Frequently Asked Questions
Does a controller reduce chemical consumption?
Only by dosing more accurately.
It produces no sanitiser of its own.
Manual dosing tends to overshoot and correct.
Continuous small corrections use less overall.
The saving comes from precision, not chemistry.
Water quality usually improves more than cost falls.
What does ORP actually measure?
How effectively the water is oxidising.
It is not a measure of sanitiser concentration.
The two diverge under changing conditions.
Rising pH suppresses ORP at unchanged chlorine.
That is why pH is corrected first.
A controller working in that order is correct.
How often do probes need calibrating?
More often than buyers expect.
Drift and fouling are continuous processes.
Service life runs to months rather than years.
An uncalibrated probe doses confidently and wrongly.
That is worse than not dosing at all.
Ask the interval before comparing purchase prices.
Why is a flow interlock essential?
It stops dosing when circulation stops.
Otherwise chemical enters a static pipe.
Concentrated dose then sits against fittings.
It reaches the pool as a slug when the pump restarts.
The interlock should be hardwired, not scheduled.
Confirm it during commissioning.
Is data logging necessary?
In commercial installations, usually yes.
Many regulators expect records of water quality.
Logging also shows whether dosing is stable.
Trends reveal a failing probe before a reading does.
Export format matters for record keeping.
Check what the local authority actually requires.
