Cli-Mate’s Climate Controller (KC2011-T series) is a plug-and-play, stepless analog fan and temperature controller for maintaining indoor grow room conditions. It lets growers set minimum and maximum fan speeds and a hysteresis band so ventilation ramps proportionally around the target temperature, helping avoid rapid cycling. The unit integrates an indoor air-temperature sensor and provides two side inlets for connecting fans. Key specs include a 5–55 °C temperature range, 220/230 V 50 Hz supply, 1 °C per step switching differential, IP44 protection, and a 150 × 230 × 85 mm enclosure. Available in 7 A, 12 A, and 16 A models, it mounts with the included back plate and is calibrated using front-panel knobs for fully automatic environmental control.
