T-2 Pro CO2 Controller 4.5 A

TechGrow’s T‑2 Pro CO2 Controller (4.5A) combines CO2 dosing with basic climate control in one unit. It monitors CO2, temperature and relative humidity via an external TechGrow S‑4 sensor (not included) and drives a CO2 output and a fan output for extraction. Standard CO2 setpoint range is 300–2,000 ppm, expandable to 10,000 ppm with the S‑4 (0–10,000) sensor. Day/night operation is automatic through a light sensor integrated in the CO2 probe. Adjustable hysteresis for CO2, temperature and RH allows fine tuning. The controller accepts 100–240 V AC input; the CO2 relay is rated 8 A and the ventilation channel is fused at 5 A. Package includes mounting kit, 5 m UTP cable, spare fuse and manual. Enclosure measures 21 × 22 × 10 cm.
