The Bayrol PoolRelax® System is a fully automatic dosing and water management solution designed for swimming pools and spas. It continuously monitors and precisely controls pH and disinfectant levels, helping to maintain consistently clean, safe, and comfortable water with minimal manual intervention.

Using advanced high-precision testing technology, PoolRelax automatically doses your chosen disinfectant, chlorine, bromine, or active oxygen (additional components may be required for non-chlorine systems). By testing and adjusting in real time, the system prevents unwanted chemical spikes and keeps water chemistry at optimal levels, reducing chemical waste and protecting pool equipment.

Beyond water treatment, PoolRelax also functions as a central pool control system. With up to four integrated switching outputs, it can operate additional pool features such as lighting, waterfalls, or heat pumps. This functionality can be expanded further with the optional web module.

For added convenience, the optional web module allows remote operation via Wi-Fi, enabling you to monitor and manage your pool system from a smartphone or tablet anywhere in the house.
