NOTES
1. Automatic means that when the controller
stops, the vent valve is opened with a delay de-
fined by window n. 126; when the controller
starts, the vent valve is immediately closed.
2. On command means that the vent valve is
opened or closed by means of window n. 122.
3. These commands remove the pump motor
supply for a short time. If they are used con-
tinuously, they can cause the pump stopping.
