User Manal:
1. Connect the power supply and temperature control humidity equipment correctly according to the wiring diagram. Pay attention to the temperature control and humidity control equipment. Do not connect the wrong ones. When connecting the DC12~24V power supply, distinguish the positive and negative poles. AC220V does not divide the zero fire line.
2. Stop the temperature setting
Press the SET button. When the red screen number starts to flash, press the up and down buttons to adjust the desired stop temperature. After setting, wait for 10 seconds without waiting for the system to automatically save the data.
3. Heating or cooling mode setting
Press and hold the up key, when the red screen displays C-0, press the setting button to enter the C-0 mode setting.
The down button switches between blue screens L and H, where L stands for heating and H stands for cooling. (Note: L when you pick up
The temperature-controlled load must be a heating device. When H, the load you connect must be a cooling device. ) set well
Wait 10 seconds, the system automatically saves the data.
4. Temperature difference setting
Press and hold the up key, when the red screen displays C-0, press the up and down keys to switch to the C-1 temperature difference setting, and then press
Set the temperature to the temperature difference setting, then press the up and down keys to adjust the temperature difference you want; set
Wait 10 seconds, the system automatically saves the data. (If the stop temperature is set to 35 ° C, the mode is set to L plus
In the hot mode, the temperature difference is set to 5, and the starting temperature is 35-5=30°C, and the temperature control range is between 30~35°C.
On the contrary, if the mode is set to H cooling mode, the starting temperature is 35+5=40°C, and the temperature control range is
Between 35~40°C)
5. Temperature calibration
Press and hold the up key, when the red screen displays C-0, press the up and down keys to switch to the C-2 temperature correction mode, press the set key to enter the calibration mode, and then press the up and down keys to adjust the difference you want. Value; if the actual temperature is 28 ° C, the probe detection temperature is 28.2 ° C, then the correction difference is set to -0.2; if the detection temperature is low, the correction difference can be increased. Wait 10 seconds after setting, the system automatically saves the data.
Temperature parameter code table:
Code Name Setting range Default parameters
C-0 mode setting L heating H cooling L heating mode
C-1 temperature difference 0.1~50° C 2.0°C
C-2 temperature calibration -10 and 10 °C 0.0 °C
6. Stop the temperature setting
Press the SET button, the red screen number starts to flash, and then press the SET button to switch to the blue screen number.
Blink, press the up and down keys to adjust the desired stop humidity value; do not wait after setting 10
In seconds, the system automatically saves the data.
7. Humidification or dehumidification mode setting
Press and hold the key, when the red screen displays H-0, press the setting button to enter the H-0 mode setting.
The down button performs switching between blue screens L and H, L for humidification and H for dehumidification. (Note: L when you pick up
The humidity control load must be a humidification device. When H is used, the load you are connected to must be a dehumidification device. ) set well
Wait 10 seconds, the system automatically saves the data.
8. Humidity difference setting
Press and hold the key, when the red screen displays H-0, press the up and down keys to switch to the H-1 humidity difference setting, press
Press the setting button to enter the humidity difference setting, press the up and down keys to adjust the setting you want, and set it.
Wait 10 seconds, the system automatically saves the data. (If the stop humidity is set to 50% RH, the mode is set to L plus
In wet mode, the humidity difference is set to 5% RH, the starting humidity is 50-5=45%RH, and the humidity control range is between 45~50%RH. On the contrary, if the mode is set to H dehumidification mode, the starting humidity is 50+. 5=55% RH, the humidity control range is between 50~55% RH)
9. Temperature calibration
Press and hold the key, when the red screen displays H-0, press the up and down keys to switch to the H-2 humidity correction mode.
Press the setting button to enter the calibration mode, press the up and down keys to adjust the setting difference; if the actual humidity is 56% RH,
The probe detects a humidity of 56.2% RH, and the correction difference is set to -0.2;
Low, just adjust the correction difference. Wait 10 seconds after setting, the system automatically saves the data.

Code Name Setting range Default parameters
H-0 mode setting L humidification H dehumidification L humidification mode
H-1 Humidity difference 0.1~50%RH 10%RH
H-2 Humidity Calibration -10 and 10%RH 0.0%RH
10. Restore factory settings
Press and hold the up and down keys for 5 seconds at the same time. When the screen displays 888, the factory will be restored.
