Integrated Thermal Unit
ITU
An integrated thermal management system that combines various thermal components into one unit. All refrigerant circuit components, coolant HV heater, pumps and valves, and temperature sensors are integrated within the unit. The ITU is equipped with an ECU containing the Control SW and covers all heat pump and A/C modes.
