Third-party thermostats can be used to control the heat pump. According to the Nulite controller settings, third-party thermostats can manage a single zone or multiple zones, allowing clients to easily turn the unit on/off or change operating modes.
With IPX4 waterproof protection and an operating ambient temperature range of -25°C to 43°C, the unit can work reliably in different outdoor conditions. It supports 55°C domestic hot water, 45°C heating water and 12°C cooling water, making it suitable for multiple seasonal comfort needs.
The NULITE R32 DC Inverter Air Source Heat Pump series supports intelligent control through Wi-Fi, RS485 communication and Tuya/Smart Life platform integration. Users can remotely monitor and manage system operation anytime via smart devices, while RS485 enables flexible connection with building management systems and other control solutions, providing a more convenient, efficient and user-friendly heating and cooling experience.
This heat pump is built around PV DC direct-drive technology. Direct current produced by the photovoltaic array powers the compressor directly, doing away with inverters and batteries to maximise solar energy utilisation. It delivers up to 90% energy savings on sunny days, with an overall energy-saving rate of around 60%. Grid and PV power switch without interruption: the system gives priority to PV power, and utility supply automatically compensates whenever PV generation falls short.
Modbus RTU protocol is built into the unit, enabling seamless integration with building automation and energy management systems. The unit supports real-time monitoring of key operating data—including water temperatures, compressor status, operating mode, fault codes, and energy consumption—and remote control of on/off, mode switching, temperature setpoints, and special functions like quiet mode and legionella disinfection. Through multi-unit networking, several heat pumps can be centrally managed.Clients can connect their control systems to heat pumps for remote monitoring and operation.
Exclusive patented air hood with a precisely optimized profile that guides airflow smoothly, reducing backflow and turbulence while lowering resistance and boosting air volume. Its unique guiding structure prevents hot air short-circuiting, ensuring stable heat exchange temperature difference. The airflow evenly covers the heat exchanger for full utilization of its surface. Optimized tip clearance and edge profile reduce both noise and volumetric loss—delivering quiet operation and high performance in one.
NULITE heat pumps are designed with optimized system integration, supporting key components including an electric heater, expansion tank, and inverter water pump. These components work together to ensure stable water circulation, efficient heating performance, and reliable operation under different application conditions.
The advanced touchscreen controller supports multiple languages, enabling easy operation for global users. With a clear interface and smart temperature management, it provides convenient control of heating, cooling, and domestic hot water functions for a comfortable living environment.
Site Preparation & Unit Placement
Choose a well-ventilated outdoor location with enough space for air inlet, air outlet and maintenance access. Place the R290 inverter air source heat pump on a flat concrete base or anti-vibration bracket. Keep the unit stable, level and away from enclosed or poorly ventilated areas.
Water Pipe Connection
Connect the heat pump to the buffer tank, domestic hot water tank, floor heating, radiators or fan coil system according to the project design. Make sure the water inlet and outlet are connected correctly. Pipe insulation is recommended to reduce heat loss and improve heating efficiency.
