4 TMV-Vd255W/N1-C1 AI Energy saving Our system achieves an additional 20% energy
savings on top of full DC inverter technology.
This is accomplished via AI-driven adaptive
control with 0.1Hz precision for optimal lowpower efficiency.
Cooling steadily from -10 to 56 °C which meet various of working conditions and scenarios.
High VEEC Value
The Victorian Energy Upgrades (VEU) program
assists households and businesses to reduce
their energy bills and greenhouse gas emissions
by providing financial incentives to install
energy efficient equipment and appliances.
The VEEC value up to 106, higher than Midea
105, users can receive more subsidies from the
Australian government.

enhance stability.
*After self-clean mode , the outdoor fan will reverse automatically
According to the set temperature, the system will control the refrigerant flow precisely and adjust the evaporating/
condensing temperature automatically through the EEV and temperature sensor, which decrease the temperature
fluctuation to make sure the room temperature more confortable.
