NORITZ kitchen remote controller

• Model: RC-G057MPW-2
• Role in the experiment: display reference for heat-pump instantaneous power and accumulated electrical energy
• Current purchase source: Amazon.co.jp — NORITZ RC-G057PEW-2 Multi set

The linked RC-G057PEW-2 Multi set designation is not the same model string as the RC-G057MPW-2 kitchen remote controller retained in the experiment record. It is therefore shown as a related current purchase source, 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.
