Diagram of the connection between the Reduxi Controller and a heat pump. Components: Controller (dark Reduxi box with a green display and an Ethernet port on its front); a router icon with Wi-Fi symbol; Heat pump (outdoor unit with fan and an SG Ready badge at its left); Gateway (Reduxi Gateway box with three blue current sensors attached). Teal lines: Controller to router labelled "Ethernet (Modbus TCP)"; router to Gateway labelled "Ethernet (Modbus TCP)" with the note "Wireless or wired" under the router; Gateway to the SG Ready contacts of the heat pump (line from the Gateway up to the SG Ready badge); a vertical line from the Gateway to the heat pump labelled "L1, L2, L3"; a line from the current sensors to a teal box "Heat pump power supply".

Diagram of a heat pump circuit board seen from above, with component labels printed on it: connectors CN21, CN32, CN29, CN42, CN40, CN41, CN22, CN1, CN2, CN5, CN28, CN25, CN8, CN6, CN24, CN16, CN13, CN15, CN18, CN31, CN35, CN36, CN4, CN17, CN11, CN7, CN30, SW9, display DIS1, switches S1, S2, S3, S4. A blue rectangle highlights connector CN35 on the right edge of the board. Four wires run from CN35 down to an orange cylinder (a cable joint or connector) below the board, and from there four wires continue down into a dashed box labelled SMART GRID.

Wiring diagram combining a photo of a dark square Reduxi Gateway device (logo reduxi and the word Gateway) with a drawing of part of a circuit board. Four wires leave the black plug connector at the front of the gateway: orange, blue, green and black. They run to the right and connect to the four-pin connector labelled CN35 on the board edge, between connectors labelled CN31 above and CN36 below. A switch label SW9 is also drawn on the board. A white box at the bottom right reads CN 35.

Diagram (rendered product picture) of a dark grey Reduxi Gateway box, label "reduxi GATEWAY" on top. On its front side a terminal block with printed labels GND, PORT 1 (A, B), PORT 2 (A, B), 5V, and three round sockets labelled I1, I2, I3. Three blue split-core current sensors with black cables are plugged into I1, I2 and I3; the cables hang down in loops in front of the box.

Photo looking into an open blue metal cabinet. Three blue split-core current sensors are stacked at the left, each placed around a conductor. Around them are many cables: white, grey, blue, yellow-green and black wires, blue network cable, an orange wire connector in the middle and a terminal strip at the lower right. Floor tiles are visible at the lower left. No text or markings are legible.

Screenshot of the left sidebar of the Reduxi Configurator. Top: reduxi logo with the text CONFIGURATOR. Collapsed sections: Devices (plus icon) and Strategies (plus icon). Below, two buttons side by side: Add device (plus icon, marked with a blue highlight box) and Add strategy (plus icon). Below them two entries: Settings and Profile. The area to the right of the sidebar is empty white.

Screenshot of the Reduxi Configurator add-device wizard, step 1 of 3. Progress bar with three steps: 1 Basic settings (active, black circle), 2 Communication channel (grey), 3 Advanced settings (grey). Heading: Basic settings. Fields: Device type * : empty dropdown; Type * : empty dropdown; Name * : empty text field. Buttons: Back (bottom left), Next (bottom right, dark).

Screenshot of the Reduxi Configurator add-device wizard, communication step, partly cropped at the top (step tabs cut off). Heading: Communication channel and device configuration. Fields: Connection *: TCP-IP; IP *: gateway.local; Port *: 502; Modbus unit ID *: 1. The image is cut off below the Modbus unit ID field.

Screenshot of three input rows of the Reduxi Configurator communication channel form, each a dropdown with a small grey caption below it. Row 1: label CT- L1, selected value Auto detect from gateway, caption Current transformer. Row 2: label CT- L2, selected value Auto detect from gateway, caption Current transformer. Row 3: label CT- L3, selected value Auto detect from gateway, caption Current transformer.

Screenshot of a text box with four numbered rules, in English. 1. When EVU signal is on, and SG signal is on, as long as the DHW mode is set to be valid, the heat pump and IBH will operate in DHW mode at the same time automatically. When T5 rises to 60°C, the DHW mode will exit and switch to cooling/heating mode normally. 2. When EVU signal is on, and SG signal is off, as long as the DHW mode is set to be valid and the mode is on, the heat pump and IBH will operate in DHW mode at the same time automatically, when T5≥Min(T5S+3,60), the DHW mode will exit and switch to cooling/heating mode normally. (T5S is the setting temperature). 3. When EVU signal is off, SG signal is on, the unit operates normally. 4. When EVU signal is off, and SG signal is off, the unit operates as below: The unit will not operate DHW mode, and the IBH is invalid, disinfect function is invalid. The max running time for cooling/heating is SG RUNNING TIME, then unit will be off.

Screenshot of a Reduxi Configurator settings form with eight dropdown fields, each with a grey hint line below. Off - relay 1: Off (hint: Setpoint of the relay 1 when heat pump setpoint is off). Off - relay 2: Off (hint: Setpoint of the relay 2 when heat pump setpoint is off). ECO - relay 1: On (hint: Setpoint of the relay 1 when heat pump setpoint is ECO). ECO - relay 2: Off (hint: Setpoint of the relay 2 when heat pump setpoint is ECO). ON - relay 1: Off (hint: Setpoint of the relay 1 when heat pump setpoint is ON). ON - relay 2: On (hint: Setpoint of the relay 2 when heat pump setpoint is ON). BOOST - relay 1: On (hint: Setpoint of the relay 1 when heat pump setpoint is BOOST). BOOST - relay 2: On (hint: Setpoint of the relay 2 when heat pump setpoint is BOOST).
