I suppose it isn't the issue of how we want our car temperature, but can the CC be set to stay off as the default setting? Normally it would be set to come on each unlock and start, even if we do switch it off at the panel. Hence my comment above about dealer setting options.
Personally I can't see how anyone can use a car with the CC completely off. Temperature will be all over the place and what about air and controlling humidity? I know for myself in my environment, if the CC wasn't in use, I'd be sitting in a cold and misting car most of the time.
Mine never normally gets touched, it is set to temperature and it does its job. Settings stay in the key memory, so a non event.
