>>1071312That's a curious observation considering all E233 uses the JR East copy and paste standard 60 kW AU726. Could be the settings applied by the crew? Literature notes the "standard" setting should be 24°C on that line too, slightly lower than the standard of other companies. Maybe it's sensor related. Would you say other single unit trains like Tokyu 5000 and Tokyo Metro trains are colder? Or the older trains with lots of smaller units (though total capacity roughly adds to 60 kW)
Then again, I've seen anything from 22°C to 28°C reported in the normal cars on the Yamanote line Trainnet on a 35°C day
