R32 environmental refrigerant
1. R32 has a GWP of 675, roughly 30% lower than that of R410A
2. R32 systems use up to 20% less refrigerant than R410A, making them more efficient and cost less to operate
3. Ozone Depletion Potential of 0
4. Easier to recycle than R410A, as R32 is a single component refrigerant
DHW tank disinfection
The DHW tank disinfection function is used to kill legionella by 65°C water to ensure the health and safety.
Climate curve
You can choose different climate correlation curves or your own customised curve. Once the curve is selected, the unit sets the outlet water temperature automatically according to the outdoor ambient air temperature.
Floor preheating and drying
Protect your home floor by activating the Floor Preheating function which slowly increases the heating temperature of the floor coils, avoiding possible floor damaging and transitioning smoothly to the heating function. The Floor Drying Up function provides an additional solution to the installer as it helps remove any residual moisture from newly installed floor coils, further protecting the installation and ensuring the optimal and effective operation of the heat pump.
Powerful heating with high efficiency
1. No capacity attenuation at -l0°C ambient temperature
2. Operation range down to -25°C
3. Maximum LWT reach 60°C
4. Energy efficiency level: A+++
Mode combination
There are 4 single operation mode (Cool,Heat,DHW,Auto) and 3 combined operation mode to meet different demands of using.
Fast DHW
You can select the Fast DHW Function for the unit to produce DHW when there is a need for immediate hot water production.
