Frequently Asked Questions:

1. When the temperature and humidity controller displays abnormal temperature;

Check steps:

1. Check whether the over-temperature protector of the control panel is set at the position of 150℃;

2. Check whether the circulating motor in the equipment room is damaged or not running;

3. Check whether the solid-state relay in the temperature part is burned out and short-circuited

If the heater is not burned out, use a three-meter meter AC voltage range, the voltage range is turned to the 600 volt position, place the red and black rods on the AC side of the solid state relay marked with the wire number T, and place the temperature part The temperature setting value is set to 0℃. At this time, the indicator light of the solid state relay in the temperature part will not light up. If the measured voltage value does not change, it remains below 10V, which means that the solid state relay burns out and shows a short circuit state.

Solution:

1. Turn the panel over-temperature protector to the position of 150℃, or add 30℃ to the use temperature;

2. Notify the manufacturer's customer service and maintenance department to replace the circulating motor;

3. Replace the solid-state relay in the temperature part (the solid-state relay marked with the line number T), or notify the after-sales service for repair.

Second, when the temperature and humidity controller displays abnormal humidity;

Check steps:

1. Check whether the under-temperature and over-temperature protector in the control equipment room is set at the position of 150℃

2. Check whether the pipeline is too dirty in the equipment room, causing the water flow to be irregular;

3.Check whether there is water in the upper water tank, if there is no water, then check whether there is water in the lower water tank;

4. Check whether the solid state relay of the humidity part is burned out and short-circuited: if the heater is not burned out, use the AC voltage file of the three-use meter, the voltage gear is turned to the position of 600 volts, and the red and black bars are placed on the line number marked H On both sides of the solid state relay, set the humidity setting value of the humidity part to 0%. At this time, the indicator light of the solid state relay of the humidity part will not light up.If the measured voltage value does not change, maintain it at 10V The following represents that the solid state relay is burned and short-circuited. Or first set the humidity part set value to 0%, and then see if the humidification bucket in the machine room is boiling.

Solution:

1. Turn the under-temperature and over-temperature protector to the position of 150℃;

2. First turn off the main power at the rear of the machine, and then open the drain valve below the humidifier barrel to a position parallel to the pipeline.When the water with the water tank is exhausted, use the wrench to open the humidifier barrel and turn the inside Due to the long-term removal of humidity scale, then pull out the silicone tube, scrub in water, after maintenance, install it in the opposite direction according to the way of removal.After the device is completed, the drain valve below the humidification barrel needs to be closed to the pipe Vertical position, and then turn on the main power at the rear of the machine;

3. There is no water in the water tank. Add water to the water tank to solve it. If there is no water in the upper water tank, and there is water in the lower water tank, the water pump motor for the lower water tank is broken, and notify the environmental service company customer service department to come to the door for repair;

4. Replace the solid state relay in the humidity part (the solid state relay marked with the line number H), or notify the after-sales service for maintenance.

3. When the temperature and humidity controller displays abnormal pressure;

Check steps:

1.Check the location of the equipment, whether there is a position more than 30 cm away from the wall;

2. Whether the surroundings are confined spaces.

Solution:

1. Maintain a position of more than 30 cm around the machine, because poor heat dissipation will cause the high pressure side of the compressor to be too high;

2. If the surrounding is a closed space, it will cause a temperature rise in the environment and the pressure on the high-pressure side of the compressor will be too high, so keep the surroundings ventilated.

4. When the temperature and humidity controller displays the abnormal condition of the compressor;

Check steps:

1.Check the location of the equipment, whether there is a position more than 30 cm away from the wall;

2. Whether the surroundings are confined spaces.

Solution:

1. Maintain a position of more than 30 cm around the machine, because the poor heat dissipation will cause the compressor operating current to rise, which will cause the overcurrent protector to operate;

2. If the surrounding is a closed space, it will cause a temperature rise in the environment, it will also cause the compressor operating current to rise, and cause the overcurrent protector (heat accumulation relay) to operate. So keep the surroundings ventilated;

3. After all the above problems have been solved, put the overcurrent protector (heat accumulation relay) under the three electromagnetic switches in the machine room. When the reset button is pressed down, there is a click, which means that the controlled compressor is overloaded, but it is also reset at this time, and the current setting value is transferred to 1.25 times the rated current of the compressor.

5. After the temperature and humidity controller is in operation, the actual humidity value is always displayed at 100%;

Check steps:

1. The air in the box is very dry: first check whether there is water in the sink part of the wet and dry ball fixing seat; 2). check the dry and wet ball fixing seat inside the test box, hanging on the wet ball sensor part Whether the wet ball gauze is wet in the sensor part;

2. The air in the box is very humid (the humidity may not reach 100%, but it is always high): first set the humidity part to 0%, and then see if the water in the humidification barrel in the machine room is boiling.

Solution:

1. The air in the box is very dry: 1). If there is no water, adjust the water level cup in the equipment room, whichever is above, or check whether the pipeline between the water level cup and the wet and dry ball fixing seat is blocked. Use cloth after adjustment. , Drain the water to make sure the water will go in all the time. 2). If it is not wet, replace the gauze. (It is recommended to change the gauze once a month) If you often do high temperature and high humidity conditions, you need to change more times. If you only do temperature conditions, you can take out the gauze and extend the life. After taking out, it can be soaked in alcohol, which has extended its life;

2.The air in the box is very humid (the humidity may not reach 100%, but it is always high): If there is boiling, replace the solid state relay of the humidity part (the solid state relay marked with the line number H) or notify the after-sales Come home for repairs.

Sixth, after the temperature and humidity controller is running, the actual value of humidity has not reached the set value, and the actual value of humidity is much lower than the set value of humidity;

Check steps:

1. Check whether the solid state relay of the humidity part is burnt and broken: if the heater is not burned, use the AC voltage file of the power meter, the voltage gear is turned to the 600 volt position, and the red and black bars are placed on the line marked with H On both sides of a solid state relay, set the humidity setting value of the temperature part to 100%.At this time, the indicator light of the solid state relay of the humidity part will light up.If the measured voltage value does not change, maintain it at 220V or 380V. It means that the solid state relay is burned and shows an open state;

2. Check whether the fuse is burnt out;

3. Check whether the humidification barrel heater is burnt: cut the two lines of the humidification barrel heater, use the ohm file of the three-meter meter, and measure the resistance value. If the resistance is infinite, it means the heater is burnt out.

Solution:

1.Replace the solid state relay in the humidity part (the solid state relay marked with the line number H), or notify the after-sales service to repair it;

2. Replace the fuse of the same specification;

3. Inform the purchaser to send the humidifier heater, or notify the after-sales service for maintenance.
