Remote monitoring, anytime, anywhere.

Leveraging the power of IoT Technology, technical and expert teams gain remote access to the unit’s operations for in-depth analysis and troubleshooting. In the event of an error or malfunction, experts remotely examine various inputs and parameters, enabling them to adjust and devise a protocol for a rapid solution, restoring the unit’s optimal functionality and ensuring the customer’s satisfaction and warmth.

Unlock the advanced capabilities of Tongyi’s IoT feature, designed exclusively for technical experts. Tongyi’s IoT feature allows experts to monitor, adjust, and anticipate potential unit errors and upcoming malfunctions. Experience a solid and secure communication between the heat pump unit and diverse remote service centers via a 4G connection integrated within the unit’s system. Upgrade your customer experience as over 90% of unit errors are effectively addressed through this innovative feature. 

This unique capability is not intended for the end-user, as they already have an embedded Wi-Fi connection to control and manage the unit’s primary functions, such as consumption data, and basic temperature-adjust operations. The 4G connection designed for technical teams serves a distinct purpose from the one intended for end-users. It proves invaluable in situations where electricity and Wi-Fi are unavailable, allowing for easy connectivity to remotely diagnose and repair issues with the unit at any time, anywhere. 

Also Tongyi Heat Pumps are equipped with OTA (over-the-air) technology, the unit’s software could be remotely updated via internet connection in case of any errors. Furthermore, both distributors, installers, and end-users have the capability to remotely update the software to the latest version, filled with advanced features and enhanced functionality.
