3712 Protection Control12.1. Time Delay Safety Control• Compressor will not start for three minutes after stop of the operation.12.2. 30 Seconds Forced Operation• Once compressor starts the operation, it will not stop its operation for 30 seconds. However, it can be stopped with the remotecontroller or the Auto button on the indoor unit.12.3. Total Running Current Control1. When the total running current exceeds l1, compressor operation frequency is reduced. If it reaches below l1, the operationfrequency is increased. (But, up to programmed frequency.)2. If total running current exceeds l2, compressor is stopped immediately.3. If it happens three (3) times within 20 minutes, operation will be stopped and Timer LED blinks. (“F98” is activating.)12.4. IPM (Power transistor) Protection Control (DC Peak detectionAbnormal Current Control• If inverter load current (DC peak) exceeds a rated value, compressor will be stopped immediately. When the excess occurswithin 30 seconds after operation, it restarts in 1 minute and when after 30 seconds, restarts in 2 minutes.• If the excess continuously occurs 7 times within 30 minutes after compressor starts, the unit will be stopped and timer LED onthe indoor unit will be blinking. (“F99” is to be confirmed.)IPM Overheating Prevention Control• If temperature of IPM exceeds 103qC, compressor will be stopped. It will restart in 2 minutes. Temperature for restarting: 90qC.• If the excess occurs 7 times within 30 minutes after compressor starts, the compressor will be stopped and timer LED on theindoor unit will be blinking. (“F96” is to be confirmed.)12.5. Compressor Overheating Prevention Control1. If discharge pipe temperature exceeds 100qC, compressor power will be limited.2. If discharge pipe temperature exceeds 112qC, compressor will be stopped.3. If the above excess occurs 4 times per 10 minutes, timer LED will be blinking. (“F97” is to be confirmed.)12.6. Outdoor High Pressure Prevention Control (Cooling and Dry operations)1. If outdoor heat exchanger temperature exceeds 63qC in cooling or dry operation, compressor will be stopped.2. Timer LED is not blinking. (“F95” is memorized, then.)12.7. Compressor Protection Control (Refrigeration Cycle Abnormality)In cooling and Dry operations1. When compressor is operated continuously for 5 minutes in the maximum cooling power: a running current of 0.7 - 1.4A and“[Indoor intake air temperature] - [Indoor heat exchanger temperature]” < 4qC, compressor will be stopped.2. If the above excess occurs twice for 20 minutes, timer LED is to be blinking. (“F91” is to be confirmed.)In Heating operation1. When compressor is operated continuously for 5 minutes in the rated heating power: a running current of 0.7 - 1.4A and“[Indoor heat exchanger temperature] - [Indoor intake air temperature]” < 5qC, compressor will be stopped.2. If the above excess occurs twice for 20 minutes, timer LED is to be blinking.
