Solution - Pools

Pool equipment is controlled from the PIERRE system through the same outputs and inputs used elsewhere: relays for pumps and valves, dimmable or switched outputs for lighting, and temperature sensors for the water.

What Can Be Controlled

• Water circulation — valves for massage jets, waterfalls and other circuits, each on its own output.
• Water temperature — a temperature sensor in the circulation line provides the reading, and heating or cooling is switched from it.
• Lighting — underwater lighting and the surrounding area, switched or dimmed, and usable in scenarios.
• Covers and valves — motorised covers and actuated valves driven as outputs, manually or on a schedule.
• Pumps and filtration — run on a schedule, or bound to a condition.

Automation

• Filtration on a daily schedule, with the runtime set per season.
• Heating held to a target water temperature, using the measured value from the pool sensor.
• Lighting bound to sunset or to a scenario.

Technical Notes

• Pumps and heaters are switched through contactors sized for their load; the controller relay drives the contactor coil, not the motor.
• Pool areas have their own electrical zone requirements. Follow the local regulation for the installation zone, earthing and equipotential bonding — these are not decided by the control system.
• Use a sensor rated for continuous contact with pool water and mount it in the circulation pipe, not in the basin.
• Keep manual isolation available for every pump and heater, so the equipment can be serviced with the control system running.
