Outline of judgment

When one of the following phenomena appears, an error of the power relay (RY01) is considered; therefore replace the P.C. board.

•The operation started from the remote controller.

→

•The fan stops immediately.

•The display on the remote controller disappears.

→

After approx. 1minute

30 seconds, "Under setting" is displayed.

→

The screen of the remote controller enters in STOP status.

The primary judgment to check whether a trouble occurred in the indoor unit or outdoor unit is carried out with the following method.

Method to judge the erroneous position by display panel of the indoor unit (lamp display of the wireless receiving part)

The indoor unit monitors the operating status of the air conditioner, and the blocked contents of self-diagnosis are displayed restricted to the following cases if a protective circuit works.

 

 

 

 

 

 

 

 

: Go off,

: Go on,
