Here is the function block for PumpAndValve. This controls a pump and the associated valve. It will start the pump and open (in our case, a 3-way valve) to supply water to both tanks. It also has the ability to override both pump and valve to off or on, and it returns statuses for auto off or on, or manual off or on. The valve also returns if it is exercising. Furthermore, you can set the exercise time and interval for the pump. And you can enable stirring. When stirring, the valve is closed while the pump is on.
