PROACTIVITY Thanks to the feedback of error codes, the professional can remotely trigger an appropriate after-sales service procedure immediately, even before the user of the pool notices a possible problem or its consequences. EXPERT TIPS The TechniCenter is at your disposal for advice on the rational management of your pool fleet and possible energy savings .

It allows remote control of the heat pump via a smartphone or tablet thanks to an intuitive interface: status of the machine, water temperatures, outside temperature, operation of the filtration pump, heating setpoint temperature, choice of operating mode, alerts, programming of operating ranges...
