ELITECH STC-1000 Digital Temperature Controller Thermostat with Dual Relay Output

ELITECH STC-1000 Digital Temperature Controller Thermostat in Sri Lanka

Dual Relay Heating and Cooling Thermostat with NTC Sensor

The ELITECH STC-1000 Digital Temperature Controller Thermostat is a compact, panel-mount dual relay thermostat engineered for precise temperature regulation across refrigeration, fermentation, aquarium, incubation, and HVAC applications. With independent heating and cooling relay outputs, a wide measurement range of -50°C to +99°C, and a high-accuracy NTC sensor, the STC-1000 gives technicians and hobbyists alike reliable, fully automatic temperature management in a rugged, cost-effective unit available in Sri Lanka.

The STC-1000 operates on a simple setpoint-plus-differential logic: when the measured temperature rises above the setpoint by the user-defined differential, the cooling relay activates; when it drops below the setpoint, the heating relay activates. This intuitive control logic makes it ideal for homebrewers managing fermentation chambers, aquarists maintaining stable tank temperatures, and engineers building custom temperature-controlled enclosures — with no complex programming required.

Key Features

Independent Dual Relay Outputs: Separate heating and cooling relay channels allow the STC-1000 to simultaneously manage both a heater and a refrigeration/cooling unit — maintaining temperature from both directions without additional switching equipment

Adjustable Differential (Hysteresis): User-configurable hysteresis from 0.3°C to 10°C prevents relay short-cycling and reduces wear on connected heating and cooling equipment

Compressor Protection Delay: Built-in 0–10 minute adjustable delay protects compressor-based cooling equipment from short-cycling damage during temperature fluctuations

Dual LED Display: Upper display shows the current measured temperature in real time; lower display shows the active setpoint — providing instant status monitoring at a glance

High-Temperature Alarm: Configurable upper temperature alarm triggers an alert when the measured temperature exceeds a user-defined safety threshold

Sensor Error Detection: Automatically displays an error code and deactivates relay outputs if the NTC sensor malfunctions, disconnects, or goes out of range — preventing uncontrolled temperature excursions

Simple Parameter Programming: All settings adjusted via three front-panel buttons — no special tools, software, or wiring expertise required for day-to-day operation

Panel Mount Design: Standard DIN-compatible panel cutout installation allows flush mounting into control panels, enclosures, refrigerator doors, and custom project boxes

Wide Measurement Range: Covers -50°C to +99°C in a single unit — suitable for freezer monitoring, fermentation temperature control, incubation heating, and warm room management
