Xuzhou Sheng Erda Refrigeration Electrical Services Ltd. 5. auxiliary heating function fails. If the electric auxiliary heating control circuit occurs or electric auxiliary heating equipment failure, does not work, at relatively low ambient temperatures, it will lead to lack of air conditioning heat capacity, even in the harsh environment of air conditioning and heating completely. 6. For an electric heat pump air conditioning, if there is high ambient temperature (above 5 ℃) heating normal and low ambient temperature (below 0 ℃) insufficient heating capacity or not heating, electric auxiliary heating should be suspected The control circuit or electric auxiliary heating equipment failure, maintenance should focus on checking these two parts. Xuzhou Sheng Erda Refrigeration Electrical Services Limited ☆ sleep comfortably run a way to adapt to human sleep (SLEEP) mode of operation. After the summer nights sleep, if the air conditioner has been turned on, the indoor temperature is too low will cause people colds, from human physiology point of view, I hope at different stages of sleep have different ambient temperature, which can meet the sleep mode operation kinds of needs. After setting the sleep mode in the US state of refrigeration, air conditioning repair phone, note the time of the controller set temperature, one hour after the air conditioning repair, the set temperature will be in the original basis of the set temperature rises high a degree, and a new set the temperature control of the compressor open to stop the old air conditioning maintenance, another 1 hour, and then set the temperature rises one degree. Thus throughout the sleep process, the ambient temperature rising, depending on the model, this temperature increase in the range of about 2 to 3 degrees. Also in the heating operation, they can press the sleep mode of thinking set central air conditioning repair acquisitions continue to lower the ambient temperature, the range of about 2 to 5 degrees, to prevent overheating. Central air conditioning maintenance acquisitions, Sheng Erda refrigeration (certified), air conditioning maintenance provided by Xuzhou 圣尔达 Refrigeration Electrical Services Limited.
