Cli-Mate Smart Controller is a temperature-driven fan controller for regulating grow-room ventilation. Using a temperature sensor, it automatically adjusts fan speed to maintain a set point; two front dials let you set the desired temperature and the fan’s minimum speed. The unit is designed for straightforward use and basic climate stability in small indoor spaces. It operates on 220–240 V, 50 Hz single-phase power, is splash-resistant to IP44, and works across a 0–40 °C range. The Smart Controller is available in a 6.5-amp version and includes a temperature sensor for indoor use. Compact modules measure 120 × 60 × 50 mm (dimmer) and 100 × 50 × 50 mm (thermostat). This model is intended for controlling ventilation fans only.
