1.What should I do if the value detected by the main board of the unit exceeds the limit value of the outlet water temperature?
Answer：
(1) First, check if the motherboard cable is not properly connected; Need to check if the probe circuit is damaged, and then check if the circuit connector on the motherboard side is secure;
(2) Check if there is a sensor malfunction. If there is a problem with the sensor itself, you can replace the probe for the outlet water temperature;
(3) Check if there is a problem with the motherboard. If the motherboard is broken, it can also affect the unit's water temperature detection. It is recommended to replace the motherboard.

2.Why can't the motherboard of the unit detect the water inlet temperature?
Answer：
(1) First, check if the motherboard cable is not properly connected; Need to check if the probe circuit is damaged, and then check if the circuit connector on the motherboard side is secure;
(2) Check if there is a sensor malfunction. If there is a problem with the sensor itself, you can replace the probe for the outlet water temperature;
(3) Check if there is a problem with the motherboard. If the motherboard is broken, it can also affect the unit's water temperature detection. It is recommended to replace the motherboard.

3.Why is the outlet temperature of the device different from the set one?
Answer：
(1) Check the probe and its related components;Check if the outlet temperature value matches the actual value, and check if the temperature value of the water tank is equal to the actual value. You can directly touch it with your hand. If the temperature matches, it means that the probe is broken and you can replace it;
(2) Check and clean the pipeline filter;Check if the pipeline valve is damaged and open;If the valve is not damaged and opened, it is necessary to check whether the circulating pump meets the unit flow requirements and operates normally;
(3) If all of the above are normal, you need to check the motherboard to see if there are any issues.

5.What should I do if the water flow is too small to close the water flow switch?
Answer：
(1) If a malfunction occurs after a period of operation, first check and clean the pipeline filter (new machines do not need to be inspected);
(2) Check if the pipeline valves are damaged or open;
(3) Check whether the circulating pump meets the flow requirements of the unit;
(4) Is the water pump connected backwards during the debugging of the new machine;
If all of the above are normal, then the water flow switch itself is faulty. You need to replace the water flow switch or simply short circuit the two wires of the water flow switch on the motherboard. If it is started, it is generally a fault with the water flow switch.

6.The display board shows that the water flow is insufficient and the machine cannot be turned on. What should I do?
Answer：
(1) If a malfunction occurs after a period of operation, first check and clean the pipeline filter (new machines do not need to be inspected);
(2) Check if the pipeline valves are damaged or open;
(3) Check whether the circulating pump meets the flow requirements of the unit;

7.What should I do if the voltage of the unit is below normal and the equipment is under voltage?
Answer：
(1) Check if the wiring is correct. If not, contact specialized after-sales personnel to check if the phase sequence detection on the motherboard is shielded and to detect the phase sequence;
(2) If it is an overvoltage problem, it is necessary to have a professional electrician adjust the transformer voltage to below 420V; The problem of undervoltage requires a professional electrician to adjust the transformer voltage to above 380V;
