Answer：
(1) Firstly, you can check if the outlet temperature matches the actual temperature. If it does not match, you need to replace the water temperature probe;
(2) If the outlet temperature matches the actual temperature, it is necessary to check whether the temperature value of the water tank matches the actual value (if the water tank temperature control machine is working); Then check and clean the pipeline filter, check whether the pipeline valve is damaged or not, check whether the circulating pump meets the unit flow requirements, whether it operates normally, and so on.（If you have any questions, please contact the after-sales service hotline: +86-400-100-1661）

Answer：
(1) Firstly, you can check whether the exhaust temperature value of the unit matches the actual temperature. If it does not match, you need to replace the exhaust temperature probe;
(2) If the exhaust temperature value matches the actual temperature, it is necessary to check the operation of the unit and check if the cooling fins of the meter are blocked? Is there a lack of fluorine in the unit? Is there any gas leakage in the compressor? Is there any blockage in the refrigerant pipeline?（If you have any questions, please contact the after-sales service hotline: +86-400-100-1661）

Answer：
(1) When the local ambient temperature is lower than the antifreeze setting of the air energy unit, the unit will automatically start the antifreeze cycle to prevent damage to the water pump, pipelines, and internal parts of the unit. Especially if the air can prevent freezing protection is not activated, and the water pump is frozen again, it is very easy for the equipment to burn out.
(2) At this point, you can first check whether the ambient temperature value matches the actual value. If it matches, the antifreeze protection is normal. If it does not match, you need to replace the probe.（If you have any questions, please contact the after-sales service hotline: +86-400-100-1661）

Answer：
(1) This type of malfunction is generally rare, but in cold winter, if the unit experiences fluorine leakage or other reasons leading to system problems and the machine is not running, at this time, if the local environment is below 10 ℃, the unit is likely to report an exhaust sensor malfunction.
(2) You can first check whether the connector of the sensor probe on the motherboard side is secure;
(3) Check again if the exhaust temperature matches the actual temperature. If it does not match, check the wiring of the probe for any damage, and then replace the exhaust probe;
(4) If the exhaust temperature matches the actual temperature, it is necessary to check whether the compressor of the unit is in normal working condition;
(5) If none of the above situations are true, at this point, it is necessary to check if there are any issues with the motherboard;
