Is it just the to shut off the water flow to the static tanks when they are full?

I have ro that fills a static 1000lt tank fitted with a same control that is used in toilet systems. For the cost of £10. Works a treat for me.

If using a plumbing float valve on a commercial RO system all you are doing is effectively blocking the product pipe when the tank is full. This does not stop the RO working but all the water will be forced out through the waste. The downsides to this are that you are still consuming large quantities of water which is still being treated by the pre-filters. Also blocking the product outlet whilst not fully opening the flush valve could, long term, degrade the membrane.

The advantage of the S2 controller is that when the tank is full it shuts off the whole water supply to the RO unit. It also shuts off the power supply to a 240v booster pump. Additional features of these units are twin TDS water monitoring (pre and post DI) and water temperature monitoring.

Alex, you've just saved me chewing Cassies ear, who in turn would've chewed yours!

Thanks!

Mines shuts all off, have device that shuts waste off when the pure water is shut off to,  no water waste. Pumps on pressure switch so that shuts down to.

Ian, I tried emailing you on the email in your profile but it bounced back?

Was asking whether the solenoid should go before or after booster, and what fittings are available for it.

Also, best fitting method for level switch, and any parts needed?

Cheers

Sorry I did not get back to you yesterday. email address should be ok and is ian.sheppard@springltd.co. I was having techie issues with the lap top yesterday basically it decided not to work. Thanks Alex.

Hi Ian,

There is no wiring diagram included in the instructions, please coud you let me know the corresponding wires? Don't want to make it go pop before I even use it!

Hi Concept


On the S2 there are the following wires:

A black and a grey wire which connect to the appropriate wires on the solenoid valve.
Two yellow wires which connect to either of the two wires from the float switch.
Plug the system into the mains with the 3-pin plug and plug your booster pump into the system's 3-pin socket.

You also then have 2x TDS probes which have John Guest 1/2" stem fittings on the end and these would need to connect onto a John Guest 1/2" T connector or similar which is in the direct line of your water processing.

I will also email you the full set of instructions which has a wiring diagram.

Thank you Alex.

Ian, been trying to contact Alex, but whoever can answer 1st...

On the FILL cycle, after the float valve kicks in and turns everything off, and some of the water is taken out, how long until the system powers up again?

Thanks

Here is the official reply from the manufacturers:

1st Thought is that the client has manually over ridden the auto fill cycle, has he pushed the FILL button and does the display show STOP ?

If he has he needs to push the FILL button again so FILL is displayed

To start filling the tank simply press the 'FILL'. This will
activate the pump and the solenoid valve, allowing water
to fill the tank, until the float switch detects that the tank
is full.
While the pump and solenoid valve are on and the tank
is filling, the display will flash the message FILL. Whilst
FILL is active the unit will keep filling every time the
level switch drops, hence maintaining the correct level.

You will find on the Solenoid page of the manual that I sent you this morning that it also contains instructions on this use. Basically If FILL is displayed then the tank should auto fill once the level switch falls and open the solenoid valve.
