INKBIRD’s ITC-1000 is a panel‑mount, dual‑stage temperature controller for DIY environmental control. It uses an NTC sensor probe (2 m) to monitor temperature and switches separate heating and cooling outputs via 10 A relays. Users can set a target temperature and differential, calibrate readings, and enable compressor delay to protect refrigeration equipment. The controller covers −50 to 99°C (−58 to 210°F) with 0.1° resolution and ±1°C accuracy within the stated range. Alarms notify when temperature exceeds range or when a sensor error occurs. ITC‑1000 is available in 12 V DC, 110 V AC, and 220 V AC models, and is commonly used for home brewing, fermentation chambers, aquariums, reptile enclosures, incubators, and indoor planting. Typical controlled loads include air conditioners, freezers, and refrigerators.
