The valve includes a cylinder located in the housing that includes a plurality of apertures and a fail safe opening. The cylinder is moveable such that one of the plurality of apertures can be aligned with one of the plurality of ports of the housing to determine a flow of a fluid through the valve. The valve includes a moveable feature moveable with and relative to the cylinder, and the moveable feature covers the fail safe opening of the cylinder when a temperature of the fluid flowing through the valve is below a threshold temperature.
