Claim 15:
16. A diffuser assembly for a heating, ventilation, and air conditioning (HVAC) system, the diffuser assembly comprising:
a housing configured to receive an air flow;
a plurality of blades pivotably coupled to the housing and configured to rotate about respective axes relative to the housing; and
a linkage mechanism coupled to the plurality of blades, wherein the linkage mechanism comprises an intermediate linkage configured to selectively pivotably couple to a first linkage of the linkage mechanism or to a second linkage of the linkage mechanism to transition the linkage mechanism between a first configuration and a second configuration, wherein, in the first configuration, the linkage mechanism is configured to induce rotation of the plurality of blades about the respective axes in a common direction in response to application of an input force to a blade of the plurality of blades, and wherein, in the second configuration, the linkage mechanism is configured to induce rotation of a first subset of the plurality of blades in a first direction and induce rotation of a second subset of the plurality of blades in a second direction, opposite the first direction, in response to application of the input force.
