Basic functional layout that shows all mechanical equipment (heat pumps, boilers, circulator pumps, buffer tanks, mixing valves, diverting valves, fan coils and air treatment units) and electric components controlled by the control system. The layout shows the water flow direction for both supply and return lines and will include primary loop and secondary loop.
Note: this is not a full mechanical schematic and is not a stamped engineering drawing. Full mechanical room design shall be up to the project mechanical engineer or hydronic installer. This layout is designed to aid them in their design to ensure proper functionality of the system.
