12. Changing Over the Operation Modes
The valve has three operation modes; “control mode,” “fully closed mode” and “fully
opened mode.” When the equipment is shipped, it is in the control mode. It can be forced
to the “fully closed mode” (valve fully closed) or “fully opened mode” (valve fully opened).
Each time the [RUN] key is pressed, the mode is changed over between “control” and
“fully closed” alternately as shown below. To change the control mode to the fully opened
mode, press and hold the [RUN] key for 2 seconds or longer.
