Wait for 5- 10 minutes when heating in early winter, and adjust the air conditioner from cold to hot. You turn on the hotkey and see that the air conditioning light on it is gone. If you work in an air conditioner. After waiting for 15 minutes, the air conditioner didn't respond, so I called Changhong after-sales and asked them what the situation was.
Changhong air conditioner doesn't heat up no matter how it is adjusted.
When the air conditioner heats, there will be a buffer time, and the fan will not be turned on immediately to prevent the cold air from blowing out. This time is about 3-5 minutes. Because now when heating, you need to open the four-way valve to make it reverse. In another case, when the outdoor temperature is too low, the temperature of the air conditioning coil can't reach the set value, so the air conditioner won't start and the waiting time will be longer. This is normal. If the startup time is too long, please contact the manufacturer.
How to heat Changhong air conditioner?
Generally, when heating is used for the first time, the preheating time may be longer, but it generally does not exceed 10 minute. If hot air is not sent into the machine for more than 10 minutes, it may be a fault.
Heating method:
1, after turning on Changhong air conditioner, it can be clearly seen from the remote control of Changhong air conditioner that the initial state of Changhong air conditioner is automatic;
2. If you want Changhong air conditioning to heat, you need to click the "Mode" button first, and then adjust the steps of refrigeration-dehumidification-air supply-heating. Icons in the shape of snowflakes indicate cooling, raindrops indicate dehumidification, fan blades indicate air supply, and sun icons indicate heating.
3. Changhong Air Conditioning displays the heating status of Changhong Air Conditioning in the shape of a sun icon. Users can adjust the temperature of Changhong air conditioner. Changhong air conditioning generally adjusts Changhong air conditioning to the highest temperature; Changhong variable frequency Changhong air conditioner can realize rapid cooling or heating in the process of cooling or heating, effectively shortening the heating or cooling time. Extended information: Core technology: low-temperature heat pump technology: Dr. R&D team of Changhong Intelligent Central Air Conditioning, after years of painstaking research, has widely applied the patented technology of enhanced steam jet scroll compressor to water systems and series of remote machine systems. , and successfully launched a series of air-cooled modular units and wind turbines. , normal heating operation can be started at -20℃.
"Wind Cube" technology: The silent air duct technology of "Wind Cube" greatly reduces the running noise of air conditioner, makes the air smoother, reduces the return air duct with energy loss, improves the heat exchange speed by 30% and improves the energy efficiency. As an inevitable trend of the rapid development of today's society, intelligence has been involved in all aspects of modern people's work and life more and more deeply. Changhong intelligent central air conditioning will change the original profit model of air conditioning "hardware" to "hardware+content+service", and 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 should not only realize simple cooling and heating functions, but also improve the indoor air environment. The air filtration room adopts high-pressure ionization technology and nano-cold catalyst filtration, which can effectively remove all kinds of dust and smoke in the air, electrolyze a large number of negative oxygen ions and reduce the indoor fresh air volume. VISA series hanging machines and cabinets adopt seven health technologies to protect the health of family members.
Whether it is one air conditioner, one multi-frequency air conditioner, multi-frequency intelligent variable frequency air conditioner, air-cooled modular unit, water-cooled screw unit and water source heat pump unit, the throttling principle of domestic and commercial heat pump water heaters may be different, but the same theme is energy saving.

Changhong air conditioner can cool but not heat.
How about cooling in summer? Ok, mode, temperature, power supply, wait for normal? Normal. How long does it take to start the machine without heating? Fault subsystem fault and control fault. You are more specific.
