Frequently Asked Questions
What does a pool controller change on its own?
Nothing physical.
It holds schedules, setpoints and permissions.
It decides when other equipment may run.
Water moves only when an actuator turns.
A controller without actuators is a timer.
Buy the layer that is missing.
Why are valve actuators needed at all?
They route water between destinations.
Pool, spa, solar array and waste each need a path.
A controller can only start and stop without them.
Turning valves by hand defeats a schedule.
Spa changeover is the most common reason to fit them.
Torque and valve body have to match.
How do automation sensors differ from pool alarms?
They watch the plant, not the people.
Automation sensors report water and air temperature and flow.
They exist so the controller can decide.
Safety alarms detect a person entering the water.
Those answer a supervision obligation instead.
Buying one does not cover the other.
Will a controller work with equipment already installed?
Sometimes, and it has to be checked first.
Heaters and sanitisers use manufacturer protocols.
Cross-brand support is uneven and often partial.
A relay can switch plant without reading it.
That loses status feedback and diagnostics.
Confirm compatibility before ordering anything.
What happens if the controller fails?
That depends on how it was specified.
Some systems fail with the pump stopped.
Others hold the last state until reset.
A manual bypass keeps filtration running.
Losing circulation for days spoils the water.
Ask what happens on power and network loss.
Local panel or phone app?
It follows who operates the pool.
Rotating commercial staff need a fixed local interface.
Locked setpoints prevent well-meaning adjustment.
A private pool is better served by a phone.
Remote access also needs a network that stays up.
Specify for the operator rather than the owner.
Can automation be added in stages?
Yes, and usually it should be.
Start with the controller and the pump.
Add actuators once a second destination exists.
Sensors follow the functions that need them.
Leave conduit and spare ports at first fix.
Staging costs less than replacing a closed system.
