More than just an ordinary heat pump management tool, PolyConnect communicates directly with the POLYTROPIC Technicenter and allows the secure remote management of heat pumps: supervision, preventive maintenance and ease of maintenance. SIMPLIFIED IMPLEMENTATION A WiFi box is installed as standard inside all our Inverter PACs (marketed from 2022), and easily accessible. From 2023 an option 4G is available. All you have to do is connect the heat pump to the customer's WiFi network by scanning the machine's QR code, entering the network's security code and pressing the button on the WiFi box to pair. Or with 4G option, connection is immediate. REMOTE MANAGEMENT A real preventive maintenance tool, the information is transmitted to our TechniCenter which can then anticipate any problems remotely, access the parameters and adjust, optimize or even update the heat pump. The Modbus connection allows access to all the heat pump parameters and modification in "direct mode". PROACTIVITY Thanks to the feedback of error codes, the TechniCenter 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 . EFFICIENCY PolyConnect is linked to the POLYTROPIC TechniCenter and allows our technicians to visualize the entire fleet of heat pumps as well as the status of each machine. In the event of an error code, they can access the device settings via their secure interface to resolve the fault. No need to send a technician to the installation to see what the problem is, to collect simple information or to adjust the devices. POLYCONNECT IS A SECURE, FREE AND ERGONOMIC APPLICATION. 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... In order to ensure a complete follow-up, all the data of the heat pumps connected to PolyConnect are stored for 5 years: • the history of all alarms • internal sensor temperature probes • the operating time of compressors, pumps, etc. • user settings PolyConnect was developed by our internal services and all our servers are based in France (GDPR law respected).
