The 5-inch colorful touch screen allows you to control the temperature and set the system modes easily. With modern and clear interface, it can quickly check error codes, making sure that you are able to change or program your room temperature at anytime, anywhere.


These EVI low temp DC inverter heat pumps are specially designed for chilly climate areas. The SPRSUN self- developed controller series combine eco-friendly R32 refrigerant and inverter EVI technology to produce 60°C hot water as well as stable house heating even under -30°C low temperature condition. Adopting the Panasonic rotary compressor, the EVI inverter heat pumps significantly improve the problem of insufficient heating efficiency at low temperature.


If there's a necessary software update, the system will keep you informed so that you can upgrade the controller software with one click anytime, anywhere as long as it connects to the internet. The update can take several minutes depending on the speed of the internet connection.


As highly energy-efficient as the CAREL controller series, the new R32 Full Inverter Heat Pumps are also can achieve ERP A+++ energy level. They have a maximum heating capacity from 9.5KW to 22KW, with a maximum COP of 5.89.


The R32 refrigerant is more environmentally friendly compared to other traditional refrigerants. Its ability to enable an inverter heat pump to recharge and recycle more effectively than some other refrigerants means that the unit can run at much higher efficiencies.


Panasonic rotary compressor and NIDEC DC inverter brushless fans enable the units to run quietly. Meanwhile, new noise reduction measures are adopted to control the sound of the units at a satisfactory level. The SPRSUN Self-developed Controller Series can realize low noise running of 56dB(A) when testing at sound power.


With the self-developed CGK online intelligent remote-control system, our R32 DC inverter heat pumps are equipped with highly integrated control functions, which can be operated via a remote APP. The system is easy to manipulate, stable in performance, and is truly a smart operating system.


SPRSUN independently developed its own PID intelligent defrosting control mode. When the defrosting conditions are met, the defrosting mode will be automatically entered to prevent the unit from defrosting confusion and energy consumption, which will improve the reliability and economy of the whole unit.


The unit has various human-centered functions: 
> It can automatically switch the temperature mode according to the ambient temperature; 
> Multiple timing functions improve customer experience and meet their energy-saving needs; 
> Multi-language display is designed for customers in different markets; 
> Sterilization is applied to make the heat pump more comfortable; 
> A variety of automatic protection functions are equipped in the unit to identify and adjust errors automatically, so that the unit works more stably and durably.
