To allow P/MV switching of water sources on sensor inputs, each station will need to be enabled for both P/MV outputs. When the sensor is triggered (open or closed), the P/MV that is not in use will be set to "Close P/MV." Depending on the status of the sensor, only one P/MV will be active as the affected sensor input will disable the opposite P/MV (water source).
There are two points of connection available: Potable water and non-potable water in a storage tank or pond. Each has its own Master Valve. A FLOAT SWITCH (closed sensor used in this example) is installed to monitor the non-potable level. All stations are set in STATION SETUP to call for both Master Valves.

To switch between P/MVs, two conditional responses (statements) must be created. Programming the P/MV OUTPUTS, FLOW ZONES (if you are using a flow sensor), and the SENSOR (e.g; float switch) should be completed prior to programming these statements.
Please view the setup instructions in each of the support sections listed below:
The COMPLETED STATEMENT will result in P/MV 1 remaining open for non-potable water supply and P/MV 2 remaining closed.
The COMPLETED STATEMENT will result i P/MV 1 closing when the float switch opens and PM/V 2 opening for the potable water supply.
