Guardian Pool Automatic Controller

Guardian Pool combines conventional control and dosing elements with digital value control and records data to analyse possible faults. The built-in 4 MB data logger stores up to 16,000 records; data is downloaded via USB and viewed in graphs, and firmware is updated via USB. Thanks to the Wi-Fi module, it can be controlled from a mobile device, tablet or PC.

The chlorine sensor gives stable readings with up to 500 ppm isocyanuric acid in pools using sodium hypochlorite, dichlor, trichlor or salt chlorine; electrodes for bromine, peroxide, peracetic acid and ozone can also be used. It has 230 V / 6 A control relays for pH and free chlorine, an ORP relay, an additional relay that can be linked to total or combined chlorine, 2 configurable volt-free alarm relays and a 4–20 mA output for each parameter. Sensor inputs are galvanically isolated, and an LED-lit electrode holder indicates faults.
