Wide Operating Range
Designed for diverse climates, this air-to-water heat pump operates reliably from -28ยฐC to 48ยฐC ambient temperature. It delivers a maximum leaving water temperature of 75ยฐC for heating, as low as 5ยฐC for cooling, and up to 70ยฐC for domestic hot water. Whether you need a cold climate heat pump for severe winters or a high-temperature heat pump for radiator systems, this unit adapts seamlessly. The wide range eliminates the need for additional backup systems in most regions, simplifying installation and reducing overall project cost. It is an ideal low ambient temperature heat pump for commercial and residential HVAC applications.
Flexible System Expansion
This monoblock heat pump supports Dual Zones independent control, allowing simultaneous operation of different emitters such as radiators and underfloor heating. Via RS485 communication, up to 8 units can be connected in a Cascade system, making it suitable for large-scale commercial HVAC projects such as hotels, schools, and office buildings. The cascade function enables staged capacity control, improving part-load efficiency and system redundancy. For B2B HVAC system integrators, this flexibility simplifies design and reduces the number of required models across different project sizes.
Smart Control & High Efficiency
Equipped with a built-in WiFi module and a touchscreen wired controller, this heat pump allows remote monitoring, parameter configuration, and fault diagnosis. It achieves an A+++/A+++ energy efficiency rating, significantly lowering electricity costs. The unit is also Smart Grid ready, enabling automatic power adjustment based on grid load signals. For energy-efficient HVAC solutions, this heat pump integrates seamlessly with building management systems via RS485 and supports 0-10V output for external backup heater or mixing valve control. It is a future-proof choice for smart commercial heating and cooling.
Robust Safety & Protection
Safety is engineered into every layer of this R290 heat pump. It features software-based freeze protection, glycol protection for extreme conditions, and a <100W drain heating belt to prevent condensate freezing in winter. A 3 bar safety valve and water flow switch safeguard the hydraulic system. The unit also complies with EN 60335-2-40 and ISO 817 standards for flammable refrigerant safety. For cold climate heat pump installations, these protections ensure reliable year-round operation and minimize maintenance calls, delivering long-term value to both installers and end users.
FAQs
A thermal monoblock heat pump is an all-in-one outdoor unit that integrates the compressor, heat exchanger, and hydraulic components. This 24kW model uses R290 refrigerant and provides heating, cooling, and domestic hot water. Unlike split systems, it requires no refrigerant piping indoors, simplifying installation. For B2B HVAC projects, it reduces leak risks and commissioning time.ย
This cold climate heat pump operates reliably down to -28ยฐC ambient temperature in heating mode. It uses R290 refrigerant and software-based freeze protection to maintain performance in severe winters. For projects in Northern Europe or North America, it eliminates the need for a backup boiler in most cases.ย
This unit delivers a maximum leaving water temperature of 75ยฐC, making it compatible with radiators and domestic hot water tanks. Cooling mode goes as low as 5ยฐC, and DHW reaches 70ยฐC. It is ideal for high-temperature heat pump retrofits.ย
Up to 8 units can be connected in a Cascade system via RS485 communication, with a master unit (address 0) and up to 7 slave units. This enables large-scale commercial heat pump projects such as hotels and schools. The cascade function improves part-load efficiency and system redundancy.ย
Yes. It features built-in WiFi and a touchscreen wired controller for remote monitoring and parameter setting. It is Smart Grid ready, allowing automatic power adjustment based on grid signals. With an A+++/A+++ energy rating, it reduces operating costs for energy-efficient HVAC solutions.ย
This R290 (A3) heat pump includes software and glycol freeze protection, a <100W drain heating belt, a 3 bar safety valve, and a water flow switch. It complies with EN 60335-2-40 and ISO 817 for flammable refrigerant safety. These features ensure reliable operation in cold climate heat pump installations.ย
The 24kW model is factory-charged with 2.70kg of R290 refrigerant. R290 has a low GWP and high thermodynamic efficiency, helping projects meet green building standards. The charge is optimized for the integrated plate heat exchanger and hydraulic circuit.ย
Yes. It supports Dual Zones independent control, allowing simultaneous operation of two different water temperatures. Zone 1 can serve radiators at higher temperatures, while Zone 2 serves underfloor loops at lower temperatures via a mixing valve. This flexibility makes it suitable for residential and commercial HVAC retrofits.
The installation requires a minimum total water volume of 100 liters, excluding the internal volume of the outdoor unit. The flow rate range is 1.2~4.7 mยณ/h for the 24kW model. Ensuring adequate water volume prevents short cycling and protects the compressor.ย
