Setting temperature 

is maintained by 

repeating cooling 

and heating.

• When CONT. RUN is selected

The sub-engine runs at two speeds. It starts by 
pressing the cabin controller’s [RUN/STOP] switch 
and when the room temperature is higher than the 
temperature set on the thermostat, it runs at high 
speed cooling, then changes to low speed cooling 
when the room temperature nears the setting 
temperature and stops automatically when the 
temperature drops to 1ºC lower than the setting 
temperature. When the room temperature is lower 
than the temperature set on the thermostat, it 
changes to high speed heating, then when the 
temperature nears the setting temperature, it 
changes to low speed heating, then stops 
automatically when the temperature becomes 1ºC 
lower than the setting temperature.

It starts by pressing the cabin controller’s 
[RUN/STOP] switch and when the room 
temperature is higher than the temperature set on 
the thermostat, it begins a cooling operation. When 
the room temperature is below the setting 
temperature, it carries out a heating operation 
automatically.
Furthermore, it runs continuously, changing back 
and forth continuously between low speed cooling 
when the temperature is higher than the setting 
temperature and low speed heating when the 
temperature is lower than the setting temperature.

ADVICE

Select this only for refrigerated 
products, and do not select for frozen 
products.
