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 with wiring detail, in black and white line art with one blue highlight. Top: a dashed box labelled Q4L containing a relay symbol with contacts 13 and 14, with a cable running down from it into the unit. Panel A: view of the open heat pump interior with pipes and components; the cable from the relay box enters the unit through a cable gland at the bottom. Panel B: close-up of the circuit board with a cable coming from the gland to a terminal strip labelled X5M; the cable ends at contacts 13 and 14 of X5M, which are inside a blue rectangle. A small icon above the cable entry shows a hand turning or connecting a wire. Left: a small box drawing with labels A and B pointing to the upper and lower part of the unit.

Wiring diagram combining a photo of a dark square Reduxi Gateway device (logo reduxi and the word Gateway on top) with a terminal strip drawing labelled X5M. The terminal strip shows terminals 3, 4, 5, 6, 9, 10, 13, 14. Terminals 3 and 4 are joined by a switch symbol labelled S4S. Terminals 5 and 6 are joined by a switch symbol labelled S11S, marked with a black circled number 2. Terminals 9 and 10 are joined by a switch symbol labelled S10S, marked with a black circled number 1. Terminals 13 and 14 are bracketed together with the letter a. Four wires run from the black plug connector at the front of the gateway: an orange wire and a blue wire go to terminals 5 and 6 (switch 2), a green wire and a black wire go to terminals 9 and 10 (switch 1).

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.
