Filling
Connect the pump controller following this diagram. Use only wire from the middle
gland. NOTE: only fit the fuse once all connections are made.
To start filling the tank simply press the ‘F’ (Fill) button briefly. This will activate the RO
inlet solenoid valve, allowing water to fill the tank, until the float switch detects that the
tank is full.
When fill is started the system will open the
Autoflush valve for 5 mins (in every hour) to
clean RO.
The Autoflush valve will then close when
flushing has finished and controller will
continue to fill via the RO inlet valve.
After flushing the booster pump will turn
on if ‘boost on flush’ is ‘off’.
System
Full
When the tank water level rises sufficiently
to activate the level switch, filling is stopped.
All valves are closed.
To manually stop the tank filling, (if ‘On
Demand’ is ‘Off’) press the ‘F’ (Fill) button
again breifly. The display will remove the
‘Fill’ message.
NOTE 1: The solenoid valve will be turned off if the unit detects a loss of mains
water pressure (below 10 PSI).

TDS Wiring
S3
For the TDS probes in John Guest 1/2” equal tee pieces (not supplied) as shown on
the diagram.
We recommend RO TDS probe to be fitted after the RO (reverse osmosis) filter. You can
then check the RO is working correctly. If you see these values rising over time it could
indicate a problem with the RO.
We recommend DI TDS probe be fitted after the DI (de-ionising) vessels. You can then
check DI vessels are working (and that the resin is not depleted).
For good cleaning a TDS value below 5ppm after the DI is recommended.
The TDS function provides an indication of the water purity. The TDS values displayed
are in ppm (parts per million). The TDS meter has a max reading of 50ppm.
To monitor the current TDS reading press enter repeatedly until it displays the TDS screen.

Probe
Take care when handling TDS probes. Do not damage gold plated contacts
as this will affect TDS accuracy.
Ensure gold plated contacts are clean before use. Clean with ISOPROPANOL
alcohol (IPA) and a soft cloth.
Dirty contacts will affect TDS accuracy, clean with IPA if readings appear to
deviate over time.
