The new Wednesday era under Garry Monk kicked off with a hard-fought 2-0 success at Huddersfield in front of the Sunday lunchtime Sky TV cameras.
Steven Fletcher’s early strike, his third in as many games, laid the foundations for victory, completed by substitute Sam Winnall late on.
The Terriers, also under new management in the shape of Danny Cowley, arguably shaded possession but Wednesday struck where it mattered to post a remarkable eighth successive clean sheet at the John Smith’s stadium.
The Yorkshire rivals exchanged sighters straight from kick-off, with Adam Reach testing Kamil Grabara at one end while Keiren Westwood thwarted Trevoh Chalobah at the other.
And those openings were appetisers as Fletcher gleefully gobbled up a Kadeem Harris delivery on 13 minutes to put the Owls in front.
The former Cardiff winger beat his man down the left and stood up the ideal cross that the in-form Fletcher headed home with aplomb from close range.
It was the perfect start for Monk and Wednesday, although the Terriers began to find more of their stride after falling behind.
Terence Kongolo nipped in between Moses Odubajo and Westwood midway through the first half but spooned the half chance over the bar.
Kongolo was at the centre of the action again with half time looming, this time cutting inside to test Westwood on the angle and the keeper was equal to the challenge.
The second period began with Wednesday claims for a penalty waved away after Jacob Murphy tumbled under a challenge from Christopher Schindler.
Westwood denied Lewis O’Brien moments later as Huddersfield sought an equaliser before the hosts made a double change to boost their options in the final third.
And the move almost paid dividends on the hour when substitute Juninho Bacuna pulled back for Kongolo, whose driven shot was goal-bound but Westwood was down to his right to parry clear.
The Owls countered with Adam Reach brushing the side netting with a daisycutter before the same player fired straight at a grateful Grabara after good work from Harris.
Then, on 72 minutes, Wednesday doubled their lead with Winnall climbing off the bench to seal the points.
Bannan executed a wonderful feed from the left and Winnall glanced a perfect header into Grabara’s net off the post.
Reach went close to a third with a fierce hit deflected wide and Fletcher was a whisker away from a Liam Palmer cross but it mattered not as Wednesday extended their stunning run of form in the Terriers’ backyard.
Wednesday: Westwood, Odubajo, Borner, Iorfa, Palmer, Murphy (Winnall 60), Hutchinson, Bannan, Harris (Lee 85), Reach, Fletcher (Nuhiu 82)
