The Elitech STC-1000HX is a panel‑mount digital thermostat designed for two‑stage temperature control. It accepts a single temperature probe input and provides separate relay outputs for refrigeration and heating, enabling automatic switchover. The controller covers a wide control range of −50°C to 120°C and supports °C/°F display selection. Built‑in functions include temperature correction, compressor protection delay, sensor‑fault alarm, and over‑temperature alarm. The front panel features an IP67 waterproof rating and a clear LED display with straightforward keys. Typical uses include greenhouses and grow rooms; many users also drive fans from the cooling output when no compressor is used. This model is an update to the classic STC‑1000 form factor from Elitech.
