The innovative mobile remote control with AI support for your Hargassner heating system. With Hargassner’s new app, you can easily and quickly control your heating system, make changes, and access information anytime, from anywhere. The app is particularly user-friendly and clearly designed. Information: You get a real-time overview of your entire heating system. The operating status of the boiler, buffer and hot water tank, heating circuits, pumps, and their temperatures are displayed. Fresh water stations are also integrated, as well as a function selector for combination systems. If a solar system is installed, the app also displays its information and the heat quantity meter. Detailed views provide information about temperatures and pump status. A graph shows the progression of various temperature trends. Brand new features include the integrated AI support assistant “Hargy” and support for an existing Hargassner heat pump with optional weather service integration. Adjustment: The app allows you to easily switch heating circuits on/off or lower them, change heating times, set heating temperatures, and activate holiday mode. It’s also possible to set key parameters for domestic hot water preparation. For the buffer storage or boiler, an additional “one-time charge” function is available. Notifications: The app immediately sends important information via push notification or email to your mobile device, so you always know the status of your heating system. These messages can also be sent to any number of other people. WEB VERSION: By switching to the WEB portal, you get even more extensive configuration options and additional information. This allows you to keep an eye on everything across devices – whether PC, notebook, smartphone, or tablet.
