STC-1000 220V AC Digital Temperature Controller – All-Purpose Dual-Relay Thermostat with Sensor

Product Description

Take full control of your thermal environment with the STC-1000 All-Purpose Digital Temperature Controller. This versatile industrial-grade thermostat is designed to manage both heating and cooling systems simultaneously. At Robogears, we recommend the STC-1000 for high-precision applications like egg incubators, homebrewing fermentation, and aquarium climate control. Unlike simple thermostats, the STC-1000 features a dual-relay output, allowing it to switch on a heater when the temperature drops and an exhaust fan or compressor when it rises too high. Its bright LED display and tactile buttons make it easy to program setpoints, hysteresis (return difference), and compressor delay protection, ensuring your equipment stays safe and efficient.

Detailed Key Features

• Dual-Stage Control: Automatically switches between Heating and Cooling modes based on your temperature setpoint and "Return Difference" (Hysteresis) values.

• Compressor Delay Protection: Includes a programmable delay (1-10 minutes) to prevent frequent on/off cycling of refrigerators or AC units, extending their lifespan.

• Large LED Display: Provides real-time temperature monitoring in high-contrast red digits, visible even in low-light environments.

• Alarm Functions: Built-in audible and visual alarms trigger if the temperature exceeds your limits or if the sensor fails/shorts.

• Calibration Support: Allows you to calibrate the temperature reading to match a reference thermometer, ensuring professional-grade accuracy in your Pimpri facility.

Prototyping & Engineering Tips (Robogears Exclusive)

• The "Dry Contact" Rule: At our Pimpri workshop, we always remind makers that the relay outputs (5-8) are dry contacts (switches). They do not output 220V. You must loop your "Live" wire through the relay to power your heater or fan.

• Hysteresis (F2) Logic: To prevent your relay from "chattering" (flipping on/off too fast), set a sensible Return Difference (F2). For an incubator, 0.5°C is common; for a room heater, 1.0°C or 2.0°C is better.

• Sensor Extension: If you need to extend the NTC sensor cable, use high-quality shielded wire to prevent electrical noise from causing "Err" readings.

• Safety First: Since this module operates on 220V AC, always ensure it is mounted inside an insulated enclosure and that all connections are tight to prevent sparking or short circuits.

Package Includes

• 1 x STC-1000 220V AC Digital Temperature Controller
