4.1 Power On/Off
When the controller is working normally, press and hold the [SET Key], [Up Arrow], and [Down Arrow] keys simultaneously for 3 seconds to enter the power-off state. All displays and outputs will turn off. To turn on, press and hold the [SET Key], [Up Arrow], and [Down Arrow] keys simultaneously for 1 second from the power-off state to enter normal measuring mode.
4.2 Enquiry Differential Value
When the controller is working normally, briefly press the [Up Arrow] key once; the humidification differential (HD) will be displayed. Briefly press the [Down Arrow] key once; the dehumidification differential (DD) will be displayed. After two seconds, the display will return to the normal humidity mode.
4.3 Enquiry Measuring Humidity
Press the [Up Arrow] and [Down Arrow] keys simultaneously. The current humidity value will be displayed on the PV screen. Release the keys after 2 seconds to return to the normal display mode.
4.4 How to Set Parameters
When the controller is working normally, press and hold the [SET Key] for 3 seconds to enter parameter setting mode. The PV screen will display the first menu code "HS", and the SV screen will display the corresponding setting value. Press the [SET Key] to page down through the menu. The code will be displayed, and then use the [Up Arrow] or [Down Arrow] keys to change the current parameter value. After finishing settings, press and hold the [SET Key] for 3 seconds to save the parameter setting value and return to the normal humidity display mode. If there is no operation for 10 seconds during setting, the system will automatically quit the menu and return to normal display without saving modifications.
4.5 Setup Flow Chart
To enter parameter setup mode, press and hold the [SET Key] for over 3 seconds.
- HS (Humidity Set Value): Default 50%RH. Press
[SET Key]to proceed. - HD (Humidification Differential Value): Default 5%RH. Press
[SET Key]to proceed. - DD (Dehumidification Differential Value): Default 5%RH. Press
[SET Key]to proceed. - AH (Alarm High Humidity Set Value): Default 99%RH. Press
[SET Key]to proceed. - AL (Alarm Low Humidity Set Value): Default 0%RH. Press
[SET Key]to proceed. - PT (Delay Protection Value): Default 1 minute. Press
[SET Key]to proceed. - CA (Humidity Calibration): Default 0%. Press and hold
[SET Key]for 3 seconds to save and return to 'Working normally' mode.

5.1 Humidity Control Range Setting (HS, HD, DD)
When the controller is working normally, the LED displays the current measured humidity. It then automatically starts recognizing and translating humidifying and dehumidifying actions.
When measured humidity PV ≥ HS (Humidity Set Value) + DD (Dehumidification Differential Value), the controller enters dehumidification mode. The dehumidification indicator lamp turns on, and the dehumidification relay activates. If the dehumidification indicator light flickers, the equipment is in delay protection status. When the measured humidity PV ≤ HS (Humidity Set Value), the dehumidification indicator lamp turns off, and the dehumidification relay stops working.
When the measured humidity PV ≤ HS (Humidity Set Value) – HD (Humidification Differential Value), the controller enters humidification mode. The humidification indicator lamp turns on, and the humidification relay activates. When the measured humidity PV ≥ HS (Humidity Set Value), the humidification indicator lamp turns off, and the humidification relay stops working.
5.2 Alarm High/Low Limit Setting (AH, AL)
When the measured humidity PV ≥ AH (Alarm High Humidity Set Value) or PV ≤ AL (Alarm Low Humidity Set Value), an alarm sounds ("BI-BI-BIII"). The current value, AH, or AL will display on the PV screen. The alarm sound can be stopped by pressing any key, but the alarm status will not change until the measured humidity returns to the normal range.
5.3 Compressor Delay (PT)
In dehumidification mode, after power on, if the measured humidity PV ≥ HS (Humidity Set Value) + DD (Dehumidification Differential Value), the equipment will not start dehumidification immediately but will wait for a delay time.
If the time interval between two dehumidification operations (or from power on to dehumidify) is longer than the preset delay, the equipment starts dehumidification immediately. If the time interval is less than the preset delay, the equipment will not start dehumidification until the preset delay is satisfied.
The delay time is calculated right after the moment dehumidification stops.
5.4 Humidity Calibration (CA)
When there is a deviation between the measured humidity and the actual humidity, use the humidity calibration function to align them. The corrected humidity is equal to the humidity before calibration plus the corrected value (which can be positive, zero, or negative).
6. Error Description
Sensor fault alarm: If the humidity sensor is short-circuited or open-circuited, the controller will enter sensor fault mode and cancel all actions. The buzzer will sound, and the LED will display "ER". The buzzer alarm can be dismissed by pressing any key. After the fault is resolved, the system will return to normal working mode.
