  • Page 6: Outline Of Control System

    2. OUTLINE OF CONTROL SYSTEM The refrigerant and electrical systems of the Super multi air conditioner are controlled by the Multi controller and the Outdoor unit microprocessors. All RAV Heat Pump, R407C, 4 series Indoor units are compatible with the Super multi system. i.e. 1 ~ 5 HP. For system operation, initially the microprocessor in each Indoor unit calculates the difference between the current room temperature (TA) and the requested temperature which has been set on the Remote controller.
