• Rating: 5.1 V / 3 A
• Role in the experiment: Raspberry Pi power supply
• Purchase information: Amazon.co.jp — Miuzei Raspberry Pi 4 USB-C 5.1 V / 3 A power supply

NORITZ remote-controller-related equipment

Kitchen remote controller identified in the experiment record

• Model: RC-G057MPW-2
• Role in the experiment: display reference for heat-pump instantaneous power and accumulated electrical energy

Current related purchase information

• Amazon listing: RC-G057PEW-2 Multi set
• Purchase information: Amazon.co.jp — NORITZ RC-G057PEW-2 Multi set

The Amazon RC-G057PEW-2 Multi set designation is not the same model string as the RC-G057MPW-2 kitchen remote controller recorded in the experiment. The link is therefore presented as related current purchase information, not as evidence that the listed set is identical to the experiment-used system. Compatibility with the water-heater, storage-tank, and heat-pump units must be checked separately.

Equipment not used in this experiment

A multimeter, oscilloscope, and suitably protected logic-analyzer interface are possible tools for a future internal two-wire investigation, but they were not used in AIEL-2026-0003. They are therefore not presented here as experiment-used purchase items.

How purchase information is used

Purchase links are supporting information intended to make the experiment environment easier to identify or reconstruct. A currently sold product is not assumed to have the same production date, internal components, firmware, or connected-system configuration as the equipment used during the experiment.
