Set the Balance of water and electricity consumption parameter based on the site
requirements. You can select Power saving mode, Normal water saving mode, Extreme
water saving mode, or Customized mode.
After Balance of water and electricity consumption is set, the priorities of the working
modes are as follows:
Power saving mode: dry mode → wet mode → hybrid mode (wet mode + auxiliary cooling
mode)
Normal water saving mode: dry mode → wet mode → hybrid mode (dry mode + auxiliary
cooling mode)
Extreme water saving mode: dry mode → hybrid mode (dry mode + auxiliary cooling mode)
→ wet mode
Customized mode: The wet mode priority is determined based on the user-defined
temperature.
The working mode is automatically determined by the unit based on the cooling
requirement. The cooling requirement is related to the load rate and return air temperature
and humidity of the equipment room as well as the outdoor intake air temperature and
humidity. The requirement is calculated by the unit based on the preset temperature. If the
current working mode cannot meet the cooling requirement of the equipment room, the
lower-level working mode is automatically enabled to supplement the cooling capacity.
