9.6.4. Self Diagnosis display
The diagnostic displays that appear when trouble has occurred can be checked using the remote control unit.
When trouble occurs, operation is stopped automatically, and the timer lamp blinks. The diagnosis time has been reduced by
warning the user by means of the blinking of the timer lamp.
·
When trouble occurs, operation is stopped automatically, and the timer
lamp blinks.
·
The timer lamp will go off if the power is turned off, but it will start
blinking again if the air conditioner is operated with the trouble left
unremedied.
·
No diagnostic displays will appear when the unit is operated after the
trouble has been remedied. However, the last diagnostic symbol is
stored in the IC´s memory. (This symbol can be cleared.)
·
When the air conditioner protection operation is triggered because the
air conditioner is being operated under overload conditions, its heat
radiation is being interfered with or anti-freezing operation is initiated or
because its supply voltage has dropped or its power has been turned
off and then back on during operation, for instance, no diagnostic
displays will appear. However,

stored in the IC´s memory: this is normal and not indicative of
malfunctioning.
