AI Intelligent Control

AI Full Inverter Technology

Built on operating data from more than 25,000 installed heat pumps, PHNIX AI Full Inverter Technology adjusts compressor frequency and expansion-valve control to match real-time demand more precisely. Dynamic-tariff adaptation and intelligent scheduling further reduce unnecessary operation, delivering more than 30% energy savings while maintaining stable indoor comfort.
AI Smart Defrosting

Conventional defrosting can interrupt warmth and consume energy even when it is not needed. GreenTherm Plus monitors ambient temperature, humidity and actual frost conditions to determine the right time to defrost. Fewer unnecessary defrost cycles mean more consistent winter comfort, lower energy consumption and reliable operation in freezing weather.
Built-In R290 Safety

GreenTherm Plus combines an integrated gas separator with a potted control board and optional high-precision R290 leak detection. The gas separator captures and vents gas and microbubbles from the water circuit, while the protected PCB helps resist moisture, insects and corrosion. Together, these safeguards support safer indoor heating integration and more dependable long-term operation.
Designed for Easier Installation & Service

An optimised water circuit reduces water resistance by up to 5 kPa, supporting smoother circulation and more efficient heat exchange. Convenient side access makes terminal wiring and PCB replacement easier, while the potted control board protects critical electronics against moisture, insects, corrosion and short circuits. This practical structure helps reduce installation complexity and simplify service throughout the product lifecycle.
Hybrid Energy Integration

Ready to work with photovoltaic systems, dynamic electricity tariffs and new or existing boilers.
