Features:
- Five basic Modes
  Unique five-mode operation is a breakthrough in traditional heat recovery technology where heating and water-heating cannot be achieved at the same time.
- Wide range of operation condition
  Outdoor operation temperature range is improved to -5°C ~ 50°C in cooling and -15°C~24°C in heating.
- Auto heat recovery in cooling
  When the indoor units are set in cooling mode, the heat which should be discharged into the environment is transferred to hot water. While you are enjoying the coolness brought by the air conditioner in summer, you can also enjoy free hot water. Meanwhile, the condensation effect of water tank is better than air-cooled outdoor unit. System high pressure is reduced and energy consumption is reduced by 10%.
- Air source heat pump technology
  Heat Pumps take thermal energy from the outside air. In order to take energy from the air the heat pump needs a bit of energy to startwith:GMV5 home requires only 1kW of electricity to pump over 4kW of heat into your home. In other words, extracting heat from air sources requires just 1kW of electrical input in order to generate over 4kW of heating output, more than 80% of the heat produced by GMV5 Home comes from the outside air and is free of charge.
- Heat recovery technology
  Thanks to the perfect technology of heat Recovery, during cooling operation, the condensing heat is recovered and reused to generate hot water for domestic use, which is free of charge.
- All DC inverter technology
  All DC inverter compressor and high-performance high pressure chamber are adopted to reduce loss of overheat and improve compression efficiency from direct intake. Compared with low pressure chamber, the compression efficiency is improved, High-efficient permasyn motor is adopted to provide better performance than traditional DC inverter compressor.
- 3D Heat Supply technology
  “Air conditioner+floor heating” in the same room can be turned on simultaneous.(Note: This function is available when these two modes are turned on just a few rooms.)
- Intelligent water tank defrosting technology
  During defrosting of conventional unit, indoor unit will switch to low pressure side(indoor heat getting) and room temperature will decrease by 4~5°C after finishing defrosting; GMV5 Home adopts creative intelligent water tank defrosting technology. when the heat in external coil water tank is sufficient for defrosting, heat will be got from external coil water tank automatically during defrosting. Indoor temperature fluctuation is within 2°C with no flow noise of indoor unit, which greatly improves heating comfort.
- Auto control technology of water temperature
  The auto control technology of water temperature can realize auto adjustment of floor heating water supply temperature, maintain stable indoor temperature, prevent over-cooling or over-heating and ensure the comfort of user. 
- Independent control technology
  IDU wired controller can independently control the startup and stoppage of floor heating in corresponding room.The unit can detect indoor ambient temperature directly to control the startup and stoppage of floor heating in corresponding room.Compared with previous water heater,it is more energy-saving and capable of providing more comfort.
