Humi Dual Pro

TechGrow Humi Dual Pro is an environmental humidity controller that operates a humidifier and a dehumidifier independently to maintain a chosen level. It uses an external Temp/RH sensor (sold separately) to measure humidity and air temperature, with an adjustable setpoint from 10–90% RH. An external light sensor enables automatic day/night settings. The LCD and indicator LEDs aid setup and status checks. It operates on 100–240 V AC input and switches connected devices via onboard relays. The controller retains setpoint and hysteresis after power loss and supports UTP cabling and integration with other TechGrow devices, including the optional DL‑1 datalogger. Compatible sensors include the TechGrow S‑4 series; S‑2 sensors are not supported. Box contents include a mounting kit, 5 m UTP cable, spare fuse, and manual.
