Functions and Control Domestic air conditioner keys for 6 times within 7 seconds, the system will feedback with 6 rings.* After the system enters the separate indoor system operation mode, the indoor system will operateaccording to the set mode and neglect the communication signals of the outdoor system. However, it has tosend signals to the outdoor system.* Quitting condition: This mode can be quitted after receiving the quitting signal from the remote control orurgency system. The indoor system thus can quit the single operation mode.7.1.17 Power cut compensation* Entering condition: Press dormant button 10 times within 7 second, the buzzer will ring 4 times and thepresent system status will be stored into the EEPROM of the indoor system.* After entering the power cut compensation mode, the processing of the indoor system should be as thefollowings:Remote control urgency signal: operate according to the remote control and the urgent conditions, thepresent status will be stored into the EEPROM of the indoor system.* Quitting conditions: Press dormant button 10 times within 7 seconds and the buzzer will ring twice.7.1.18 Fixed frequency operation1. Fixed cooling: a. under G code condition: high speed cooling, set 16ć, press temperature ‘-‘ key and theset key at the same time. The system will enter the fixed frequency operation after the buzzer rings twice.b. The proceeding programs are as the follows:Entering the fixed frequency operation, you can set the fixed strength location 1 and send the cooling signalto the outdoor system. Meanwhile, you can fix the indoor system at high speed mode, the location of theairflow direction board can be switched to the maximal position.c. Quitting condition: The fixed frequency cooling can be quitted after receiving the remote signal, and thesystem will enter the remote setting status.2. Fixed heating: a. under G code condition: high speed heating, set 30ć, press temperature ‘+‘ key and theset key at the same time. The system will enter the fixed frequency operation after the buzzer rings twice.b. The proceeding programs are as the follows:Entering the fixed frequency operation, you can set the fixed strength location 1 and send the heating signalto the outdoor system. Meanwhile, you can fix the indoor system at high speed mode, the location of theairflow direction board can be switched to the maximal position.c. Quitting condition: The fixed frequency heating can be quitted after receiving the remote signal, and thesystem will enter the remote setting status.7.1.19 Test programFirst, connect the test program terminal on the mainboard. Then connect the system to the power circuit. Thetest program will operate as follows.HV series display: The buzzer rings for one time—the signal will be sent to outdoor system for 0.5 second—the violet is sent for 0.5-- the background light turns to white—the back ground light turns to white—thebackground light turns to white—the background light is fully lighted for 0.5 second—LED screen lights for0.5 second— the step-in motor fully output for 0.5 second—then the motor doesn’t output for 0.5second—the motor fully output again for 0.5 second. The test program finishes.20
