Precision temperature controller for reliable, automatic climate management Key benefits and why you need it Maintain stable, exact temperatures to protect sensitive processes and living systems. The controller holds temperatures from -50°C to 99°C with ±0.1°C accuracy and 0.1°C display resolution, reducing fluctuations that harm fermentation, delicate animals, plants, or electronics. Automatic heating and cooling without manual switching. The unit detects whether conditions are above or below your setpoint and switches to heating or cooling accordingly, simplifying setup and reducing intervention. Built-in protections extend equipment life and reduce risk. Adjustable compressor delay (1–10 minutes) prevents short-cycling; overload protection via a 10A/220V relay helps safeguard connected devices. What it does (functions and performance) Precise sensing: NTC sensor probe delivers accurate temperature feedback used by the controller to maintain tight control. Clear readout: LCD displays temperature with 0.1°C resolution and a Celsius/Fahrenheit switch for preferred units. Smart dual-mode operation: Automatically engages heating mode when below the setpoint and cooling mode when above it—ideal for continuous, unattended control. Compatibility and safe operation Designed to work with standard on/off heating and cooling equipment that operate within the controller’s relay capacity (10A/220V). Use with heaters, refrigerators, chillers, fans, or similar devices controlled by a relay. Adjustable compressor delay (1–10 minutes) reduces stress on compressors and prevents rapid on/off cycling. Overload protection helps prevent damage to connected appliances. Practical use scenarios Homebrewing: Maintain exact fermentation temperature to improve yeast performance and consistency in beer or wine. Reptile terrariums and pet habitats: Keep stable day/night temperatures for animal health and behavior. Aquariums and hydroponics: Control chillers and heaters to protect aquatic life and optimize plant growth.
