INTRODUCTION 1. INTRODUCTION 1.1 General The SX split floor and ceiling units range comprise the ST (cooling only) and RC (heat pump) models, as follows: • Cooling Only • Heat Pump 1.2 SX9ST SX12ST SX15ST, SX18ST SX24ST SX30ST SX9RC SX12RC SX15RC, SX18RC SX24RC SX30RC Main Features The SX series benefits from the most advanced technological innovations, namely : 1.3 • R410A • Microprocessor control. • Infrared remote control, and on unit.
INTRODUCTION 1.5 Control The microprocessor indoor controller, and an infrared remote control, supplied as standard, provide complete operating function and programming. The unit is designed with an on unit control board as well. For further details please refer to the Operation Manual, Appendix A. 1.6 Outdoor Unit The SX outdoor units can be installed as floor or wall mounted by using a wall supporting bracket. The metal sheets are protected by anti- corrosion paint work allowing long life resistance.

CONTROL SYSTEM 11.15.2 By Remote Control Settings: a. STEP 1: TURNING ON THE POWER. Turn ON the power, make sure that the unit is in operation. b. STEP 2 : ENABLE SELF-TEST MODE c. 1) Use the remote control to send the first settings to display / indoor unit HEAT mode, HIGH IFAN, set temperature to 16 ºC, no I-FEEL Sleep or any other timer settings are needed. 2) Cover the IR transmitter components in the remote control so that it will not transmit the signals to the indoor unit display.
CONTROL SYSTEM d. STEP 3: AUTO LED WALK TEST. 1) All the LEDS will turn OFF. 2) All the LEDS will turn ON for 1 second one by one in the following sequence: STAND-BY Ö OPERATE Ö TIMER Ö FILTER Ö COOL Ö HEAT. 3) e. In PRX all the LEDS will turn ON for 1 second one by one in the following sequence : 18 °c Ö 20 °c Ö 22 °c Ö 24 °c Ö 26 °c Ö 28 °c Ö 30 °c Ö High IFAN Ö Auto IFAN Ö Med IFAN Ö Low IFAN Ö STAND-BYÖ TIMER Ö FILTER ÖCOOLÖ HEAT.
CONTROL SYSTEM Fail condition: 0 sec - STAND-BY is turned ON 3 sec - STAND-BY, OPER, TIMER and FILTER are turned ON When the timing reset test is completed, the next test will start automatically. i. STEP 8: MEMORY TEST (EEPROM) The test purpose is to check if the memory is functioning correctly. The test result is reported by using the STAND-BY and FILTER LEDS: LED Indicator STAND-BY LED FILTER LED Condition for LED to be ON Test passed Test failed AT THIS POINT THE SELF-TEST IS COMPLETED.
CONTROL SYSTEM 11.16 System Diagnostics Pressing Mode button for 5-10 seconds in SB or any other operation mode will activate the DIAGNOSTICS mode, acknowledged by 3 short beeps and lighting of COOL and HEAT LEDs. In DIAGNOSTICS mode, system failures will be indicated by the blinking of HEAT & COOL LEDs. The coding method is as follows: HEAT LED blinks 5 times in 5 seconds, and then turns off for the next 5 seconds. COOL LED blinks during the same 5 seconds according to the following table: No.
TROUBLESHOOTING 12. No. TROUBLESHOOTING SYMPTOM PROBABLE CAUSE 1 Power supply indicator (Red LED) does not light up. No power supply. 2 Unit does not respond to remote control command. Remote control command did not reach the indoor unit. 3 Unit responds to remote control command but operate indicator (Green LED) does not light up. Indoor fan does not start (louvers are opened and Green LED lights up). Problem with display PCB. 4 Change to COOL MODE and check. Problem with PCB or capacitor.
TROUBLESHOOTING No. SYMPTOM 11 One of the protections is activated and compressor is stopped with no apparent reason. Compressor motor is noisy and no suction is present. Control problem or refrigeration system problem. Perform diagnostics to detect active protection, and take action accordingly. Wrong phase order to compressor. Check compressor phase order. Water leakage from indoor unit. Freezing of outdoor unit in HEAT Mode and outdoor unit base is blocked with ice.
