Table 6-3 Description of control mode diagram
The colors in the circle are green, gray, and red. For details, see Table 6-4.
The measured supply air temperature value changes with the change of the compressor’s current control mode.
The humidity setting value changes and rotates clockwise between 30-150 polar coordinate angles according to
the range of humidity setting value. When the humidity setting is the minimum value, the value is 30 degrees in
the polar coordinate, when the humidity setting value is the maximum value, and the humidity setting value is
150 degrees in the polar coordinate.
Humidity control is the air supply humidity control by default, showing “supply”
