Modutherm’s Nordflex+ controller provides optimum system efficiency
Following the successful launch of its range of high efficiency heat pumps, Modutherm has introduced the NordFlex+ Wi-Fi controller.
Designed specifically for use with the company’s range of AW Monobloc heat pumps, the NordFlex+ is BMS compatible and allows up to 16 units to be operated from one device. Controllability is further enhanced by its remote monitoring capabilities, with the operating parameters also easily accessed via a mobile app.
The NordFlex+ uses cascade logic to ensure the heat pump system always achieves the highest COP. The controller manages the compressor speed of all the heat pumps in a system to maximise efficiency in line with heating demand. This ensures the running time (and fuel consumption) of the heat pumps is evened out for optimum system efficiency and reliability. A single “daisy chain” data cable creates a control network of heat pumps and NordFlex+, so an isolated power supply to each outdoor unit minimises cable installation.
The controller is capable of simultaneously handling up to four mixed heating/cooling circuits with different temperature zones. This is achieved by prioritising the heating circuit with the highest heating demand to run the system, while adjusting down to the temperature for the rest of the circuits simply by controlling the mixing valves. All the necessary settings can be easily adjusted on the touchscreen display, enabling the creation of simultaneous cooling, heating and DHW production.
A key benefit of the NordFlex+ is its multifunctional control capabilities, allowing it to be designed into a huge range of projects without the need for any additional programming. To simplify commissioning, engineers can preconfigure the control to suit a building’s heating system, so it is ready to use when it arrives onsite.
As it is designed for hybrid systems, it works with a range of additional heating technologies and systems, including boilers, district heating networks and heat pumps. Indeed, using the NordFlex+ controller’s configuration tool allows for the creation of a hybrid, flexible and futureproof system, incorporating heat pumps and other energy sources. With the addition of an expansion board, it can even connect multiple buildings such as factories, offices and housing, as well as create a small district heating grid, also known as a ‘microgrid’.
