Functionality and Operation:
1. Humidity Control Settings:

• Press the SET button once to enter humidity control settings. After 3 seconds, the display will flash, showing the code HC.
• Use the ▲ or ▼ buttons to cycle through parameter codes: HC-CP-PU-CA-HP.
• Press SET to enter a specific code, then adjust values using ▲ or ▼. The system will save changes automatically after 5 seconds.

2. Temperature Control Settings:

• Press the SET button twice to enter temperature control settings. After 3 seconds, the display will flash, showing the code HC.
• Use the ▲ or ▼ buttons to cycle through parameter codes: HC-CP-PU-CA-HP.
• Press SET to enter a specific code, then adjust values using ▲ or ▼. The system will save changes automatically after 5 seconds.

3. Modes of Operation:

• Dehumidification Mode (C): Set the humidity control value (e.g., 50% RH) and return difference (e.g., 5%). Relay starts output when humidity exceeds the set value and stops when humidity drops below the set value minus the return difference.
• Humidification Mode (H): Set the humidity control value (e.g., 50% RH) and return difference (e.g., 5%). Relay starts output when humidity falls below the set value minus the return difference and stops when humidity reaches the set value.
• Heating Mode (H): Set the heating temperature (e.g., 35°C) and return difference (e.g., 2°C). Relay starts output when the temperature drops below the set value minus the return difference and stops when the temperature reaches the set value.
• Cooling Mode (C): Set the cooling temperature (e.g., 35°C) and return difference (e.g., 2°C). Relay starts output when the temperature exceeds the set value plus the return difference and stops when the temperature drops to the set value.

4. Alarm Functions:

• Humidity Alarms:
  • Upper Limit Alarm (HP): Displays “-H-” when humidity exceeds the upper limit. Automatically resets when humidity drops below the alarm threshold.
  • Lower Limit Alarm (LS): Displays “-L-” when humidity falls below the lower limit. Automatically resets when humidity rises above the alarm threshold.
• Temperature Alarms:
  • Upper Limit Alarm (HP): Displays “HHH” when temperature exceeds the upper limit. Automatically resets when temperature drops below the alarm threshold.
  • Lower Limit Alarm (LS): Displays “LLL” when temperature falls below the lower limit. Automatically resets when temperature rises above the alarm threshold.

5. Factory Reset:

• Press and hold the Left, Up, and Down buttons simultaneously until the screen displays “888.” The system will reset to factory settings.

Applications:

• 🌱 Agriculture: Greenhouses, seedling cultivation, and crop storage.
• 💧 Aquariums: Maintaining optimal water temperature and humidity levels for aquatic life.
• ❄️ Refrigeration: Precision cooling for food storage and specialized applications.
• 🍺 Brewing & Fermentation: Monitoring and controlling fermentation temperatures for consistent results.
• 🏠 Home Use: Dehumidifiers, humidifiers, and HVAC systems.

Package Includes:

• 1x Advanced Digital Temperature & Humidity Controller
• 1x NTC Temperature Probe (1.5m cable length)
• 1x Resistance-Type Humidity Sensor (1.5m cable length)
• 1x User Manual

Important Notes:

• ⚠️ Operating Range: Ensure the controller is used within its specified temperature (-20°C to 80°C) and humidity (1%RH–99%RH) ranges for optimal performance.
• ⚡ Load Capacity: Do not exceed the maximum load capacity of 10A/AC220V to prevent overloading the device.
• 🔍 Sensor Placement: Position sensors carefully to ensure accurate readings, avoiding direct exposure to water, extreme heat, or physical damage.
• 🛡️ Safety First: Always check connections and ensure proper wiring to prevent electrical hazards.
