*1. The names of port "a" through "h" are corresponding to port 1 through 8.
*2. Valve opening is controlled with 0, 800,1600 pulses. In the Maintenance Tool, "0" indicates 0 pulse, "1" indicates 1600
pulses, and "2" indicates 800 pulses.
*3. For the degree of valve opening, "0" indicates fully open and "1600" indicates fully closed.
