A diffuser is provided with three discharges. Two of the discharges are directed in one direction and, when installed, would be directed towards the outside wall of the conditioned space. The other discharge is directed in the opposite direction and would discharge into the interior of the conditioned space. Responsive to the temperature of the conditioned air being supplied, either one of the two discharges in the one direction or the discharge in the opposite direction is blocked. This results in two discharges in one direction or one in each direction with the discharge area being the same in both instances.
