9-4. Self-Diagnosis by Remote Control(Check Code)FILE NO. SVM-05020(1) If the lamps are indicated as shown B to G in Table9-3-1, exchanger the self-diagnosis by the remotecontrol.(2) When the remote control is set to the servicemode, the indoor controller diagnoses theoperation condition and indicate the information ofthe self-diagnosis on the display of the remotecontrol with the check codes. If a fault is detected,all lamps on the indoor unit will blink at 5Hz and itwill beep for 10 seconds (Pi, Pi, Pi....). The timerlamp usually blinks (5Hz) during the self-diagnosis.9-4-1. How to use remote control in service mode(1) Press [CHK] button with a tip of pencil to set theremote control to the service mode.• “00” is indicated on the display of the remotecontrol.• The timer lamp on the indoor unit blinkscontinuously. (5 times per 1 sec.)(2) Press [TIMER 8] button.If there is no fault with a code, the indoor unit willbeep once (Pi) and the display of the remotecontrol will change as follows:00 01 02 1d 1E 22• Check the unit with all 35 check codes (00 to 22).as shown in Table 9-4-1.• Press [TIMER 9] button to change the checkcode backwards.If there is a fault, the indoor unit will beep for 10seconds (Pi, Pi, Pi...).Note the check code on the display of the remotecontrol.• 2-digits alphanumeric will be indicated on thedisplay.• All lamps on the indoor unit will blink. (5 timesper 1 sec.)(3) Press [CLR] button. After service finish for clearservice code in memory.• “7F” is indicated on the display of the remotecontrol.• Alphanumeric characters are used for the check code.is 5. is 6.is A. is B.is C. is D.(4) Press [ ] button to release the servicemode.• The display of the remote control returns to as itwas before service mode was engaged.* This illustration in only for Heat pump model.For Cooling only model, there is not the ( ) symbol.− 55 −
