Opsætningsinstruktioner

Before connecting the device, ensure that the power supply is disconnected. Incorrect wiring can cause damage to the unit or connected equipment.

Ledningsføring:

1. Strømforsyning: Connect the AC110-220V power supply to the designated input terminals on the back of the controller. Refer to the wiring diagram on the device casing for precise connections.
2. Sensortilslutning: Plug the soil moisture sensor cable(s) into the sensor port(s). Ensure a secure connection.
3. Tilslutning af outputenhed: Connect the device(s) you wish to control (e.g., water pump, humidifier) to the "Exportation" output terminals. The relay supports up to 10A and an output power of 1500W. Ensure the connected device's power requirements do not exceed these limits.

Sensorplacering:

Insert the soil moisture sensor(s) into the soil at the desired depth and location for monitoring. Ensure the sensor probes are fully embedded for accurate readings.

Once all connections are made, you may connect the controller to the main power supply.

Betjeningsvejledning

Tænd/sluk:

Tryk på Sluk nøgle (power symbol) to turn the device on or off.

Viewing Current Humidity:

Upon powering on, the large screen display will show the current humidity percentage detected by the sensor(s).

Setting Humidity Parameters:

1. Tryk og hold på Set Key (S) for a few seconds to enter the parameter setting mode. The display will typically flash or show a parameter code.
2. Brug Up Key (▲) og Down Key (▼) to navigate through different parameters (e.g., start humidity, stop humidity, calibration).
3. Når den ønskede parameter er valgt, skal du trykke på Set Key (S) again to modify its value.
4. Brug Up Key (▲) og Down Key (▼) for at justere værdien.
5. Tryk på Set Key (S) for at bekræfte den nye værdi.
6. To exit the setting mode, press the Sluk nøgle or wait for the device to automatically exit after a period of inactivity.

Note: For the STC-3030 model with dual-channel control, you can set independent humidity values for each output channel. Refer to the specific wiring diagram and display indicators for channel selection during parameter setting.

Automatisk kontrol:

Once the humidity parameters are set, the controller will automatically activate or deactivate the connected output device(s) to maintain the desired humidity range. The "Output light" will illuminate when the output is active.
