INKBIRD’s ITC-310T-B is a dual‑relay, plug‑in temperature controller designed to automate heating and cooling equipment. It features 12 programmable time periods, each with its own temperature setpoint, allowing staged schedules for day/night or multi‑step processes. Users can choose single or cycle control modes, set durations from 1–999 minutes or hours, or 1–90 days, and switch between Celsius and Fahrenheit. The controller includes alarms for over‑temperature and sensor faults and uses a wired temperature probe for monitoring. With on/off outlets for simultaneous heating and cooling control, it suits indoor gardens, greenhouses, seed sprouting, and fermentation where precise environmental temperature is required. The operating range is specified at −50 to 120°C (−58 to 248°F), accommodating a wide variety of grow‑room scenarios.
