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.
A demand signal is determined and transmitted to the Multi controller microprocessor in the form of
operation commands. (i.e. ON / OFF, cooling or heating (M104-1 and F104-1 only) operation mode,
operation demand frequency). 

The Multi controller microprocessor receives operation commands from all Indoor units connected,
calculates the accumulative operation command and transmits this information to the Outdoor unit Interface
microprocessor.

The Interface microprocessor calculates the capacity required for heating (M104-1 and F104-1 only) or
cooling and determines the operation mode of the Outdoor unit and the actual frequency of the compressor.
