Wiring diagram combining a drawing and a photo. Left: a grey box labelled Optional PCB containing a block labelled Digital Input with three connections: BIT1, BIT2 and VCC. Three wires lead from these to the black plug connector of a dark square Reduxi Gateway (logo reduxi and the word Gateway) shown in a photo on the right: BIT1 is a green wire, BIT2 is a blue wire, VCC is an orange wire. The plug has further wires looping at the bottom: orange and blue.

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 from a heat pump user manual. Left: a box titled 11. Bivalent connection with a second box Initial setting: No. Text: Set if heat pump linked with boiler operation. Connect the start signal of the boiler in boiler contact terminal (main PCB). Set Bivalent connection to YES. After that, please begin setting according to remote controller instruction. Boiler icon will be displayed on remote controller top screen. A last line is cut off: After Bivalent connection Set YES, there is two option of control pattern to be select. (SG Ready / Auto). Right: a menu screen titled System setup with the time 12:00am,Mon and entries Tank heater, Base pan heater, Alternative outdoor sensor, Bivalent connection (highlighted in black). Bottom hints: Select, Confirm.

Screenshot of a document page in English. Bullets: SG control = YES or NO. Capacity up setting 1: Heating capacity [50 ~ 150 %] marked with one star; DHW capacity [50 ~ 150 %]. Capacity up setting 2: Heating capacity [50 ~ 150 %] marked with two stars; DHW capacity [50 ~ 150 %]. Heading Control contents: If SG control on remote control = Yes, then following control only activate by digital input. While Digital input is 00 (Normal operation): Normal operation. Once detect 00 system will operate back to normal condition. (All the target set temperature for heating side and DHW side will return back to previous set temperature when digital signal change from 10 or 11 back to 00.) While digital input is detected 01 (HP stop) with one star: Heat pump and room heater and tank heater cannot operate. (Solar control and Boiler back up and 2 Zone control can activate.) While digital input is detected 10 (Capacity 1): Target temperature for heating and DHW Tank is changed according to the percentage set by Remote control setting. Target water temperature of cooling is changed according to the adjustment value set by Remote control setting. However, which setting temperature is change depend on system setting. While digital input is detected 11 (Capacity 2) with two stars: same text as for Capacity 1. A last bullet repeats While digital input is detected 10 (Capacity 1): Setting temperature for heating and Tank is changed. However, which setting temperature is change depend on system setting.
