I am a new user of the Tempest, and I use it exclusively with an IH
With the wand, the clicks depend on the glass bowl position, if I push it up till the end, I count ten seconds after the 2nd click, that the wand continues heating. Yesterday I reread the online manual, and pushed the glass bowl couple of millimeters down, this way there is no 2nd click at 280 Celsius setting.
However, this way works like the Anvil, i.e. finish the load in a long first draw, which produces huge vapor and then second draw produces way less vapor with burned taste.
