Remote monitoring, anytime, anywhere.

Harnessing the power of heat pump and IoT (Internet of Things) technology, Tongyi’s advanced system enables technical experts to remotely access and analyze unit operations. In case of an error or malfunction, specialists can examine key inputs and parameters, make real-time adjustments, and implement a rapid solution—restoring optimal performance while ensuring customer comfort and satisfaction.

Unlock the full potential of Tongyi’s IoT-enabled heat pumps, designed specifically for technical professionals. This smart feature allows experts to monitor, adjust, and predict potential issues before they escalate. Thanks to a secure 4G connection, the heat pump seamlessly communicates with remote service centers, ensuring fast and reliable diagnostics. With over 90% of unit errors resolved remotely, this innovation significantly enhances customer experience and system reliability.

This unique capability is designed specifically for technical teams, not end-users. While end-users can control and manage the unit’s basic functions, such as consumption data and temperature adjustments, through the built-in Wi-Fi connection, the 4G connection serves a different purpose. It is invaluable in situations where electricity or Wi-Fi are unavailable, allowing technicians to remotely diagnose and repair issues from anywhere, at any time.

In addition, Tongyi Heat Pumps are equipped with OTA (over-the-air) technology, enabling the unit’s software to be remotely updated over the internet in case of errors. This feature also allows distributors, installers, and end-users to update the software to the latest version, unlocking advanced features and improving functionality.
