Hi All, Bit long but hoping covered all.
Firstly cheers for all the research and useful info found on here - not really used Forum before but the time has come to reach out as having minor issue that bugged me for a while
tried all sorts of "When" / If / OSC Statements but not managed any to get what i thought was a simple fix "as yet"
Basically have 2 x float switches in my RODI Tank Programmed to the Outlet called RODIPUMP Using simple enough program to switch off pump when high and not switch back on until lower switch open.
along with above i have a pressure switch on a ball valve connected direct to the pump as a backup) if that fails i have a straight to waste pipe at the top of tank as a further backup...CANT HAVE TO MANY BACKUPS...
Outlet for (RODIPUMP)
Fallback OFF
If Sw1 OPEN Then ON
If Sw2 CLOSED Then OFF
Works a treat thanks to these forums
Problem - have a flush valve on my RODI Unit that manually switch, have both an Auto flush solenoid and a normal on / off solenoid. not a fan of the auto flush so wanted to set my own auto flush and duration times. (Example only) = on for 2 mins then off for 30 mins. this to cycle through while the "RODIPUMP" ON (reset to a default timer state once pump off)
simplest one set out below, using the OSC Function i found that on / off times simply start / stop as per whenever the pump switched off. it will just pickup the remaining time before it was switched off. not ideal when would like to flush membranes before making water each time the RODIPUMP turns on.
below program is connected to separate outlet called - Flush
Flush (outlet Name)
Fallback OFF
If Output RODIPUMP = ON Then ON
OSC 000:00/000:05/000:20
If Output RODIPUMP = OFF Then OFF
once Pump on it needs a 2 min on time / 30 min off time (this to carry on until higher switch turns pump off. whenever the pump comes back on it needs to default back to (2 mins on then off 30 mins) and so on..
THANKS FOR READING AND IF ANYONE CAN HELP AT ALL I WOULD BE VERY GRATEFUL
For anyone interested added image of the thing that been taking up my time for the last couple years....
