The Akva Lux II Se covers both the DHW and heating requirements of large and small single-family houses and is also suitable for large projects.
Akva Lux II Se (A230)
Application
The Akva Lux Se (ECL310/A230) is a fully insulated local and district heating compact substation for space heating and instantaneous domestic hot water production, featuring unique domestic hot water control technology via the PTC2+P controller with energy-saving function. Prepared for wall mounting, the Akva Lux Se covers both the domestic hot water and heating demands of large as well as small single-family houses and is also suitable for large-scale projects.
Equipment
The compact substation is available in three standard versions with a plate heat exchanger for domestic hot water preparation, type XB 06H-1 26, XB 06H-1 40 or XB 06H+ 60. The equipment includes a safety valve, non-return valve for the cold water supply, shut-off valves, sensors, ball valves, sensor pockets, AVPL differential pressure controller, thermostat, strainer, bypass, energy-saving PTC2+P domestic hot water controller and a heat meter spacer piece in the district heating return line. The substation is supplied as standard with an ECL 310 weather-compensated electronic controller and is also prepared for DHW circulation operation.
Domestic Hot Water
Domestic hot water is heated via the plate heat exchanger. The PTC2+P controller regulates the domestic hot water temperature without auxiliary energy and with an energy-saving function, depending on the primary temperature and differential pressure. The pressure-controlled section ensures that the heat exchanger is supplied with flow on both the primary side (DH) and secondary side (DHW) only during water draw-off and is closed immediately after draw-off ends. This largely protects the heat exchanger against limescale and bacterial growth. At the same time, the PTC2+P controller ensures a constant domestic hot water temperature even under fluctuating differential pressure conditions. The Danfoss PTC2+P controller with integrated differential pressure controller and energy-saving function ensures that the plate heat exchanger remains cold in standby mode.
Bypass (Thermostatic Circulation)
A thermal bypass ensures that hot domestic water is available immediately at all times. The temperature is set to provide the best possible comfort and efficiency. The station is supplied as standard with bypass operation but is prepared for operation with a DHW circulation system.
DHW Circulation
If a circulation line is available in the building installation, a DHW circulation kit is available as an accessory and must be ordered separately. The circulation temperature can be adjusted independently of the controlled DHW temperature. This ensures maximum hot water comfort with minimal standby losses and economical operation.
District Heating Meter
The station is equipped with a 3/4" spacer piece in the return line for installation of a district heating meter.
Operation
The station is very user-friendly and easy to install. The compact substation prepared for wall mounting contains connection nipples secured by a retaining bracket. These enable easy and precise installation. The removable cover plate in the front insulation provides easy access to important components such as the controller, the PTC2+P controller and the heat meter calculator.
EvoFlat 4.0 M - Demand control
Product
The EvoFlat 4.0 M combined with the ICON2 floor heating controller provides intelligent, demand controlled regulation for apartment and room heating. Using a self‑learning, patented algorithm, the system continuously evaluates actual heat demand and automatically adjusts the supply temperaturefor optimal comfort, energy efficiency, and hydraulic balance. It responds quickly to changing conditions, integrates seamlessly with modern heat sources, and supports remote monitoring and control via the Ally app. Fully compliant with European energy performance standards, it offers a scalable, future‑proof solution for both small and multi‑zone installations.
The innovative unit sets new standard. It consists of functional blocks made of a specially reinforced PPS composite material. This makes the station extremely lightweight and limits internal heat emission. The smooth surface reduces the risks of scaling and clogging. All components are assembled with newly designed click‑fit connections.
Primary side (DH)
The flat station is equipped with two differential pressure controller and a central strainer. A summer bypass keeps the supply line warm during standstill. This ensures a fast response time for DHW during the summer. The bypass is thermostatically controlled.
Heating (HE)
Supply temperature is adjusted according to the actual heating demand from all connected rooms, ensuring optimal comfort. The controller identifies misbalanced loops and adjusts the opening cycles according to this (automatic hydraulic balancing). A safety thermostat closes the flow at 55°C. A highly efficient circulation pump is installed. A bathroom radiator or towel dryer can be connected using an optional high‑temperature connection set.
Domestic hot water (DHW)
Four sizes of heat exchanger are available to cover all requirements from 45 kW up to 70 kW. The Evoflat 4.0 M is equipped with an intelligent controller that regulates the supply side flow based on the domestic hot water temperature and the volume of water drawn. The station features an integrated differential pressure controller on the supply side of the domestic hot water heating system. This eliminates the need for hydraulic balancing of the station. If necessary, the station can be expanded with a hot water circulation set.
EvoFlat 4.0 PRO M
The Danfoss EvoFlat 4.0 PRO M is an electronically controlled flat station in which the domestic hot water temperature and the heating supply temperature are regulated electronically. It is particularly suitable for use in multi- family buildings with central heating systems.
The electronic controller, in combination with specially developed actuators, enables precise temperature regulation. Online access allows all relevant operational data to be viewed, while meters can be read and displayed simultaneously via the M-bus interface.
This innovative unit sets new standards. The functional blocks are made of reinforced PPS composite material, making the station lightweight and reducing internal heat emissions. The smooth internal surfaces of the pipes minimize the risk of deposits and blockages.
All components are assembled using advanced Click- Fit connectors in a modern design. Compared to conventional stations with pipe and screw connections, this new connection technology eliminates the need for retightening during installation and commissioning.
Primary side
The apartment station is equipped with two differential pressure regulators and a strainer. A summer bypass can maintain the supply line temperature during periods of inactivity, ensuring a rapid response time for domestic hot water heating. The bypass can be operated either continuously or according to a weekly schedule. A return temperature limitation function is included as standard.
Secondary side
The electronic flat station can be configured to regulate the supply temperature using four different control modes: outdoor temperature, room temperature, fixed supply temperature, or offset relative to the supply temperature of the primary side. The combination of electronic control and the differential pressure regulator ensures optimal operating conditions.The controller includes a safety temperature limitation function for the surface heating system. A high-efficiency circulation pump is installed in the mixing circuit to supply the surface heating. Using an optionally available connection set, a bathroom radiator can be connected to the station’s high- temperature circuit and controlled via a week program in the controller.
Domestic hot water ( DHW)
Four heat exchanger sizes are available to cover all requirements from 37 kW to 70 kW. The EvoFlat 4.0 PRO M is equipped with an actuator for regulating the domestic hot water temperature. This actuator adjusts the primary- side flow rate according to the hot water temperature and the draw-off volume. The station features an integrated differential pressure regulator on the primary side of the domestic hot water heating system, eliminating the need for hydraulic balancing between the station and the primary side. If required, the station can be expanded with a domestic hot water circulation set.
