (T/H) sensor to ensure its normal operating and
high-precision 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.
