5-3 Change of Setting temperature
Caution
It is basically recommended to maintain the initial set value of 35
℃ .
Setting at an unnecessarily low
value may cause excessive condensation and excess amount of drainage water.
Turn on the COOLCABI. The current internal temperature is displayed.
Press the SET button. The current setting temperature is displayed with flashing.
3 Change the setting temperature using the Up and Down buttons within the range between 3
℃ to 45 ℃ .
actory setting: 35 ℃
4 Press the SET button to save the setting. The current internal temperature is displayed again.
5-4 orced cooling operation for inspection purpose
Hold down the Up and Down buttons at the same time for more than 3 seconds.
The operation lamp blinks and COOLCABI starts forced cooling operation. After the amount of time set by the
parameter elapses, COOLCABI will return to normal operation.

5-5 Parameter setting
enerally, there is no need to change the setting of parameters. If necessary, follow the procedures described
below.
○Hold down the SET button for more than 3 seconds when an internal temperature is displayed.
Parameters are displayed in the following order. Press the SET button to move to the next parameter.
Display the parameter desired to be changed and set the value using the Up and Down buttons. Press the
SET button to save the change.
・ Differential d Default: 5 ℃ Setting range: 3 to ℃
This indicates the temperature difference against setting temperature at which the compressor stops.
Caution: Setting of the temperature and the differential value should be made so as to avoid
repetition of compressor’s on off operation of 6 or more times in an hour.
・
orced cooling operation time Cd Default: 6 (60 sec) Setting range: to 3 to 3 sec
This is to set the time of forced cooling operation which is executed when the Up and Down buttons
are pressed for more than 3 seconds at the same time.
・
High temperature alarm AL Default: 45
℃
Setting range: 35 to 5
℃
This is to set the temperature at which High temperature alarm E outputs.
・
Differential for High temp. alarm dA Default: 2
℃
Setting range: to
℃
This is the differential value for resetting High temp. alarm.
