The WY-Series is available up to 30 tons and can connect up to 50 outdoor units, while the WR2-Series is available up to 20 tons and connects up to 50 indoor units as well. Both systems feature expanded entering water temperatures of 23° to 113° F. The W-Series units can be installed floor-by-floor inside a building, easily offering a solution for building managers who need to install equipment indoors.
