T-2 Pro CO2 Controller 14 A

The TechGrow T-2 Pro CO2 Controller (14A) is a combined CO2 and climate controller for grow rooms. It measures and displays CO2, temperature, and relative humidity, and regulates a CO2 device plus an exhaust fan. The 14 A fan output handles larger ventilation loads, while an 8 A CO2 relay controls dosing. CO2 setpoints span 300–2,000 ppm, expandable to 300–10,000 ppm with the compatible S-4 sensor (not included). Day/night switching is automatic via a light sensor in the CO2 probe. Power input is 100–240 V, 50/60 Hz. Features include adjustable hysteresis for CO2, temperature and humidity, a dosing counter, alarm thresholds, and non‑volatile memory. Dimensions are 21 × 24 × 10 cm; sensor is required and sold separately.
