谢谢大家
我看上honeywell的,写信去问,人家说不能220v,也不鼓励你用变压器。
Unfortunately, we cannot recommend that any of our products be used in foreign circuits and outlets, even if used with a converter. Our products were not manufactured to be able to handle a power-source change, and using them in an unfamiliar outlet will almost definitely cause a product malfunction. Due to these recommendations, using any unit in this manner will void the Limited Warranty. We sincerely apologize for any inconvenience.
