When there is something wrong with the air conditioner, we must strictly follow the scientific procedures. Don't act blindly and disassemble at will when the situation is unknown, the fault is unknown and there are countless things in mind.
Such consequences will often expand the existing faults, increase operating costs, shorten the normal service life of equipment, and lead to premature scrapping of equipment.
Introduction of Changhong Air Conditioning Fault Code;
F6 The thermistor of outdoor unit is broken or damaged;
H 1 compressor motor overload;
H2 compressor motor locking;
H3 compressor current detection is abnormal;
H6 low-voltage switch action (KFR-7 1LW/M None);
H7 The line or pipe connecting the indoor unit and the outdoor unit is incorrectly connected.
Extended data:
Changhong, founded in 1958, has become a comprehensive multinational enterprise group integrating military industry, consumer electronics, R&D and core device manufacturing, and is moving towards a globally competitive information appliance content and service provider.
core technology
Ultra-low temperature heat pump technology: After years of painstaking research, the research and development team of Dr. Changhong Intelligent Central Air Conditioning has widely applied the patented technology of enhanced steam jet scroll compressor to water machine systems and unit machine systems, and successfully launched ultra-low temperature series air-cooled modular units and air duct units, which can normally start heating operation at -20℃.
"Wind Cube" technology: Without changing the air volume and wind speed, the "Wind Cube" silent duct technology greatly reduces the operating noise of the air conditioner, makes the air outlet smoother, reduces the energy loss of the return air in the duct, improves the heat exchange speed by 30%, and has higher energy efficiency.
Core characteristics
Intelligent, healthy and energy saving
As an inevitable trend of the rapid development of today's society, intelligence has penetrated into all aspects of modern people's work and life. Changhong Intelligent Central Air Conditioning has changed the profit model of the original air conditioner from "hardware" to "hardware+content+service". Breakthrough applications such as video monitoring, voice control and automatic air quality monitoring will become a highlight of Changhong intelligent central air conditioning.
Changhong intelligent central air conditioning requires not only the simple function of cooling and heating, but also the improvement of indoor air environment. The air purification chamber adopts high-pressure ionization technology and nano-cold catalyst filter screen, which can effectively remove all kinds of dust and smoke in the air, electrolyze a large number of negative oxygen ions and reduce indoor fresh air.
VISA series uses seven health technologies to ensure the health of family members. Whether it is a one-for-one, multi-frequency air conditioner, multi-intelligent variable-frequency air conditioner, air-cooled modular unit, water-cooled screw unit, water source heat pump unit, or household or commercial heat pump water heater, the throttling principle may be different, but the constant theme is energy saving.
