11—CONTROL SYSTEM 11.5.3.8 Accumulative correction value storage For each combination of active IDUs, the accumulated EEV correction value (for each IDU) will be stored in the memory. Default correction values after power up are zero. 11.5.4 Outdoor Fan Speed Control The OFAN operation keeps the outdoor heat exchanger temperature within a prede ned values by increasing or reducing the OFAN speed. Whenever the OFAN speed is abnormal, the OMT and OCT sensors need to be checked. 11.5.4.

Stop-Rise (SR) – System is in protection, rst level D1 - System is in protection, second level D2 - System is in protection third level Stop-Compressor (SC) – System is in protection fourth level 11.5.8 IDU Protection Level The overall protection level of the indoor units will be the worst protection status among the all indoor units. 11.5.
11—CONTROL SYSTEM 11.5.10 ODU Protections There are 3 ODU protections: ● Compressor overheating ● Heat sink overheating ● System over power Operation logic of all protections is the same. The controlled input (CTT, HST, or PWR) is controlled by changing the protection level using the fuzzy logic algorithm according the input level and the change rate. There are two sets of POWER values, the selection of the values are set according to the state of the Power-Shed dry contact input.

12—TROUBLESHOOTING 12. TROUBLESHOOTING WARNING!!! When Power Up – the whole outdoor unit controller, including the wiring, is under HIGH VOLTAGE!!! Never open the Outdoor unit before turning off the Power!!! When turned off, the system is still charged (400V)!!! It takes about 1 Min. to discharge the system. Touching the controller before discharging may cause an electrical shock!!! For safe handling of the controller, please refer to section 12.5 below. 12.
12—TROUBLESHOOTING No SYMPTOM PROBABLE CAUSE CORRECTIVE ACTION - Repair if needed 10. 11. Compressor operates but one or more units generates no capacity Compressor is over heated and unit does not generate capacity PFC Chock coil Check the PFC Chock coil Burnt fuse Check 20A fuse on the Filter (12.4.2) EEV problem Check EEV (12.4.5) Refrigerant leakage Check refrigeration system (12.
12—TROUBLESHOOTING 12.3 12.3.1 Diagnostics Fault Code for Outdoor unit The last fault occurred in the system will be stored in the EEPROM. If no fault exist in the system, no fault code will be displayed during normal operation mode. For single Split units only, when system enters diagnostics mode (through IDU communication), the last fault code will be displayed even if the system has recover from that fault.

12—TROUBLESHOOTING No Fault Name Fault Description Corrective Action 20 Heat sink Over Heating Compressor stopped due to heatsink protection Check that the air ow around the ODU is free and the fan is running free.
12—TROUBLESHOOTING 12.3.3 DMSMP diagnostics The DMSMP system has 4 IDU LEDs, 1 ODU LED, and 1 Power LED. Each communication channel is built up from receiving and transmitting channels. The outdoor controller is the master of communication (always initiated communication) while the DMSMP and indoor are slave (responds only when it receives). Channel LED Ri has communication The relevant LEDi will be ON. Ri has no communication The relevant LEDi will be Off.
12—TROUBLESHOOTING 12.3.4 Fault Code for Indoor unit Pressing Mode button for long will activate diagnostic mode by the acknowledgment of 3 short beeps and lighting of COOL and HEAT LED’s. When Indoor diagnostics is displayed, all four LED’s (STBY, Operate, Filter, TMR) are on. Entering diagnostics in STBY mode allows only viewing of status (fault-display). In diagnostic mode, system problems / information will be indicated by blinking of Heat & Cool LED’s.
12—TROUBLESHOOTING 12.3.5 Indoor unit diagnostics and corrective actions No.
12—TROUBLESHOOTING 12.4.4 Checking the Reverse Valve (RV) The RV has two parts, Solenoid and valve. Solenoid - Running in heating mode, check the voltage between two pins of reverse valve connector, normal voltage is 230VAC. if no power supply to RV, Check RV operation with direct 230VAC power supply, if OK, replace outdoor controller. Valve — if RV solenoid is OK (as above) but still no heating operation while compressor is On, replace the valve. 12.4.
12—TROUBLESHOOTING 12.4.8.2 EMC troubles to near by home appliances Locations most susceptible to noise: 1. A television or radio is located near the A/C and A/C wiring. 2. The antenna cable for a television or radio is located close to the A/C and A/C wiring. 3. Locations where television and radio signals are weak. Trouble: 1. Noise appears in the television picture, or the picture is distorted. 2. Static occurs in the radio sound. Correction: 1. Select a separate power source. 2.
