Elitech STC-1000Pro is a plug-and-play digital thermostat for two-stage temperature control. It provides one temperature‑probe input and two pre‑wired output sockets — one for heating and one for cooling—so it can switch devices automatically based on setpoint and differential. The controller measures from −45 to 115°C and controls across −40 to 110°C with 0.1°C resolution and ±1°C accuracy. A 2.5‑inch LCD shows current and target values, and functions include high/low temperature alarms, sensor‑fault alarm, calibration, °C/°F selection, and compressor‑delay protection. Each output is rated 10 A at 100–250 VAC; the NTC 10K sensor cable is 2 m and the power cord 1.5 m. Available in UK/EU/US plug versions, typical uses include greenhouse planting, seedling heat mats, fridges/freezers, homebrew fermentation, and aquariums.
