High-Humidity Temperature & Humidity Contr...

STC-3028 High-Humidity Temperature & Humidity Controller (220V AC) – Ideal for Mushroom Cultivation Say goodbye to unreliable humidity controllers! The STC-3028 is a robust, dual-relay system designed for high-humidity environments like mushroom cultivation, hydroponics, and reptile enclosures. Unlike budget controllers with DHT11 sensors that fail above 80% RH, this unit features a professional-grade Sensirion SHT20 sensor, rated for 0-100% RH with ±3% accuracy at extremes, ensuring stable performance in humid grow rooms. Tested for durability in South African conditions, it’s the go-to choice for serious cultivators. Key Features ��️ Dual Relay Control: Independently manage heating/cooling and humidifying/dehumidifying devices (10A max per channel). �� High-Humidity SHT20 Sensor: Industrial-grade, handles 0-100% RH with minimal drift, perfect for mushroom fruiting chambers (85-95% RH). �� 220V AC Compatibility: Wired directly into standard South African outlets. �� Clear LCD Display: Real-time temperature and humidity readings with intuitive button controls. �� Flexible Settings: Customize target ranges, hysteresis, and delay times for precise environmental control. �� Power-Loss Memory: Retains settings after outages, ensuring uninterrupted operation. Applications Mushroom cultivation (incubation and fruiting stages) Hydroponics and greenhouse gardening Reptile terrariums and vivariums Climate-controlled storage for sensitive goods Specifications Power Supply: 220V AC, 50/60Hz Temperature Range: -20°C to 80°C (±0.5°C accuracy) Humidity Range: 0-100% RH (±3% accuracy at 80-100% RH) Sensor Type: Sensirion SHT20 (capacitive, replaceable, 1m probe) Relay Output: 10A max per channel (dual relays for temp & humidity) Dimensions: 85mm x 75mm x 35mm Weight: ~200g What’s in the Box STC-3028 Controller Unit SHT20 High-Humidity Sensor Probe (pre-installed) Mounting Accessories Why Choose the STC-3028? Standard controllers with DHT11 or similar sensors falter in high-humidity environments, drifting or failing within weeks. The STC-3028’s SHT20 sensor is engineered for precision and longevity, delivering reliable readings even at 90-100% RH—ideal for South African mushroom growers aiming for healthy mycelium and abundant fruiting. Its rugged design and easy calibration (via UP DOWN buttons) ensure hassle-free operation. Note: The sensor probe handles high humidity, but the controller unit itself is not waterproof. Install it outside high-humidity zones (e.g., outside your grow tent) to protect electronics. STC-3028 Mounting The STC-3028 is a digital temperature and humidity controller that is designed for embedded panel mounting. This means you install it into an opening you cut into a surface, such as the wall of an incubator or equipment enclosure. Step 1: Create the panel cut-out Measure and mark the rectangular opening for the controller. Cutout dimensions: 71 mm wide by 29 mm high. Front panel dimensions: The front panel of the controller is slightly larger, measuring 75 mm wide by 34.5 mm high, to cover the cut-out. Step 2: Insert and secure the controller Push the STC-3028 controller into the cut-out from the front side of the panel. The controller will have integrated clips or “ears” on its sides. As you insert it, these clips will compress and then spring back out behind the panel, holding the unit firmly in place. Ensure the controller is flush with the panel before you begin wiring. Step 3: Wire the connections Before performing any wiring, always disconnect the power to prevent electric shock. The STC-3028 has terminals for power, sensors, and the output relays for your heating/cooling and humidifying/dehumidifying devices. Power supply: Connect the power source to the designated terminals. Be sure to match the voltage to your specific STC-3028 model (e.g., 110-220VAC, 12VDC, or 24VDC). Sensor: Connect the integrated temperature and humidity sensor to its designated terminals. Outputs: Wire your external devices (such as a heater, fan, or humidifier) to the output relay terminals. The relays act as switches to control your equipment. Important safety precautions Disconnect power: Always turn off the power supply before handling any electrical connections. Keep wires separate: Maintain a proper distance between the low-voltage sensor wire and the high-voltage power wire to prevent interference. Professional installation: If you are not familiar with electrical wiring, have the installation performed by a qualified electrician or technician.
