Precautions in Usage
* Can be turned ON/OFF
** In some cases, refrigeration is shut OFF instead of capacity being reduced.
Absolute high/low limit temperature (& humidity) alarms and upper deviation limit temperature
alarm.
The absolute high/low limit alarms are completely independent of the target temperature and humidity.
They do not change when target temperature or humidity are changed.
Conversely, the upper deviation limit alarm is relative to the target temperature. If the target temperature is
changed, the deviation alarm temperature changes in proportion.
