Functionalities

icon-display
5-inch color touchscreen

The 5-inch color touchscreen allows you to easily control the temperature and set the system modes. With a modern and clear interface, it can quickly check error codes, ensuring you can change or program your room temperature at any time.

icon-energy-class
ERP A+++ energy class

Highly energy efficient as the CAREL series controller, the new R32 full inverter heat pumps can also achieve ERP A+++ energy level. They have a maximum heating capacity of 9.5KW to 22KW, with a max COP of 5.89.

icon-software-update
Possibility of software update remotely and with just one click

If a software update is needed, the system will inform you so that you can upgrade the controller software with one click anytime, anywhere as long as you are connected to the internet. The update may only take a few minutes depending on the speed of your internet connection.

icon-r32
R32 Refrigerant

R32 refrigerant is more environmentally friendly than other traditional refrigerants. Its ability to allow the inverter heat pump to recharge and recycle more efficiently than some other refrigerants means that the unit can operate at much higher efficiency.

icon-defrosting
Intelligent defrosting

Niko Therm independently developed its own PID intelligent defrost control mode. When the defrost conditions are met, the defrost mode will be automatically entered to prevent the unit from being confused with defrosting and energy consumption, which will improve the reliability and economy of the entire unit.

icon-max-temperature-65
Max. outlet water temperature reaches 65°C

By combining R32 refrigerant and inverter heating technology, the heat pump can operate from -30°C to 45°C, maintaining high COP and stability. More importantly, the max. leaving water temperature reaches 65℃ without electric heating.
