1-4 Indoor Fan Performance If external static pressure is too great (due to long extension of ducts, for example), the air flow volume may drop too low at each air outlet. This problem may be solved by increasing the fan speed using the following procedure: Booster cable (M - H - HH)
4. FUNCTIONS 4-1. Operation Functions ■ Functions of the main unit controller ■ SENSOR DRY 1 OFF During automatic operation, the system adjusts the room : • Used to stop the unit when the remote temperature and fan speed according to the conditions in the (Self-diagnostics) controller is unavailable.

4-2. Protective Functions ■ Overload prevention during heating ■ Cold-air prevention during heating During HEAT operation, the temperature of the indoor heat During heating, the fan speed is set to “LL” (very low) or stopped. exchanger is used to control the frequency and lessen the load As the temperature of the indoor heat exchanger rises, the fan on the compressor before the protective device is activated.
5. TROUBLESHOOTING ■ Precautions before performing inspection or repair ● After checking the self-diagnostics monitor, turn the power OFF before starting inspection or repair. ● High-capacity electrolytic capacitors are used inside the outdoor unit controller (inverter). They retain an electrical charge (charging voltage DC 280 V) even after the power is turned OFF, and some time is required for the charge to dissipate.

Details of Self-Diagnostics When the operation selector on the grille assy is moved from the ON or TEST position to the OFF (Self-diagnostics) position, the indicator lamps will flash (or remain ON) for 5 seconds and then turn OFF for 2 seconds (buzzer sounds once) to indicate the presence of a sensor failure or the activation of a protective function.

■ If the self-diagnostics function fails to operate • No indicators illuminate and the Check the indoor unit. indoor fan does not turn. • Check the power voltage. Blown Is the fuse blown? Normal Replace the circuit board or the fuse. Replace the controller.

<Noise malfunction and electromagnetic interference> An inverter A/C operates using pulse signal control and high frequencies. Therefore, it is susceptible to the effects of external noise, and is likely to cause electromagnetic interference with nearby wireless devices. A noise filter is installed for ordinary use, preventing these problems. However, depending on the installation conditions, these effects may still occur.
