Temp Contr STC-100A Single 220V

Description

The Haswill Electronics STC-100A Temperature Controller is an easy-to-use, economical, and highly reliable microcomputer thermostat designed for single-stage temperature regulation. Operating on a standard 220V AC current, this compact controller features a clear LED digital display and a single output relay that can be manually toggled to manage either a heating system or a cooling/refrigeration system. Equipped with a dedicated NTC thermistor sensor probe, it continuously monitors your target environment. With customizable parameters for temperature set-points, hysteresis (difference value) spacing, and compressor delay protection, it delivers steady climate management while protecting your hardware from rapid on/off cycling. Technical Specifications & Features Power Supply: 220VAC ±10%, 50/60Hz Temperature Measuring Range: −40 ∘ C to 99 ∘ C Temperature Control Range: −40 ∘ C to 70 ∘ C Sensor Array: 1 NTC Sensor Probe (2-meter cable included) Output Relay Capacity: 10A / 220VAC (Single output switch for either Heating or Cooling) Built-in Protection: Adjustable compressor delay timer to prevent rapid, short-cycling equipment damage. Compatible Appliances & Equipment Because the STC-100A features a universal, single-relay setup, it serves as an excellent replacement thermostat or DIY control upgrade for a wide variety of household, agricultural, and light commercial systems: Cooling & Refrigeration Applications: Beverage Coolers & Showcases: Great for commercial glass-door drink fridges and cake cabinets. Domestic/Commercial Refrigerators: Acts as a reliable replacement for broken internal fridge or freezer thermostats. Aquarium & Seafood Tanks: Maintains strict, safe water temperatures for sensitive aquatic life or live seafood holdings. Heating & Incubation Applications: Egg Incubators & Brooders: Highly popular for DIY poultry egg incubators requiring consistent, tight heating parameters. Greenhouses & Seedling Mats: Regulates localized soil heating pads or small greenhouse ventilation fans. Homebrewing & Fermentation: Controls heat wraps or fermentation chambers to keep beer, wine, or kombucha at optimal brewing temperatures. Terrariums & Reptile Habitats: Keeps pet enclosures uniformly warm. ⚠️ Installation Safety Notice: This unit utilizes a single relay, meaning it can only control one function at a time (it cannot run a heater and a cooler simultaneously like the STC-1000). Ensure the power source is completely disconnected before wiring. Keep the NTC sensor probe wire physically separated from the high-voltage mains lines to avoid electrical noise interference and erratic display readings.
