Though the PS and basic electronics are running 24/7, not just when the A/C is running. Maybe a hypothesis of yours applies here - they got a good deal on transformers suitable for use in a switch mode PS. Of if I were being cynical, which of course, I never am, I might suspect that it was to ensure that the boards were uneconomic to repair (except DIY), thus increasing the market for replacement boards. Although I don't know how much a replacement costs, because 3 days after I asked, Daikin still haven't replied to my email. Sylvia.
