38 CONTROL SYSTEM. CONTROL SYSTEM. General Functions and Operating RulesThe DCI software is fully parametric. All the model dependent parameters are shown in Blue color and with Italic style [parameter]. The parameters values are given in the last section of this control logic chapter of the service manual... System Operation Concept The control function is divided between indoor and outdoor unit controllers. Indoor unit is the system Master, requesting the outdoor unit for cooling/heating capacity supply. The outdoor unit is the system Slave and it must supply the required capacity unless it enters into a protection mode avoiding it from supplying the requested capacity. The capacity request is transferred via indoor to outdoor communication, and is represented by a parameter called NLOAD. NLOAD is an integer number with values between 0 and 27, and it represents the heat or cool load felt by the indoor unit...2 Compressor Frequency Control..2. NLOAD setting The NLOAD setting is done by the indoor unit controller, based on a PI control scheme. The actual NLOAD to be sent to the outdoor unit controller is based on the preliminary LOAD calculation, the indoor fan speed, and the power shedding function. NLOAD limits as a function of indoor fan speed: Indoor Fan Speed Maximum NLOAD Cooling Maximum NLOAD Heating Indoor Fan Speed Maximum NLOAD Cooling Maximum NLOAD Heating Low MaxNLOADIFC MaxNLOADIFH Medium MaxNLOADIF2C MaxNLOADIF2H High MaxNLOADIF3C MaxNLOADIF3H Turbo MaxNLOADIF4C MaxNLOADIF4H Auto MaxNLOADIF5C MaxNLOADIF5H NLOAD limits as a function of power shedding: Mode Power Shedding OFF Power Shedding ON Cooling No limit Nominal Cooling Heating No limit Nominal heating..3 Target Frequency Setting..3. Target Frequency Setting for YBDE 009/02/08/024 The compressor target frequency is a function of the NLOAD number sent from the indoor controller and the outdoor air temperature. Basic Target Frequency Setting: Up to SW 35V2 NLOAD Target Frequency [Hz] <0 0 0 MinFreqC in cool OR MinFreqH in heat mode -26 NLOAD (as long it is in the allowed range, if not, the MinFreqC or Max FreqC in cool mode OR MinFreqH or MaxFreqH in heat mode will be selected). 27 MaxFreqC in cool OR MaxFreqH in heat mode.

Acknowledgment is by 3 short beeps and lights of COOL and HEAT LED s. Then, every short pressing of Mode button will scroll between Indoor and Outdoor unit diagnostic modes by the acknowledgment of 3 short beeps and lighting of COOL and HEAT LED s. During the Outdoor unit diagnostics all four Indoor LED s (STBY, Operate, Filter and Timer) are blinking. When Indoor diagnostics is displayed, all four LED s (STBY, Operate, Filter and Timer) are ON. 2-2 SM CNE -A. GB

66 TROUBLESHOOTING When system enters diagnostics mode, only one fault code is shown. Order of priority is from the lower to the higher number. Diagnostics is continuously ON as long as power is ON. The current system operation mode will not be changed. If no fault occurred in the system, no fault code will be displayed during normal operation mode. The last fault code will be displayed even if the system has recovered from that fault. The last fault will be deleted from the EEPROM after the system has exit diagnostics mode. In diagnostics mode, system fault / status will be indicated by blinking of Heat & Cool LEDs. The coding method will be as follows: Heat LED will blink 5 times in 5 seconds, and then will be shut off for the next 5 seconds. Cool LED will blink during the same 5 seconds according to the following Indoor / Outdoor unit tables: Note: 0 OFF, -ON 2.3. Indoor Unit Diagnostics Alarm Output The Alarm Output dry contact will be on (closed), when a prede ned set faults occur. The fault set is de ned under diagnostics section. The alarm output will be off (open), when the prede ned fault is cleared. The indoor alarm outputs are de SM CNE -A. GB 2-3

Using MegaTool requires: A computer with RS232C port. A connection wire for MegaTool. A special MegaTool software. Use MegaTool according to following procedure: Setup MegaTool software: copy the software to the computer. Connect RS232C port in computer with MegaTool port in Indoor/Outdoor unit controller by the connection wire. Run the software and choose the COM port, you can monitor the A/C system state in monitor tab. 2.5 Simple procedures for checking the Main Parts 2.5. Checking Mains Voltage. Con rm that the Mains voltage is between 98 and 264 VAC. If Mains voltage is out of this range, abnormal operation of the system is expected. If in range check the Power (Circuit) Breaker and look for broken or loosed cable lugs or wiring mistake(s) Checking Power Input. If Indoor unit power LED is unlighted, power down the system and check the fuse of the Indoor unit. If the fuse is OK replace the Indoor unit controller. If the fuse has blown, replace the fuse and power up again. Checking Power Input procedure for the Outdoor unit is the same as with the Indoor unit Checking the Outdoor Fan Motor. Enter Test Mode (where the OFAN speed is high) Check the voltage between lead wires according to the normal value as following: Between red wire and black wire: 30VDC +/- 20V Between orange wire and black wire: 5VDC +/- V Between yellow wire and black wire: 2-6VDC 2-6 SM CNE -A. GB

70 2.5.4 Checking the Compressor. TROUBLESHOOTING The compressor is brushless permanence magnetic DC motor. Three coil resistance is same. Check the resistance between three poles. The normal value should be below 0.5 ohm (TBD) Checking the Reverse Valve (RV). Running in heating mode, check the voltage between two pins of reverse valve connector, normal voltage is 220VAC Checking the electrical expansion valve (EEV). The EEV has two parts, drive part and valve. The drive part is a step motor; it is ringed on the valve. Check the drive voltage (2VDC). When Outdoor unit is power on, EEV shall run and have click and vibration. 2.6 Precaution, Advise and Notice Items 2.6. High voltage in Outdoor unit controller. Whole controller, including the wires that are connected to the Outdoor unit controller may have the potential hazard voltage when power is on. Touching the Outdoor unit controller may cause an electrical shock. Advise: Don t touch the naked lead wire and don t insert nger, conductor or anything else into the controller when power is on Charged Capacitors Three large-capacity electrolytic capacitors are used in the Outdoor unit controller. Therefore, charging voltage (380VDC) remains after power down. Discharging takes about four minutes after power is off. Touching the Outdoor unit controller before discharging may cause an electrical shock Additional advises When disassemble the controller or the front panel, turn off the power supply. When connecting or disconnecting the connectors on the PCB, hold the whole housing, don t pull the wire. There are sharp fringes and sting on shell. Use gloves when disassemble the A/C units.
