The icon gives access to the operating mode of the blower
The blower has 4 different operating modes:
1. The blower runs at a fixed speed.
2. The blower delivers a fixed static pressure or vacuum. The pressure is
measured with a pressure transducer connected to the blower control.
3. The blower delivers a fixed air speed. The air speed is measured with a
pressure transducer connected to the blower control.
4. The blower delivers a fixed air velocity. The air velocity is calculated
by checking the air flow as in point 3. In this operating mode, the pipe
diameter must be specified to calculate the air velocity.
