Operation
ADVICE
If the room temperature reaches the setting temperature within 3.5 minutes, the battery failure
prevention circuit will activate, allowing heating operation to be entered even during cooling
operation. The temperature width recorded on the recorder mounted in the refrigeration vehicle
may increase at time, but this is not a problem unless it increases greatly.
●
When AUTO START/STOP is selected
Cooling operation will be carried out automatically if the room temperature is higher than the setting
temperature, and heating operation will be carried out automatically if the room temperature is lower than
the setting temperature. When the room temperature reaches -1
°
C of the setting temperature, the sub-
engine will automatically stop, and the compressor, condenser fan and evaporator fan will stop. Note that if
-1
°
C of the setting temperature is reached within 3.5 minutes after starting sub-engine operation, the
operation will automatically change to continuous operation (repetition of cooling/heating operation), to
prevent the battery from dying. If cooling after 3.5 minutes have passed, the unit will stop when the
temperature reaches -2
°
C of the setting temperature, and when heating, the unit will stop when the setting
temperature is reached. Heating will not take place if the temperature is "-7
°
C" or less below the setting
temperature.
●
When CONT.RUN is selected
If the room temperature is higher than the setting temperature, the cooling operation will take place, and if
lower, the heating operation will take place. Continuous operation will take place by repeating cooling and
heating.
