Central ac is believed to be an air conditioner that many large sites now use. Because your central air conditioning is very comprehensive and power-efficient to achieve a wide range of cooling. But many times, our central air conditioning has a number of problems, big and small, and of course they can be judged by external performance. Then, using the hal central air conditioning (hcac) as an example, the young editor introduced the malfunction code for hal central air conditioning when it went down。
Kvr series maintenance code
1. Determination of the internal engine displaying fault codes: kvr's corresponding wire controller dialled at 1,3 onon, 2 4 on off.
Float, switch, e0
Outdoor malfunction e1
E2 (not shown in kvr)
Fluorine temperature, sensor, malfunction e3
Pneumatic temperature sensor failure e4
Indoor 846 chip and 808 chip communication anomaly e5
Communication with electron expansion valve box abnormal e7
Wire controllers communicate with interior control panels
Indoor and offline communication anomaly e9
Water temperature sensor anomaly eb
Remote control receiver internal malfunctioning method (time-light flashing when running indicates interior malfunction)
Timelight flashes one time, fluid tube temperature sensors abnormal
Timelight flashes two times. Air-pipe temperature sensors are abnormal
Timelight flashes three times. Ring temperature sensors are abnormal
Timelights flashed four times
Time light flashes five times
Timelight flashes six times. Indoor chip 846
Timelight flashes eight times, electrostatic expansion valve power plate failure
Timelight flashes 10 times. Indoor jet pg
Timelight flashes 11 times. Fluorine switches or pumps are abnormal
Timelight flashes 12 times, internal eeprom data anomaly
Timelight flashed 13 times, room heat overload
Timelight flashes 14 times. Indoor and cable controllers are off
Note: indoor running light flashes are outdoor malfunctions, no matter how many flashes should be checked and the failure code
Identification of external malfunctions
Exterior frost temperature sensor te circuits with sensors under 20h (open road) or above 1000h (short road) detected for 60 seconds, recoverable
Circum-temperature sensor ta circuits, detection of sensors below 20 h°c or above 1000 h (short circuit) for 60 seconds, recoverable
Inhalation temperature sensor ts circuits, 60-second continuous detection of sensors below 20h (open road) or more than 1,000h (short road) recoverable
Emission temperature sensor td circuits, which are activated by a pressurizer for three minutes in a row of 60 seconds, detect sensors below 20h (open road) or above 1,000h (short road) and recoverable below 80 degrees。
The external condenser's central temperature sensor, which is 60 seconds in a row, detects a sensor below 20h (open road) or more than 1,000 h (short road)。
Summary: in the section above, a presentation was made on some of the developments that may have occurred in the event of a malfunction in hal central air conditioning. In general, our air conditioning screens show some of the letters that are relevant to remind us which part of the air conditioning is in question. But in addition to this way, we can judge by some of the outside air conditioners in the flashing light. But for non-professionals, they don't advise you to do it yourself。
