In the case of the nanoe™ X module status other than "Normal" or "Unsupported"
If the menu "13. nanoe" is not displayed or the module status becomes other than "Normal" or "Unsupported"
even though the nanoe™ X module is connected, there is a probability that the following symptoms happen.

Countermeasure
Display
The probability of occurrence of nanoe™ X is deviated
from the room temperature and humidity conditions.
Outside the range of temperature: Below 5°C or over 35°C
Outside the range of humidity: Over 86%
There is no abnormality in the
nanoe™ X module. Use in the range of
appropriate temperature and humidity.
Abnormal humidity sensor Humidity sensor not connected or sensor failure
Check if connected to the indoor unit
PCB of the humidity sensor or replace
the sensor.
Disconnection failure
The wiring between the indoor unit and nanoe™ X module
is not connected.
Specialize the target indoor unit and
check the connection to the indoor unit
PCB of the nanoe™ X module.
Not connected
There is no abnormality in the nanoe™ X module. Use in
the range of appropriate room temperature and humidity.
*Specialization of the indoor unit can be checked by the operation of the airflow.
Checking method:
1. Stop the maintenance function.
Press the
button to show the maintenance func display. Then press the
button.
2. Operate the airflow.
Select the Unit no. under the
"2. Airflow setting". Make the airflow setting.
The unit which is corresponded to the preset flap operation will become the target unit.
When the unit is specialized, switch off the earth leakage circuit breaker and unplug the connector of the
nanoe™ X module wiring from the PCB. Then plug it in again. Switch on the earth leakage circuit breaker and
once again check the Steps 1 to 3. Then check the status by selecting the menu "13. nanoe". If "Disconnection
failure" or "Not connected" appears on the display, it is necessary to replace the nanoe™ X module with a new
one.
