When are the lights in the PC Software displayed as dark- or light-green?
The lights on the buttons, displayed in the "operating mode" tab of the PC Software display the actual status of the valve, as soon as connected to the control via USB, BUS or Internet.
The light is light-green, whenever the valve is open, seen in filtration-direction of the water, e.g.
- the drain valves V2 and V4 are light green during a Forward Flush, since then they are opened for water flowing from the inside of the unit to drain.
- the feed valves V1 and V3 are light green during filtration, since they then allow water to reach into the unit to be filtered.
- the filtrate valve is light green during filtration as well, letting water pass on to outside of the unit.
Accordingly, when displayed as dark-green, the valves have opposite functionality.
Depending whether the valve is normally open or normally closed, the valves is powered or not (does not equal any color generally)
