Advanced Digital Temperature & Humidity Controller https://herosmartele.com/wp-content/uploads/2025/04/Digital-Temperature-Humidity-Controller.mp4 �� Product Overview: This advanced digital controller is designed for precise temperature and humidity control in a variety of applications, including industrial, agricultural, and residential environments. With its dual functionality for heating, cooling, humidification, and dehumidification, it ensures optimal environmental conditions while offering user-friendly operation and reliable performance. Key Features: ��️ Dual Temperature & Humidity Control: Supports both temperature (heating/cooling) and humidity (humidifying/dehumidifying) control modes. �� Wide Control Range: Humidity: 1%RH–99%RH Temperature: -20°C to 80°C ⚡ Load Power: 10A/AC220V with relay output for compatibility with various devices. ⚙️ Precision Sensors: Temperature Sensor: NTC precision ±1°C Humidity Sensor: Resistance-type sensor precision ±3%RH �� Permanent Memory: Retains all parameters even after power failure, ensuring uninterrupted operation upon power restoration. ⚠️ Alarm System: Includes upper and lower limit alarms for both temperature and humidity, with automatic recovery when conditions normalize. ⏳ Delay Start Function: Prevents frequent relay switching by introducing a user-defined delay between operations. �� Compact Design: Dimensions of 90x60x26.5mm (LxWxH), making it easy to install in tight spaces. �� Versatile Power Supply Options: DC12V, DC24V, or AC220V (selectable). �� Probe Line Length: Standard 1.5m cable length for flexible sensor placement. Technical Specifications: ��️ Temperature Control Range: -20°C to 80°C �� Humidity Control Range: 1%RH–99%RH �� Measurement Accuracy: Temperature: ±1°C Humidity: ±3%RH (at 25°C ambient temperature) ⚡ Load Power: 10A/AC220V �� Output Type: Relay output (probe type) �� Dimensions: 90x60x26.5mm (LxWxH) ⏱️ Working Environment: Temperature: 0°C–55°C Humidity: ≤90%RH (no condensation) 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.
