Table
Silent operation can be set by field setting from the wired remote controller:
Method
When setting mode 16(26)-0-02, quiet (low noise) operation will be carried out by presuming the
current time in accordance with the outside temperature.
Automatic mode will start when the outdoor temperature is = average max of last 10 days -5°C
and will be conducted for 10 hours.
The maximum outdoor temperature is supposed to occur at 14:00h.
As the time judgement is made in accordance with the outdoor temperature, the above
mentioned timing is an estimation only.
Capacity
precedence
setting
When setting mode 16(26)-0-04, the low noise operation will be stopped when the heating or
cooling load increases. In that case, the operation will return to normal operation. The unit will
return to low-noise operation when the heating or cooling load decreases again.
