Scheduling isn’t working properly

 

y

Have you set the calender and time?

Scheduling cannot operate if you set the calender and time but neglect to register the schedule.

 

y

Are the current settings for the date and time correct?

If the current time is not set properly, the schedule may be starting at another time.

The distribution ratio always becomes 100%

 

y

Check the distribution group and area group settings.

If you put only one area group in a single distribution group or only one indoor unit in a single area group, 

the distribution ratio will always be 100%, and the calculations are meaningless.

The power turns off unexpectedly

 

y

Has the screen turn off automatically?

The power is still on, so try touching the screen.

 

y

Irrespective of the set time, the screen may turn off at start up.

The display is taking a long time to update even after 

performing operations with the screen.

 

y

Depending on the communication status of the connected air conditioning units, it may take some time. 

The screen will update if you wait a moment.

There may be some dots on the screen that do not light or stay lit constantly, but this is not indicative of a 

malfunction.

changes in temperature, etc., but this is not indicative of a malfunction.

After long term use, there may be a shift in the positioning of the operating positions on the touch panel 

compared to the screen’s position.
