FULL INVERTER TECHNOLOGY

Unlike a traditional heat pump with a single-speed compressor which by switching on and off periodically to adjust the performance of the heating & cooling, a full inverter heat pump uses a variable-speed compressor that can automatically adjust the output needed at the lowest consumption of power and maintain the best temperature at different climatic conditions. When the heating demand is high, the inverter compressor and the fan motor will start running at a high speed, inversely, they will run at a low speed.

BROAD CLIMATE SUITABILITY

The unit can adapt to wide climate. Under lab test, it keeps stable operation in -15℃ to 53℃. This character makes the unit suitable for markets all over the world.

INTELLIGENT CONTROL SYSTEM WITH WIFI AND BMS FUNCTION

The controller features a touch screen for effortless operation and clear settings display, with WIFI and BMS function, its intelligent control technology ensures quick, accurate responses, allowing precise temperature management. The optional Boost function enhances performance with rapid heating when needed.

MODBUS RS485

With Modbus RS485 option, can offer external connect for special requirement.
