Key benefits Reliable temperature control for household appliances: precisely manage heaters, coolers and other devices up to 16 A / 3680 W to protect equipment and keep processes stable. Easy to read and use in any light: a backlit LCD shows current and set temperatures and gives fast access to calibration, memory, reset and lock-screen protection. Flexible scheduling and automatic mode switching: built-in timers and automatic heating/cooling logic let the controller run unattended according to your needs. What it does (core functions) Backlit LCD display: clearly shows current temperature and setpoints even in low light. Menu options include calibration, memory recall, reset and lock-screen protection for safe operation. Automatic heating or cooling control: stepless control based on Start and Stop temperature settings. If Start temperature > Stop temperature the cooling mode is activated; if Start temperature < Stop temperature the heating mode is activated. Wide temperature range and accurate regulation: temperature control range from −40 °C to 120 °C with control accuracy of approximately ±1%. Electrical compatibility and performance: supports loads up to 16 A (3680 W). Timing and scheduling: device includes timing capability (timing approx. max 10 minutes) and advanced timer modes — cycle timer, countdown ON, countdown OFF, and countdown ON+OFF — with time range 0:00 to 99:59 (hours:minutes). Key specifications (concise) Temperature range: −40 °C to 120 °C Load capacity: up to 16 A / 3680 W Temperature control accuracy: ≈ ±1% Display: backlit LCD with calibration, memory, reset, lock-screen functions Timer modes: cycle, countdown ON, countdown OFF, countdown ON+OFF; timer range 0:00–99:59 Heating/Cooling logic: automatic mode selection based on Start vs. Stop temperature Practical applications (how customers use it) Aquarium and pond control: keep water heaters or chillers within narrow ranges to protect fish and aquatic life. Home fermentation, brewing or fermentation cabinets: maintain consistent temperatures for yeast and cultures with automatic switching between heating and cooling devices. Terrariums, seedling propagation and small greenhouses: maintain stable habitat temperatures for reptiles, seedlings or sensitive plants. General appliance thermostat: control space heaters, fans, circulation pumps or refrigeration units where accurate temperature control and timed cycles are required. Why customers choose this controller Precise, wide-range control suitable for many household and hobby applications. Clear, backlit display with usability features (calibration, memory, reset, lock) that reduce setup time and prevent accidental changes. Flexible automatic modes and long-range timers let you automate temperature routines reliably. Rated for common household loads (16 A / 3680 W), so it works with most standard heaters, coolers and pumps. Notes on compatibility and safe use Designed to control household electrical appliances within the stated load rating (16 A / 3680 W). Do not exceed the rated current or power. Follow applicable local electrical codes when wiring or installing the controller. Use appropriate wiring, fuses or circuit protection as required. Controls and indicators Backlit LCD for status and setpoint display Menu options for calibration, memory, reset and lock-screen protection Timer configuration for cycle and countdown modes (0:00–99:59) This digital temperature controller delivers clear readout, automatic heating/cooling switching, a wide and accurate temperature range, and flexible timers — ideal for stable, repeatable temperature management of household appliances and hobby systems.
