That strain should be fermented at 50-55°F
. Pitching at "room temperature" is counterproductive, since spoilage organisms grow faster than lager yeasts at those temps, and most of the flavor-active fermentation by-products are produced during the early stages of the ferment.
Bring the wort down to ferment temp or slightly lower before oxygenating and pitching the slurry from an appropriate sized starter
. The starter can ferment at room temp since you will pour out the starter beer.
