NOTE
●
What is the automatic start/stop operation?
Inside container temperature is maintained at around the setting temperature by
turning thermostat ON or OFF* for the sub-engine during sub-engine drive, or
turning thermostat ON or OFF for the motor during motor drive. Automatic start/
stop operation consumes less fuel (electricity) than the continuous operation
but has a large deviation on the inside container temperature. This pattern of
operation is suitable for cargos with a larger allowance in the control temperature.
* Thermostat OFF: The action that the sub-engine (motor) stops automatically
after inside container temperature reached to the setting
temperature.
(As the controller is active, it re-starts automatically.)
Thermostat ON: The action that the operation re-starts automatically when the
inside container temperature comes off the designated range
of the setting temperature during thermostat OFF.

What is the continuous operation?
The refrigeration unit operates without turning the thermostat ON or OFF, in which
inside container temperature is maintained at around the setting temperature by
adjusting the refrigerating and heating capacities automatically. Since this
operation can maintain the inside container temperature very close to the setting
temperature, it is suitable for cases such as chilled transportation, which require
strict quality control.
