Key Functions:

R290 environmental refrigerant:

R290 is one of the best refrigerants available for mass production upto now: Negligible Global Warming Potential (GWP) and degradation time is considered in monthes, Zero ozone layer depletion potential (ODP); Permanent green, Less load for the same performance, Low energy consumption and higher efficiency.

*Comparison of refrigerant GWP values.

DHW tank disinfection:

The DHW tank disinfection function is used to kill legionella by 65°C water to ensure the health and safety.
 

 

Smart control system:

1. Smart logic to run between hot water and domestic heating, satisfying different heat demands.
 

2. 8 different languages available, user-friendly for many countries.
 

3. Combination of multi-heat source, E-heater, solar panel or boiler etc, heat your house intelligently.

Powerful heating with high efficiency:

1. Little capacity attenuation at -10°C ambient temperature.

2. Operation temperature down to -25°C, reliable system guarantees a warm winter.

3. Maximum LWT upto 75°C, more efficient for radiator users.

4. Energy efficiency level: W35 A+++/ W55 A++, complying EU with standard.

ECO mode:

Once ECO mode is slected, the unit sets the outlet water temperature automatically according to the outdoor ambient air temperature. function.

Wifi App Control:

1. Control your heat pump wherever you are.

2. Pay less bills by setting weekly timer.  

3. Real-time monitoring heat pumps online .

4. Immediate alarm on system faults or protections, easy found easy solved.

5. Easy access for service by modifying 100 + parameters settings online.

Inverter Technology:

Full DC inverter technology is adopted to ensure fast start, avoid frequent start and stop, low noise, high energy efficiency.
 

1. DC Inverter Compressor

Intelligently match the operating frequency according to the load, and intelligently output on demand
