5-1-8. Operation in response to ambient temperature
The storage senses the ambient temperature and adjusts the temperature in the compartments accordingly. This keeps the
storage from being too cold or too warm because of seasonal variations and maintains exact temperatures in the
compartments.
5-1-9. Sequential operation of components
Components (compressor, 3-way valve and left/right seasoning heater) are operated in a specific order to prevent damage
and noise caused by simultaneous operation of all parts when the unit is started and after completing the self-test routine.
